Compensation
Manual setting: 0.0~30% of rated output
Automatic compensation: according to output current and
motor parameter
Automatic
Current-limiting and
Voltage-limiting
During acceleration, deceleration or steady running, detect
automatically the current and voltage of motor stator, and
control it within bounds based on unique algorithm, minimize
fault-trip chance
