| Jog control |
Jog frequency range: 0.00Hz - 50.00 Hz, jog accleration / deceleration time 0.0S - 6500.0S |
| PLC multi stage speed operation |
Can achieve at most 16 stage speed operation by built-on PLC or control terminals. |
| Built-in PID |
Can convenient achieve precedure control close loop control system |
| Automatic voltage adjusting |
When power grid voltage changes, can keep output voltage stable automatically. |
| Control of losing speed from overvoltage and overcurrent |
Limit automatically the current and voltage during operation, to prevent frquent tripping operation of overcurrent and over voltage. |
| Quick limit of current function |
Decrease overcurrent breakdown at biggest level, to protect inverter run normally |
| Torque limit and control |
"Navy" characteristic, limit torque automatically during operation, to prevent frquent tripping operation of overcurrent, close loop vector control can achieve torque control. |
