control.
Automatic voltage
regulation(AVR)
Automatically maintain a constant output voltage when
the voltage of electricity grid changes
"Excavator" feature - torque is automatically limited
during the operation to prevent frequent over current trip;
the closed-loop vector mode is used to control torque.
