Motor and inverter can be protected by the current cut-off negative feedback when motor is overload or locked-rotor.

当电机负载过载或堵转时，采用电流截止负反馈环节可保护电机和驱动器；

youdao

During the process of running, if it appears locked-rotor, the starter will automatically run for the reduction of motor speed to reach the goal of increasing the torque and reducing current of motor.

电机运转过程中，如出现堵转现象，随着电机转速的降低，起动器会自动投入运行，达到增加电机转矩，减少起动电流的目的。
