• motor nominal voltage
Allowed range: 1/6 × U
to the highest voltage in each nominal voltage range).
With permanent magnet motors: The nominal voltage is
the BackEMF voltage (at motor nominal speed). If the
voltage is given as voltage per rpm, e.g. 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).
• motor nominal frequency
Range: 5...500 Hz. With multimotor drives, see page 16.
With permanent magnet motor: If the frequency is not
given on the motor nameplate, it has to be calculated with
the following formula:
f = n × p / 60
where p = number of pole pairs, n = motor nominal speed.
• motor nominal speed
Range: 0...10000 rpm. With multimotor drives, see
page 16.
• motor nominal power
Range: 0...10000 kW. With multimotor drives, see
page 16.

control accuracy. If value is not given by the motor
manufacturer, use value 0 (i.e. default value).
Range: 0...1.
• motor nominal shaft torque. This value can be set for
better DTC control accuracy. If value is not given by the
motor manufacturer, use value 0 (i.e. default value).

After the motor parameters have been set, alarm ID-RUN
is generated to inform that the ID run needs to be
performed.
