N
of the drive. (U
N
refers to the highest voltage in each nominal voltage
range, that is 480 V AC for ACL30-04).
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).
99.04 MOT NOM VOLTAGE
• Motor nominal frequency
Range: 5.0…500.0 Hz.
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.
99.05 MOT NOM FREQ
• Motor nominal speed
Range: 0…30000 rpm.
99.06 MOT NOM SPEED
• Motor nominal power
Range: 0.00…10000.00 kW.
99.07 MOT NOM POWER
• Motor nominal cos
ϕ
(not applicable to permanent
magnet motors). This value can be set for better
DTC control accuracy. If the value is not given by
the motor manufacturer, use value 0 (ie, default
value).
Range: 0.00…1.00.
99.08 MOT NOM COSFII
• Motor nominal shaft torque. This value can be set
for better DTC control accuracy. If the value is not
given by the motor manufacturer, use value 0 (ie,
default value).
Range: 0.000…2147483.647 N•m.
99.09 MOT NOM TORQUE
After setting the motor parameters, drive generates
the alarm ID-RUN to inform that the you need to
perform the ID run.
