Question

Can one Inverter be used to drive multiple motors?

Answer

Yes. Make the settings under the following condition:

Inverter rated current ≥ Motor rated current × 1.1 (at continuous operation)

Check whether the current is within the Inverter's overload capacity at maximum load. Electronic thermal relays cannot be used, so install a protective thermal relay for each motor.
