P1-07 Rated motor voltage

Setting range:

• 230 V inverter: 20 – 230 − 250 V
• 400 V inverter: 20 – 400/460460 V American version only – 500 V
• 575 V inverter: 20 – 575 – 600 V

Specifies the nominal voltage of the motor connected to the inverter (in accordance with the motor nameplate). The parameter value is used in V/f speed control for controlling the output voltage applied to the motor. In V/f speed control, the output voltage of the inverter amounts to the value set in P1-07 if the output speed corresponds to the motor base frequency set in P1-09.

"0V" = DC link compensation is disabled. When braking, the V/f ratio shifts as a result of the voltage increase in the DC link, resulting in greater motor losses. The motor heats up more. The additional motor losses during braking might make a braking resistor redundant.
