PLC multiple speed

To achieve a 16-segment speed run using built-in PLC or terminal control.

Common Dc bus

Multiple drives utilize a single DC bus for energy equilibrium.

Auto voltage regulation (AVR)

Enable the system to maintain a constant output voltage despite grid fluctuations.

Over load tolerance capability

G type model: 150% rated current for 60 seconds, 180% rated current for 3 seconds.

P-type Model: Rated for 120% current for 60 seconds, 150% current for 3 seconds.

Stall protection control when over current, over voltage

Implement limiting automation to control the running current and voltage, thereby preventing frequent occurrences of overcurrent and overvoltage.

Rapid current limit function

Minimize the breakage of the IGBT module to protect the AC Drive and maximize the reduction of overcurrent faults.

Torque limit and torque control

The "Excavator" features automatic torque limiting during motor operation. Torque control is available in closed-loop vector control mode.
