Question

Does G120 support 1 inverter to drag multiple motors? What type of G120 inverter?

Answer 1

G120 supports one inverter to drive multiple motors, but there are certain conditions and restrictions. 

Specifically, a G120 inverter can only drive up to 50 motors at the same time, and all motors need to have the same parameters, such as power, voltage, current, rated speed, etc.

In addition, when the inverter is running, it is not allowed to connect or disconnect any motor, because the surge current generated when connected may cause the inverter to trip, and high voltage may be generated when disconnected and damage the inverter.

Regarding the type of G120 inverter, the G120 inverter is an integrated inverter, which combines the rectifier unit and the inverter unit together. This design makes the G120 inverter easier to select, and there is no need to select the rectifier and inverter units separately.

The G120 inverter is mainly used to realize the speed control of the motor, supporting V/f control and vector control, but not suitable for servo control.

In general, the G120 inverter has certain flexibility and practicality in supporting the driving of multiple motors, but users need to pay attention to the above conditions and limitations when using it to ensure the normal operation of the inverter and the safe use of the motor.

Answer 2

The G120 supports one inverter to drag multiple motors, but the following conditions must be met:

1. The firmware version must be v4.6 or later.

2. A G120 can only drag up to 50 motors at the same time.

3. It is not allowed to connect or disconnect any motor when the inverter is running, because the inrush current generated during access may cause the inverter to trip, and high voltage may be generated and damage the inverter when disconnected.

The G120 inverter is a modular and compact inverter that perfectly meets the application needs of machines and power electronics cabinets with a nominal current of less than or equal to 55A.
