V/F Controlled Self-developed Software VFD Inverter 7.5kw 220V Input 380v Output
►Products Features:
| Standard functions |
V/F curve | Straight-line V/F curve Multi-point V/F curve N-powerV/F curve (1.2-power, 1.4-power, 1.6-power, 1.8- power, square) |
| V/F separation | 2 types: complete separation; half separation | |
|
Acceleration/deceleration curve | Straight-line ramp S-curve ramp Four groups of acceleration/deceleration time with the range of 0.00s~65000s | |
|
DC braking | DC braking frequency: 0.00 Hz ~ maximum frequency Braking time: 0.0~100.0s Braking trigger current value: 0.0%~100.0% | |
| JOG control | JOG frequency range: 0.00Hz~50.00 Hz JOG acceleration/deceleration time: 0.00s~65000s | |
| Built-in PLC, multiple speeds | It realizes up to 16 speeds via the simple PLC function or combination of DI terminal states | |
| Built-in PID | It realizes closed loop control system easily. | |
| Auto voltage regulation (AVR) | It can keep constant output voltage automatically when the mains voltage fluctuation. | |
| Overvoltage/ Over current stall control | The current and voltage are limited automatically during the running process so as to avoid frequently tripping due to overvoltage/over current. | |
| Rapid current limit function | It can auto limit running current of frequency inverter to avoid frequently tripping. | |
| Torque limit and control | (Excavator characteristics) It can limit the torque automatically and prevent frequently over current tripping during the running process. Torque control can be implemented in the VC mode. |
