Hi,

 is there any limitation for motor to connect in parallel with g120 drive

The principle limiter for this application will be the cable length. The maximum cable length for the single converter will be defined in the catalogue.

As the converter / inverter cannot provide I2t protection for each motor, then thermal overloads will be required for the supply line to each motor.

For example, for a 200 Metre cable length supported by the inverter drive, for qty 10 motors the maximum cable length for each motor will be 20 Metres.
