Function description
If the mechanical load is too high, the motor may block. For a blocked motor, the motor current
corresponds to the set current limit without the speed reaching the specified setpoint.
If the speed lies below the speed threshold p2175 for the time p2177 while the motor current
reaches the current limit, the converter signals "Motor blocked" and fault F07900.
