Product Description
Discription of VDF730 Series Inverter
The VDF730 series AC drive is a general-purpose AC drive, which implements V/F control on AC asynchronous motors. It is used to drive various automation production equipment of different felds involving textile, paper-making, wiredrawing, machine tool, packing, food, fan and pump. Featuring large startup torque and 8-speed running, it also supports closed-loop process control and networking, and can be commissioned easily

| Basic functions | Highest freq | 500hz |
| Carrier freq | 1KHZ-16KHZ, it can be adjust carrier freq automatically according load characteristics | |
| Step of input freq | Digital setting:0.01HZ, analog setting : highest freq 0.025% | |
| Control mode | V/F control | |
| Startup torque | P type machine 130% | |
| Speed range | 1:50 | |
| Speed stabilization accuracy | ±1% | |
| Overloading ability | G type machine 150% rated current 60s, P type machine 130% rate current 60s | |
| Torque boost | Automatically arise torque; arise torque 0.1%-30.0% by hand | |
| V/F curve | Linear V/F , multiple dot V/F; | |
| Speed up/down curve | Linear or S curve speed up/down 2 kinds of speed up/down time, range 0.0-300min | |
| DC braking | DC braking freq:0.00hz-maxi freq, braking time:0.0s-36.0s, braking current:0.0%-100.0% | |
| Control of Jog-for-run | Jogging freg range:0.00HZ-50.00HZ; speed up/down time at jogging:0.0s-6500s | |
| Simple PLC,multi-stange running | It can perform running at 8-stage speed through built-in PLC or control terminals | |
| Bulit-in PID | Easy to form program control loop control system | |
| Auto voltage regulation(AVR) | When system voltage change, able to keep output voltage constant automatically | |
| Compensation of rotation error | Rational setting of compensation for rotation error, can compensate the change of rotation speed due to load, to achieve higher control accuracy of speed | |
| Auto limiting current | Limit the operation current, prevent frequently tripping due to over-current | |
| Control of over-voltage speed loss | Limit the operation voltage, prevent frequently tripping due to over-voltage | |
| Magnetic flux braking | To achieve shorter speed-down/braking time through this mode | |
| Over-modulation | Utilize over-modulation technology for over the basic freq, to get higher voltage output, increase hi-freq output torque of the motor. | |
| No stop at instantaneous | When voltage fall down at short time, it can keep inverter busbar voltage constant, to avoid tripping. | |
