VOLT Defines the motor nominal voltage.
• For AM, nominal voltage is the value displayed on
the motor name plate.
• For PMSM, nominal voltage is back emf voltage at
nominal speed.
The inverter cannot supply the motor with a voltage
greater than the input voltage.
Note : The output voltage is not limited by the nominal
motor voltage, but increases linearly up to the value of
the input voltage.
Motor nominal voltage plot
Warning! The stress on the motor insulations
depends on the inverter supply voltage. This
also applies when the motor voltage rating is
lower than the inverter rating and the supply voltage of
the inverter.
The rms voltage can be limited to the motor nominal
voltage by setting the maximum frequency of the
inverter in parameter 2008 to the motor nominal
frequency.
