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.
