284 Parameters
99.04 MOT NOM
VOLTAGE
Defines the nominal motor voltage. Nominal voltage
is a fundamental phase to phase rms voltage, which
is supplied to the motor at the nominal operating
point. This parameter value must be equal to the
value on the asynchronous motor name plate.
Note:
• Make sure the motor is connected correctly (star
or delta) in accordance with the rating plate.
• With permanent magnet motors, the nominal
voltage is the BackEMF voltage (at motor 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. Note that the
nominal voltage is not equal to the equivalent DC
motor voltage (E.D.C.M.) value given by some
motor manufactures. The nominal voltage can be
calculated by dividing the E.D.C.M. voltage by 1.7
(= square root of 3).
• 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.
• This parameter cannot be changed while the drive
is running.

99.05 MOT NOM FREQ
Defines the nominal motor frequency.
Note: This parameter cannot be changed while the
drive is running.
- / Real
5.0…500.0 Hz Nominal motor frequency. - / 10 = 1 Hz
99.06 MOT NOM SPEED
Defines the nominal motor speed. Must be equal to
the value on the motor rating plate. When the
parameter value is changed, check the speed limits
in parameter group 20 LIMITS.
Note: This parameter cannot be changed while the
drive is running.
