9905 MOTOR NOM
VOLT
Defines the nominal motor voltage. Must be equal to the
value on the motor rating plate. 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! Never connect a motor to a drive which
is connected to power line with voltage level higher
than the rated motor voltage.
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.

Note: The stress on the motor insulations is always
dependent on the drive supply voltage. This also applies to
the case where the motor voltage rating is lower than the
rating of the drive and the supply of the drive.
