3G3RV omron inverter

[zakir]

is it possible to run more than one motor by using omron 3G3RV inverter?

if yes how please?

I know nothing about that particular inverter. But if a 3 phase then

Hook motors in parallel on VFD output - all 3 phase of course and all the same voltage and best if all the same size.
VFD must equal (Kw) the total of all motors Kw
The VFD has overcurrent but that is for TOTAL load
- not each motor-
each motor should have overcurrent protection and some means of disconnecting it if overloaded. In my mind each overload would have a switch that would tell VFD to stop and also set an alarm light to know there is a problem.

All motors must start together - you cannot add motors to running VFD and motors.

One thing to watch out for is how long the cables are between motor and VFD. READ the VFD factory manual.

Do NOT run the motors too slow say below 10 or 5 Hz the motor fan may / will not run fast enough to cool the motor.

I think that should cover basics.
