| Simple PLC |
Up to 16 speeds via the simple PLC function or DI terminals |
| Onboard PID |
Process-controlled closed loop control system |
Auto voltage
regulation (VR) |
Keep constant output voltage automatically when grid voltage fluctuates. |
Overvoltage/
Overcurrent stall
control |
The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage/overcurrent. |
| Fast current limit function |
Protect inverter from overcurrent malfunctions. |
Torque limit and
control |
It can limit the torque automatically and prevent frequent over current tripping during the running process. Torque control can be implemented in the FVC mode. |
Power dip ride
through |
The regenerative energy from load compensates the voltage reduction so that the inverter can continue to run for a short time. |
