WANT FORWARD OPERATION WHEN SWITCH IS CLOSED AND STOP WHEN SWITCH OPENS TO CONTROLL AIR COMPRESSOR. SWITCH WIRED TO DI 4 AND COM TERMINALS. WHAT PARAMETERS DO I CHANGE TO MAKE DI4 AND COM CONTROLL MOTOR NOT PANEL?

Answer This Question

The default is DI1 port (P01.02=1). If DI4 is required, modify P01.02=1, P05.03=1.

I plan to use this VFD to run a 3-phase fan. If there is a power outage, can this VFD automatically start back by itself or must somebody push a start button?

Answer This Question

Generally, by default, you need to press the run button. If you want it to start automatically, you need to set parameters and wiring.

I have a 3 phase 10 hp poly phase motor and I only have 220 volt single phase available,will this work for my application,how ls it wired

Answer This Question

The power supply may be insufficient. If the motor power is smaller or the load is small, it is okay, but it will be more difficult to provide sufficient power.

I have a air compressor with a 10hp 3ph motor but only have 1ph input will this work for starting and running

Answer This Question

If it is a 220V three-phase asynchronous motor, it is ok, but please note that the power cord must be thick enough, otherwise the power cord will heat up or the voltage drop will be too large. Pay attention to measuring the voltage of the 220V power supply screw of the inverter during work.

The unit shows a single wire 220 input with a neutral, I only have 2 wire 220 with ground. It's single phase 110v per leg, can I connect one leg to line, and the other to neutral? Am I able to use this? Is that a common ground for input and output on the right side? The manual shows rst, but the unit shows LN.

Answer This Question

If yours is three-phase 220V, then connect two live wires to L N, and there is 220V between the two live wires.
