Explanation: A VFD’s Stall protection function is a feature that allows the VFD to detect when the motor is stalling and take appropriate action to prevent damage. The VFD can use this function to monitor the motor’s speed and torque and detect when it is no longer able to turn the load. When a stall is detected, the VFD can reduce the torque to the motor and/or stop the motor to prevent damage. This feature can be especially useful in applications where the load is subject to sudden changes or where the motor is operating at or near its maximum torque capacity.
