Frequency setting modeOperator panel, analog AI1, AI2, AI3, terminal UP / DN control, communication control, PLS pulse frequency
DC braking capacityDC braking frequency: 0.0 ~ 300Hz DC braking current: 0.0% to 100%
Braking unit4T15G and below the standard built-in brake unit 4T18.5G ~ 75G optional built-in brake unit and above require external 4T93G
PLC multispeed16-speed operation can be achieved through the built-in control terminals or at most PLc
Common DC busMultiple drives shared DC bus, energy automatic equalizer
Automatic voltage regulator (AVR)When the grid voltage changes, can automatically maintain output voltage stability
Overload150% rated current 60S; 180% rated current 3S
Overvoltage stall controlAutomatically limits current and voltage during operation, avoid frequent over-current protection
Fast current limiting function

Minimize overcurrent fault, as far as possible to ensure that the module is not damaged, protect the normal operation of the drive.

Torque limit and control"Excavator" feature automatically limits the torque during operation, avoid frequent over-current trip, closed loop vector control mode can be achieved torque control.
