Motor Data
P.040 Motor rated curr
(Motor rated current)
Rated current [A
rms
] of the motor at rated kilowatt/horsepower and voltage (given on the nameplate, see figure
7.6.3).
In case of control with multiple motors, enter a value equal to the sum of the rated currents of all the motors.
Do not perform any self tune.
P.041 Motor pole pairs
Pole pairs of the motor. The setting of this data, can be easily calculated with the following formula:
N[rpm] =
60 [s] x f [Hz]
2p [polepairs]
3 kW
Motor: 3 phase
1420 rpm

Figure 7.6.3: Motor Nameplate (Example: kW rating for 400V motor and Hp rating for 575V motor)
Example: calculation of the pole pairs of a motor having the data shown in the above label:
p [polepairs] =
=
= 2
60 [s] x f [Hz]
n [rpm]
N
60 [s] x 60 [Hz]
1750 [rpm]
the value to set in the parameter
P.041
is "2".
Where: p = motor pole pairs; f = rated motor frequency (
P.062
); n
N
= rated motor speed (see figure 7.6.3)
P.042 Motor power fact
(Motor power factor)
Motor power factor (given on the nameplate, see figure 7.6.3).
A signalling of the "negative power factor" condition is available on the digital output as "
Neg pwr fact
".
P.043 Motor stator R
(Motor stator Resistance)
Measurements of the stator resistance of the motor.
This value will be automatically updated, after performing the self tune procedure.
