ST600s | Several motors on one frequency inverter

Can several motors be operated on only one frequency inverter?

Yes, this is possible if the following rules are observed:

The motors must have the same values (be identical in construction).

The frequency inverter must be operated in V/f mode.

The maximum total cable length specified in the relevant user manual for the frequency inverter must not be exceeded.

In all cases, an output filter is recommended to extend the maximum allowable motor cable length by 50%.

Each motor should be protected by its own thermal overload protection.

The power of the frequency converter should be selected based on the total motor current required by adding the rated current of all connected motors and selecting a frequency converter with sufficient rated output current capacity.

The motors must be permanently connected to the inverter and must not be able to be started or stopped individually while the inverter is activated.
