Process-controlled closed loop control system |
Auto voltage
regulation (AVR) |
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. |
| Stop for a second |
When the instantaneous outage occurs, the voltage is compensated by the load feedback energy to keep the converter running for a short time. |
