of the nominal voltage range, ie, 480 V AC for ACSM1-04).
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).
- motor nominal frequency
Range: 5...500 Hz. With multimotor drives, see section
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 section
page 19.
- motor nominal power
Range: 0...10000 kW. With multimotor drives, see section
page 19.
- motor nominal cos
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).
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).
Range: 0...2147483.647 Nm.
After the motor parameters have been set, alarm ID-RUN is generated
to inform that the motor ID run needs to be performed.
