3.6 P-## Motor Data

Parameter group related to setting motor data in the drive.
3.6.1 P-0# Motor Data
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
The table shows the number of poles 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 number of poles, not pairs of poles. The frequency converter creates the initial setting of par.
P-01 Motor Poles based on par. F-04 Base Frequency and par. P-06 Base Speed.
P-02 Motor Power [HP]
Range:
4.00 hp* [0.09 - 3000.00 hp]
P-03 Motor Current
Range:
7.20 A* [0.10 - 10000.00 A]
P-04 Auto Tune
Option:
[0] * Off
[1] Enable complete Auto Tune
[2] Enable reduced Auto Tune
Note:
• For the best results run Auto Tune on a cold motor.
• Auto Tune cannot be performed while the motor is running.
• Auto Tune cannot be performed on permanent magnet motors.

3250 - 3460
1625 - 1730
840 - 1153
Function:
Enter the nominal motor power in HP according to the motor nameplate data. The default value corre-
sponds to the nominal rated output of the unit. This parameter is visible in Keypad if par. K-03 Regional
Settings is US [1]
Function:
Enter the nominal motor current value from the motor nameplate data. The data are used for calculating
torque, motor protection etc.
Function:
The Auto Tune function optimises dynamic motor performance by automatically optimising the advanced
motor parameters (par. P-30 Stator Resistance (Rs) to par. P-35 Main Reactance (Xh)) at motor standstill.
Activate the Auto Tune function by pressing [Hand] after selecting [1] or [2]. See also the section Auto
Tuning in the AF-650 GP Design Guide. After a normal sequence, the display will read: "Press [OK] to finish
Auto Tune". After pressing the [OK] key the frequency converter is ready for operation.
This parameter cannot be adjusted while the motor is running.
