1 SERVO MOTOR MAINTENANCE 
Generally, βis series AC servo motors have no parts that wear off or that 
must be replaced periodically, unlike DC servo motors, which have 
brushes that must be replaced periodically. 
However, you should perform periodic maintenance for servo motors 
so as to keep their initial performance as long as possible and to prevent 
breakdowns. AC servo motors have precision sensors. Their incorrect

1.1 RECEIVING AND KEEPING AC SERVO MOTORS 
When you receive an AC servo motor, make sure that: 
• The motor is exactly the one you ordered, in terms of model, shaft, 
and sensor specifications. 
• No damage has been caused on the motor. 
Because FANUC inspects servo motors strictly before shipment, you 
do not, in principle, have to inspect them when you receive them.


key: chroma:document
string_value:
The servo motors should be kept indoors as a rule. The storage 
temperature range is -20 to +60°C. Do not place or install AC servo 
motors in the place where: 
• It is extremely humid and dew is prone to form, 
• There is a steep change in temperature, 
• There is constant vibration, which may cause damage to the shaft 
bearings, or 
• There is lots of dust and trash.

1.2 DAILY INSPECTION OF AC SERVO MOTORS 
Before starting operation, or periodically (once a week or month), you 
should inspect the AC servo motors in terms of the following: 
(1) Vibration and noise
 Check the motor for abnormal vibration (by the hand) and noise 
(by the ear) when the motor is: 
• Not rotating 
• Rotating at low speed 
• Accelerating or decelerating


key: chroma:document
string_value:
If you find anything unusual, contact your FANUC service staff. 
(2) Damage on the outside
 Check the Pulsecoder cover (red plastic) for crevices and the 
motor surface (black coating) for scratches and cracks. 
 If you find a crevice in the Pulsecoder cover, you should replace it. 
For how to replace, see the description about the Pulsecoder in 
Section 1.4. If you are not sure about replacement, contact you 
FANUC service staff.

FANUC service staff. 
 If there is a scratch or crack on the motor surface, the user should 
repair it by himself as required. If coating has come off, dry the 
portion of interest (or the entire surface) and coat it with paint for 
machines such as urethane paint.

1.3 PERIODIC INSPECTION OF AC SERVO MOTORS 
We recommend that you inspect the AC servo motors for the following 
items at least once a year. 
(1) Observation of torque command (TCMD) and speed command 
(VCMD) waveforms
 Observe normal voltage waveforms with an oscilloscope, and 
keep notes of them. During periodic inspection, check the current 
waveforms with the records.


key: chroma:document
string_value:
waveforms with the records. 
 The waveforms vary according to the operating conditions such as 
load and cutting speed. Note that you should make comparisons 
under the same condition (for example, during fast traverse to the 
reference position or low-speed cutting). 
For a description of the measurement method, see Appendix E, 
"SERVO CHECK BOARD". 
(2) Diagnosis by waveforms
 Check the measured waveforms to see whether: 
<1> The peak current is within the limit to the current in the

deceleration.(TCMD)
 The limit to the amplifier current is listed below. A voltage of

NOTE 
1 The increment system in the current CNCs 
corresponds to the user-specified unit in this servo 
amplifier module. For example, when an amount of 
movement is specified in any of the current CNCs, 
the weight for a specified value of 1 is determined by 
parameter switching. In increment system B, the 
weight for a specified value of 1 is 1 µ. This servo 
amplifier module does not perform parameter 
switching, but requires the user to determine the


key: chroma:document
string_value:
weight for a specified value of 1. 
2 Do not change the value of a parameter not 
included in the parameter list because that 
parameter may be used for an internal variable. 
For example, parameter No. 029 is used for an 
internal variable. Even if this parameter has a 
nonzero value, ignore the parameter without 
changing the value.

 CAUTION 
1 There is a limit to the number of writes to the

(tens of thousands of writes). For this reason, set 
NEPR to 1 if parameters are to be rewritten 
frequently using peripheral device control or a direct

Otherwise, an EEPROM parity mismatch occurs, 
with the result that a parity error occurs and

 If parameters are rewritten from the MDI using the

The formula for converting the amount of movement per rotation axis revolution into 
the movement amount of the absolute-position detector (Lp) is as follows:

string_value:
conversion, Lp contains a fractional part. Because the servo amplifier module rounds 
off Lp to the nearest integer value, fractional parts are accumulated if revolution in one 
direction continues, possibly causing a positional error the next time the power is 
turned on. 
(Condition 1) If K is less than 1, the "amount of movement per rotation axis revolution 
(parameter No. 141) × K" contains a fractional part. 
(Condition 2) Lp contains a fractional part.

If either of the conditions is satisfied and the use of the servo amplifier module involves 
continuous revolution in one direction, you can set bit 6 (MVZPFR) of parameter No.

105 and 106) is 50/1, the lower limit is 62, causing an overflow to 
occur. Multiply CMR and the denominator for the number of 
pulses per motor revolution (No. 105) by two to change parameter 
32 to 4 and parameter 105 to 100. (The user unit becomes 1/2.)

This parameter is related to a position loop time constant. The larger the 
value set for this parameter, the more quickly the NC responds to 
commands, and the less time is required for positioning. If the 
parameter is set to an excessively large value, however, hunting (at 5 to 
15 Hz) may occur during movement, or overshoot may occur at a stop.

116 Velocity loop gain override during velocity control (%) 
 [Size] 2-byte 
 [Standard value] 0 (overriding not performed) 
Set this parameter if the system is switched between position control 
and velocity control. 
When the system enters velocity control mode, the velocity loop 
proportional gain and the integral gain that are used in position control 
are multiplied by the above override.


key: chroma:document
string_value:
The relationships among the velocity loop proportional gain, integral 
gain, load inertia ratio, and the velocity loop gain override during 
velocity control are explained using the following example: 
Assume the following: 
Integral gain = 100 
Proportional gain = -500 
Load inertia ratio = 128 
Velocity loop gain override during velocity control = 200% 
[Gain during position control] 
 Integral gain = 100 × (1+128/256) = 150 
 Proportional gain = -500 × (1+128/256) = -750


key: chroma:document
string_value:
[Gain during velocity control] 
 Integral gain = 100 × (1+128/256) 200/100 = 300 
 Proportional gain = -500 × (1+128/256) 200/100 = -1500 
Thus, the gain with the load inertia ratio taken into consideration is 
multiplied by the gain override during velocity control.

D.1 POWER MATE CNC MANAGER FUNCTIONS (Series 16, 18, 
21, Power Mate) 
D.1.1 Overview 
This chapter explains the power mate CNC manager functions used by 
the CNC to set up and display the types of data for servo amplifier 
module. 
The functions provided are: 
(1) Current position display (absolute/machine coordinate) 
(2) Parameter display and setting 
(3) Diagnosis 
(4) System configuration, amplifier ID 
(5) Alarm 
NOTE


key: chroma:document
string_value:
(5) Alarm 
NOTE 
1 These functions may not be available depending on 
the CNC model or option with which they are used. 
2 These functions cannot be used on the DPL/MDI. 
D.1.2 I/O Link Connection 
The CNC assigns I/O addresses for it. Because the CNC exchanges data 
with an servo amplifier module in 16-byte units, it is necessary to set the 
number of input/output points to 128. Up to eight servo amplifier 
module can be connected.


key: chroma:document
string_value:
module can be connected. 
The names of modules used for I/O link connection are OC02I (16-byte 
input) and OC02O (16-byte output). The BASE and SLOT are always 0 
and 1, respectively. 
D.1.3 Function Selection and Termination 
D.1.3.1 Selection 
Each power motion manager function can be selected by first pressing 
the next-menu key (rightmost soft key) on the CNC system screen 
several times until [PMM] is displayed, then pressing this soft key. The


key: chroma:document
string_value:
initial screen, that is, the system configuration screen, for the power 
motion manager appears. On this screen, the desired function can be 
selected by pressing the corresponding soft key. 
After a power motion manager function has been selected, if a function 
key on the MDI is pressed to select another function, then the 
<SYSTEM> function key is pressed, the previous screen of the function 
appears again. In this case, however, data being input has been 
canceled.

D.1.3.4 Disabling the Power Mate CNC Manager Functions 
Once the data necessary for a connected servo amplifier module has 
been set up or confirmed, it is possible to discontinue communication 
with the power mate CNC manager (PMM) to give priority to those 
commands sent from the ladder program of the CNC to slaves. This is 
done by setting bit 3 of parameter P960 to 1. 
Communication between the CNC and a servo amplifier module via an 
FANUC I/O Link is surrendered to the ladder program.


key: chroma:document
string_value:
When this parameter is 1, only communication-independent items, such 
as a title and function name, are displayed on the screen. The following 
message appears to indicate that communication has been discontinued.

D.2.5 Note 
I/O Link connection 
To use I/O Link β as a slave of I/O Link, assign I/O addresses on the 
CNC side. Since I/O data for slaves is handled in 16-byte units, be sure 
to specify 128 input/output points. 
A maximum of eight slaves can be connected. 
The module names are OC021 (16-byte input) and OC020 (16-byte 
output). 
BASE is always 0 and SLOT is always 1. 
Power Mate CNC manager neglect function


key: chroma:document
string_value:
After necessary data settings and confirmation are made for each of 
connected slaves, it is possible to stop communication by the Power 
Mate CNC manager function to precede commands from the ladder on 
the CNC side to each slave. 
When bit 3 (PMN) of parameter No. 960 is set to 1, all communication 
with slaves over I/O Link is open to the ladder. Setting this parameter 
to 1 also disables the Power Mate CNC manager function.

(6) Torque command (TCMD) 
 The TCMD signal is used to output a motor torque command. 
When the motor is rotating at high speed, the current indicated by 
this signal may differ from the actual motor current (IR or IS) 
because of the back electromotive force in the motor.

NOTICE OF FEEDRATE PARAMETERS 
Add the following NOTE to the parameters No.040, No.043, No.054, No.061, No.066, 
and No.067 of "B.3 FEEDRATE PARAMETERS" and the parameter No.059 and 
No.060 of "B.4 ACCELERATION/DECELERATION CONTROL PARAMETERS". 
NOTE 
1 The maximum of the setting range is shown in the following table according


key: chroma:document
string_value:
to the setting value of N. When the setting value exceeds this maximum, 
the actual feedrate is not correct. 
Setting value of N Maximum of setting range 
0-3 65535
4 49151
5 4915
6 491
7 49
8 4
2 When N is equal to or less than 3, the actual feedrate has the error of 7 or 8 
in N=3 (75 in N=2, 750 in N=1, 7500 in N=0), and the feedrate may be lower 
than the setting value. This is caused by the computation precision. The


key: chroma:document
string_value:
smaller the feedrate is given, the bigger the relative error becomes. In this 
case, adjust the setting value. For example, when “40” is set in N=3, the 
actual feedrate is 37. The actual feedrate is all 37 in the range of setting 
value 37 to 44. When “45” is set, the actual feedrate is 45.

Notice Concerning Reference Position Setting
(1) Abstract 
In case reference position is set by parameter (No.1815#4 is set) with absolute 
detector, when reference position is lost by some reason, it becomes impossible


key: chroma:document
string_value:
to set accurate reference position again by FANUC service engineer or 
end-user. In such a case, it is necessary for Machine tool builder to set 
reference position. 
In this manual, notice concerning reference position setting is summarized in 
order to set reference point in the field as early as possible. 
(2) Reference position setting methods and each merit and demerit 
There exist following methods for reference position setting, and we are going 
to show merits and demerits of each method.


key: chroma:document
string_value:
Note) Reference Position Setting with Mechanical Stopper is not supported in I/O Link βi.
Depending on above situation, we are going to show points to be concerned 
concerning reference position setting. 
Method for 
Reference Position 
Setting 
Method Merit Demerit 
Manual Reference 
Position Return 
Reference position return is 
executed by both grid 
generated from position 
detector and deceleration dog 
• Most reliable method to 
reproduce reference 
position 
• Deceleration dog is


key: chroma:document
string_value:
• Deceleration dog is 
required. 
Reference Position 
Setting without Dog 
Grid generated from position 
detector is used. 
Reference position setting is 
executed just before of 
reference position and setting 
is executed without dog. 
• Deceleration dog is 
unnecessary. 
• So long as start point 
of reference position 
is clear, reference 
position can be set 
easily. 
• In case start point of 
reference position is 
unclear, reference 
position can not be set.
Reference Position

Reference Position 
Setting with 
Mechanical Stopper 
Note) 
First axis pushes mechanical 
stopper, and withdraws 
pre-decided distance from the 
mecahnical stopper, then 
reference position is set. 
• Deceleration dog is 
unnecessary. 
• Reference position 
can be set easily. 
• Considering the 
distortion of mechanical 
stopper or some 
materials between axis 
and stopper, reference 
position setting is not 
accurate. 
Reference Position 
External Setting


key: chroma:document
string_value:
External Setting 
Reference position setting by 
setting external signal to 1 
Available only in case that 
accurate reference position is 
NOT required. 
• Deceleration dog is 
unnecessary. 
• Reference position 
can be set easily. 
• Reference position 
setting is not 
accurately.

(3)Points to be concerned concerning Reference Position Return 
Data of pulse corder for absolute position detection is back-upped by battery. 
Reliability of this back-up data is maintained as much as possible.


key: chroma:document
string_value:
On the other hand, because of following reasons, there is a possibility to lose 
reference position. 
- Voltage of battery becomes lower than Battery Zero Level. 
- Failure of pulse coder or motor, then replacement becomes necessary 
- Change of parameters, which makes reference position lost, such as grid 
shift 
etc. 
In case reference position is lost, it is necessary to establish reference position 
again. However, with machines in operation in the field, it becomes sometimes


key: chroma:document
string_value:
difficult to establish reference position with any reason shown below. 
- Reference position setting has been set by parameter (No.1815#4) and it is 
difficult to move to the accurate reference position. 
- In case Reference Position Setting without Dog is applied, “Eye Mark” to 
start reference position return has been lost or disappeared or can not be 
seen by mechanical cover and so on. Therefore, it is difficult to specify the 
start position to reference position return.


key: chroma:document
string_value:
- In case Reference Position Setting with Mechanical Stopper is applied, 
there are some distortions of mechanical stopper or some materials 
between axis and stopper. Therefore, the mechanical stopper position 
shifts.
- - In case Reference Position External Setting is applied, “Eye Mark” to 
show reference position has been disappeared or missing.
etc. 
In these cases, it often takes log time to establish reference position again, as a 
result, causes large trouble to end-user site.


key: chroma:document
string_value:
So in order to make reference position establish much easier, we would like to 
ask machine tool builders following notice.

avoid distortion of mechanical stopper or some materials between axis and stopper. 
 
z Reference Position External Setting should be applied only in case that it is NOT necessary to
establish reference position at accurate position, and “Eye Mark” should be prepared to set of 
reference position. 
z Please attach manual to the machine tool describing “How to establish reference position of 
each axis”.

 CAUTION 
 - Do not use the brake built into a motor for braking. 
The brake built into a servo motor is designed for holding. If the brake is used for braking, a failure can 
occur. 
 - Ensure that motors are cooled if they are those that require forcible cooling. 
If a motor that requires forcible cooling is not cooled normally, it may cause a failure or trouble. For a


key: chroma:document
string_value:
fan-cooled motor, ensure that it is not clogged or blocked with dust and dirt. For a liquid-cooled motor, 
ensure that the amount of the liquid is appropriate and that the liquid piping is not clogged. For both types, 
perform regular cleaning and inspection. 
 - When storing a motor, put it in a dry (non-condensing) place at room 
temperature (0 to 40 °C). 
If a motor is stored in a humid or hot place, its components may get damaged or deteriorated. In addition,


key: chroma:document
string_value:
keep a motor in such a position that its shaft is held horizontal and its terminal box is at the top. 
 - FANUC motors are designed for use with machines. Do not use them for any 
other purpose. 
If a FANUC motor is used for an unintended purpose, it may cause an unexpected symptom or trouble. If 
you want to use a motor for an unintended purpose, previously consult with FANUC. 
Note 
NOTE 
 - Ensure that a base or frame on which a motor is mounted is strong enough.


key: chroma:document
string_value:
Motors are heavy. If a base or frame on which a motor is mounted is not strong enough, it is impossible to 
achieve the required precision. 
 - Do not remove a nameplate from a motor. 
If a nameplate comes off, be careful not to lose it. If the nameplate is lost, the motor becomes unidentifiable, 
resulting in maintenance becoming impossible. 
 - When testing the winding or insulation resistance of a motor, satisfy the 
conditions stipulated in IEC60034.


key: chroma:document
string_value:
Testing a motor under a condition severer than those specified in IEC60034 may damage the motor.

B-65425EN/02 SAFETY PRECAUTIONS
s-13 
 WARNING 
- Notes on replacing the battery of the absolute Pulsecoder
 Replace the battery only while the power is on. If the battery is replaced while the power is turned off, 
the stored absolute positioning data will be lost. If the battery is installed in the βi-B series servo 
amplifier, open the door of the power magnetics cabinet and enter the emergency stop state without


key: chroma:document
string_value:
turning off the control power. Interrupt the input of the power system of the amplifier and then replace 
the battery. Replacement work should be done only by a person who is trained in the related 
maintenance and safety requirements. The power magnetics cabinet in which the servo amplifier is 
mounted has a high-voltage section. This section presents a severe risk of electric shock. 
- Check the number of any alarm.


key: chroma:document
string_value:
If the machine stops upon an alarm being issued, check the alarm number. Some alarms indicate that a 
component must be replaced. If the power is reconnected without first replacing the failed component, 
another component may be damaged, making it difficult to locate the original cause of the alarm. 
- Before resetting an alarm, ensure that the original cause of the alarm has been removed. 
- Contact FANUC whenever a question relating to maintenance arises. 
- Notes on removing the amplifier


key: chroma:document
string_value:
Before removing the amplifier, first ensure that the power is shut off. Be careful not to jam your fingers 
between the power magnetics cabinet and amplifier. 
Caution 
 CAUTION 
- Ensure that all required components are mounted. 
 When replacing a component or PC board, check that all components, including the snubber capacitor, 
are correctly mounted. If the snubber capacitor is not mounted, for example, the IPM will be damaged. 
- Tighten all screws firmly.


key: chroma:document
string_value:
- Tighten all screws firmly. 
- Check the specification code of the fuse, PC board, and other components.
 When replacing a fuse or PC board, first check the specification code of the fuse or PC board, then 
mount it in the correct position. The machine will not operate normally if a fuse or PC board having 
other than the correct specification code is mounted, or if a fuse or PC board is mounted in the wrong 
position. 
- Mount the correct cover.


key: chroma:document
string_value:
- Mount the correct cover.
 The cover on the front of the amplifier carries a label indicating a specification code. When mounting 
a previously removed front cover, take care to mount it on the unit from which it was removed. 
- Notes on cleaning the heat sink and fan 
1) A dirty heat sink or fan results in reduced semiconductor cooling efficiency, which degrades 
reliability. Periodic cleaning is necessary.


key: chroma:document
string_value:
2) Using compressed air for cleaning scatters the dust. A deposit of conductive dust on the amplifier 
or peripheral equipment will result in a failure. 
3) To clean the heat sink, do so only after turning the power off and ensuring that the heat sink has 
cooled to room temperature. The heat sink becomes extremely hot, such that touching it during 
operation or immediately after power-off is likely to cause a burn. Be extremely careful when 
touching the heat sink.

 CAUTION 
- Note on inserting or removing a connector 
 Unless otherwise specified, do not insert or remove any connector while the power is turned on. 
Otherwise, the amplifier may fail. 
Note 
NOTE 
- Ensure that the battery connector is correctly inserted.
 If the power is shut off while the battery connector is not connected correctly, the absolute position 
data for the machine will be lost. 
- Store the manuals in a safe place.


key: chroma:document
string_value:
The manuals should be stored in a location where they can be accessed immediately it so required 
during maintenance work. 
- Notes on contacting FANUC
 Inform FANUC of the details of an alarm and the specification code of the amplifier so that any 
components required for maintenance can be quickly secured, and any other necessary action can be 
taken without delay.

4.2 REPLACING BATTERY FOR ABSOLUTE PULSECODERS 
4.2.1 Overview 
• When the voltage of the batteries for absolute Pulsecoders becomes low, alarm 307 or 306 occurs, with 
the following indication in the CNC state display at the bottom of the CNC screen. 
Alarm 307 (alarm indicating the voltage of the battery becomes low) : 
 The indication "APC" blinks in reversed display. 
Alarm 306 (battery zero alarm) :


key: chroma:document
string_value:
The indication "ALM" blinks in reversed display. 
• When alarm 307 (alarm indicating the voltage of the battery becomes low) occurs, replace the battery 
as soon as possible. In general, the battery should be replaced within one or two weeks, however, this 
depends on the number of Pulsecoders used. 
• When alarm 306 (battery zero alarm) occurs, Pulsecoders are reset to the initial state, in which absolute


key: chroma:document
string_value:
positions are not held. Alarm 300 (reference position return request alarm) also occurs, indicating that 
reference position return is required. 
• In general, replace the batteries periodically within the service life listed below.
- A06B-6050-K061 or D-size alkaline dry cells (LR20) : Two years (for each six-axis 
configuration) 
- A06B-6093-K001 : Two years (for each one-axis configuration)

1 The absolute Pulsecoder of each of the αi series servo motors or βi series servo 
motors (βiS0.4 to βiS40, βiSc, and βiF) has a built-in backup capacitor. Therefore, 
even when the power to the servo amplifier is off and the batteries are replaced, 
reference position return is not required if the replacement completes within less 
than 10 minutes. Turn the power on and replace the batteries if the replacement 
will take 10 minutes or more.

• If a low battery voltage or a battery voltage of 0 V is indicated by an APC (absolute Pulsecoder) alarm, 
replace the battery. If a battery voltage of 0 V is indicated, you need to make a zero point return. 
• The absolute Pulsecoder of the αi series servo motor and the βi series servo motor (βiS 0.4 to 
βiS 40, βiSc, βiF) is incorporated with a backup capacitor as standard. This backup capacitor enables

an absolute position detection to be continued for about 10 minutes. Therefore, no zero point return 
need be performed if the time during which servo amplifier power is kept off for battery replacement is 
within 10 minutes. 
 The Pulsecoder of some of the βiS series servo motors (βiS 0.2 to βiS0.3) does not include a backup

4.3 HOW TO REPLACE THE FUSES AND PRINTED CIRCUIT 
BOARDS 
4.3.1 How to Replace the Fuses and Printed Circuit Boards 
In the βiSV-B series, a printed-circuit board can be removed and inserted from the front of the servo 
amplifier. 
NOTE 
1 If a fuse blows, it is likely that there is a short-circuit in the power supply for a 
device (such as a sensor) connected to the Servo Amplifier.


key: chroma:document
string_value:
After checking that all devices connected to the Servo Amplifier are normal, 
replace the fuse. 
 If you do not remove the cause, it is very much likely that the fuse will blow again. 
2 Do not use any fuse not supplied from FANUC. 
3 Before replacing a fuse, check a marking on it with that on the printed-circuit 
board. Be careful not to mount a fuse with an incorrect rating.

3.3.1 βiSVSP-B Power Supply Section


key: chroma:document
string_value:
The Power Supply section of the βiSVSP-B series is controlled by software. This allows power supply 
information to be monitored on the CNC. Using this information, it is possible to diagnose failures resulting 
from power supply fluctuations. 
3.3.1.1 Amplifier group number 
When a Servo/Spindle Amplifier is connected to the βiSVSP-B series as an additional axis, all of them are 
defined collectively as a single "amplifier group". This means that a system having multiple βiSVSP-B

string_value:
series or having two or more βiSVSP-B series and αiPS-B series has more than one amplifier group. A 
unique number is assigned to each of these amplifier groups, and such numbers are called "amplifier group 
numbers". 
 
3.3.1.2 PS control axis 
In an amplifier group, "slave numbers", such as 10, 20, 30..., and 150, are assigned to the Servo/Spindle 
Amplifiers connected to the βiSVSP-B in order of connection*NOTE. In each amplifier group, the axis with

 This means the connection of inter-amplifier communication linked by connector 
CXA2x. 
It does not mean the connection of FSSB. 
 With the βiSVSP-B series, the spindle axis of the amplifier is always the PS control 
axis. 
3.3.1.3 Parameter setting for specifying the PS control axis 
Using the βiSVSP-B series requires the following procedure.
Parameter setting procedure


key: chroma:document
string_value:
Parameter setting procedure 
For the βiSVSP-B series, set the PS control axis as follows, so that the CNC software recognizes the PS 
control axis. 
PS control axis setting: For the spindle axis, an amplifier group number needs to be set in parameter No. 
4657. 
This setting can be made automatically with the following procedure. 
<1> Set No. 11549#0(APS) = 1. 
<2> On CNC ALARM MESSAGE screen, "PW0000 POWER MUST BE OFF" will be displayed.


key: chroma:document
string_value:
<3> Turn the power to the CNC off, then on again. When the CNC is restarted, a value is automatically set 
in parameter No. 4657, completing the PS control axis parameter setting. 
* Upon completion of the automatic parameter setting, No. 11549#0 returns to 0. 
* If the amplifier configuration is changed, the alarm "PS CONTROL AXIS ERROR" occurs, in which 
case perform the automatic setting again.

3.3.2.2 Start-up of an individual servo axis 
The conventional servo amplifiers of the βiSVSP series do not become ready unless all axes satisfy the 
start-up conditions. With the servo amplifier of the βiSVSP-B series, by contrast, any axis that satisfies the 
start-up conditions can become ready independently.

content of the alarm. A change has been made in the servo amplifier of the βiSVSP-B series so that, if an

not-ready status while the servo amplifier keeps the other servo axes ready. 
No restrictions imposed in the event of an alarm

conventional servo amplifiers of the βiSVSP series, can be set individually for each servo axis.

string_value:
Setting dummy axes 
Starting up a specific servo axis in a conventional servo amplifier of the βiSVSP series requires attaching a 
dummy connector to each servo axis that is not in use. With the servo amplifier of the βiSVSP-B series, it is 
possible to start up any arbitrary servo axis alone, thus eliminating the need to attach dummy connectors to 
unused axes.

Sharing the amplifier among multiple paths 
If a conventional amplifier of the βiSVSP series is shared among multiple paths when the amplifier enters 
the not-ready status for an axis used by one path, it is necessary to input the signal for ignoring the V 
ready-off alarm to prevent the amplifier from becoming not ready for the axes used by the other paths. This 
is not necessary for the servo amplifier of the βiSVSP-B series.


key: chroma:document
string_value:
CAUTION 
1 Notes on synchronization control 
 If an alarm occurs on one of the axes used under synchronization control, it is 
necessary for the amplifier to become not ready immediately for the other axes as 
well in order to prevent machine distortion. To meet this requirement, be sure to 
enable the servo software’s "servo alarm two-axis simultaneous monitor function" 
for the axes under synchronization control. 
 In some cases where synchronization control or tandem control is implemented


key: chroma:document
string_value:
using two axes of a conventional amplifier of the βiSVSP series, the amplifier 
becomes not ready for both axes simultaneously in the event of an alarm and this 
plays a similar role to that of the "servo alarm two-axis simultaneous monitor 
function". 
 Because the ready status conditions for the servo amplifier of the βiSVSP-B series 
for each axis are independent of one another, there is no substitute for the "servo 
alarm two-axis simultaneous monitor function". Therefore, be sure to enable the


key: chroma:document
string_value:
"servo alarm two-axis simultaneous monitor function" for axes under 
synchronization control. Refer to the Parameter Manual for detailed descriptions 
of the "servo alarm two-axis simultaneous monitor function" and the related 
parameter settings. 
2 If an alarm common to all axes occurs (such as a DC link low-voltage alarm), all 
the axes driven by the multi-axis amplifier are affected by the alarm in the same 
manner as in the conventional amplifier, resulting in the amplifier becoming not


key: chroma:document
string_value:
ready simultaneously for all the axes and a dynamic brake being applied to bring 
all of them to a halt. 
3 If an emergency stop signal (input signal to the connector CX4 of the PS) is input, 
the amplifier becomes not ready for all axes and applies a dynamic brake to bring 
all of them to a halt.
