Technical Indications of ZVF9V-G/P Series Variable frequency drive:
1: Speed control mode: NO PG vector control(SVC). V/F control.
2: Output Frequency range: 0.00~400.00Hz
3: Instruction Passage Mode: Operator Panel, Terminal Control, Long-distance communication control.
4: PID Frequency setting the signal: Number keyboard, Analog setting ( current, voltage signal ). Long-distance setting, Multi-Phase speed setting. Terminal assembled. PID closed-loop setting.
5: Big Jump-start torque: 0.5 Hz/150%
6; Carrier frequency range: 1.0K~15KHz
7: Speed control precision: ± 0.5% the top speed (SVC)
8: Voltage modulate: ( AVR): Can keep output voltage invariableness automatically when the power net and voltage changes.
9: Automatism restrict current: Can restrict the Maximum current of the motor. And can protect the inverter and the motor reliably.
10: PLC program control: Single Cycle, continuous loop, wobble control and are fit for all kinds of filed's demand.
11: Input, output terminal are programmable and convenient for user
12: Can choose analog signals output, voltage and current.
