11.11
Load characteristics fault detection
This function is used to monitor whether the load is operating in normal condition by storing the speed/torque relationship in
the inverter to detect mechanical faults or for maintenance. When the load operating condition deviates from the normal range,
the protective function is activated or the warning is output to protect the inverter or the motor.
