Goals and Symptoms

A customer's main power supply is 380Vac, and his motor nominal voltage is 440Vac. Could the motor output voltage also reache to 440Vac at nominal speed if "Uns" is set to 440? Is there any problem of this setting?

Causes and Fixes

It's not possible for the inverter to provide a output voltage upper to the main supply ( lower possible ). So in your case you can try to supply the motor under 380 V, you will obtain instability but depend to the application.
