Description
Defines the nominal motor voltage. For asynchronous
motors, must be equal to the value on the motor rating plate.
For permanent magnet synchronous motors, the nominal
voltage is the back emf voltage at nominal speed.
If the voltage is given as voltage per rpm, eg, 60 V per
1000 rpm, the voltage for 3000 rpm nominal speed is
3 · 60 V = 180 V.
The drive cannot supply the motor with a voltage greater
than the input power voltage.
Note that the output voltage is not limited by the nominal
motor voltage but increased linearly up to the value of the
input voltage.

WARNING! The stress on the motor insulations
depends on the drive supply voltage. This applies
also when the motor voltage rating is lower than the rating of
the drive and the supply voltage of the drive. The rms
voltage can be limited to motor nominal voltage by setting
the maximum frequency of the drive (parameter 2008) to the
motor nominal frequency.
Voltage.
Defines the nominal motor current. Must be equal to the
value on the motor rating plate.
Current
Defines the nominal motor frequency, ie, the frequency at
which the output voltage equals the motor nominal voltage:
Field weakening point = Nom. frequency · Supply voltage /
Motor nom. voltage
Frequency
Defines the nominal motor speed. Must be equal to the
value on the motor rating plate.
