3.6 P-## Motor Data

Parameter group related to setting motor data in the drive.
3.6.1 P-0# Motor Data
3 3
Parameters to configure Motor, Auto Tuning and Slip
Compensation.
P-01 Motor Poles
Range:
4 [2 - 100]
*
Poles ~n @ 50 Hz
n
2 2700–2880
4 1350–1450
6 700–960
Table 3.13 Pole Number for Normal Speed Ranges
Table 3.13 shows the pole number for normal speed ranges
of various motor types. Define motors designed for other
frequencies separately. The motor pole value is always an
even number, because it refers to the total pole number,
not pairs of poles. The frequency converter creates the
initial setting of parameter P-01 Motor Poles based on
parameter F-04 Base Frequency and parameter P-06 Base
Speed.
P-02 Motor Power [HP]
Range:
4.00 [0.09 -

P-03 Motor Current
Range:

P-04 Auto Tune
Option:
58
Function:
Enter the number of motor poles.
~n @ 60 Hz
n
3250–3460
1625–1730
840–1153
Function:
Enter the nominal motor power in hp
according to the motor nameplate data. The
default value corresponds to the nominal
rated output of the unit. This parameter is
visible in keypad if parameter K-03 Regional
Settings is [1] US.
Function:
Enter the nominal motor current value
from the motor nameplate data. The
data are used for calculating torque,
motor overload protection, and so on.
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
The Auto Tune function optimizes dynamic
motor performance by automatically optimizing
the advanced motor parameters
(parameter P-30 Stator Resistance (Rs) to
P-04 Auto Tune
Option:
[0] Off

[1] Full Auto
Tune
[2] Reduced
Auto
Tune
NOTICE
•
For the best results run Auto Tune on a cold
motor.
•
Auto Tune cannot be performed while the
motor is running.
•
Auto Tune cannot run with a sine-wave filter
connected.
NOTICE
It is important to set motor parameters F-04, F-05, and
P-02 to P-08 correctly, since these form part of the Auto
Tune algorithm. Perform an Auto Tune to achieve
optimum dynamic motor performance. It may take up to
10 minutes, depending on the power rating of the
motor.
NOTICE
Avoid generating external torque during Auto Tune.
NOTICE
If 1 of the settings in parameters F-04, F-05, or P-02 to
P-08 is changed, parameter P-30 Stator Resistance (Rs) to
parameter P-01 Motor Poles, the advanced motor
parameters, return to default setting.

Function:
parameter P-35 Main Reactance (Xh)) at motor
standstill.
Activate the Auto Tune function by pressing
[Hand] after selecting Enable Complete AMA or
[2] Reduced Auto Tune. After a normal sequence,
the display reads: Press [OK] to finish Auto Tune.
After pressing [OK], the frequency converter is
ready for operation.
