10.2.2 MOTOR CONTROL PARAMETERS
P3.1.2.2 MOTOR TYPE (ID 650)
Use this parameter to set the type of motor in your process.
Selection
number
Selection name Description
0 Induction motor (IM) Make this selection if you use an induction motor.
1 Permanent Magnet Motor (PM) Make this selection if you use a permanent magnet motor.
2 Reluctance Motor Make this selection if you use a reluctance motor.
When you change the value of parameter P3.1.2.2 Motor Type, the values of parameters
P3.1.4.2 Field Weakening Point Frequency and P3.1.4.3 Voltage at Field Weakening Point
change automatically, as the table below shows. The 2 parameters have different values for
each motor type.
Parameter
Induction motor (IM) Permanent magnet motor (PM)
P3.1.4.2 (Field Weakening Point
Frequency)
Motor nominal frequency
Internally calculated
P3.1.4.3 (Voltage at Field Weaken-
ing Point)
100.0%
Internally calculated
P3.1.2.3 SWITCHING FREQUENCY (ID 601)
Use this parameter to set the switching frequency of the AC drive.
If you increase the switching frequency, the capacity of the AC drive reduces. To reduce
capacitive currents in the motor cable, when the cable is long, we recommend that you use a
low switching frequency. To reduce the motor noise, use a high switching frequency.
P3.1.2.4 IDENTIFICATION (ID 631)
Use this parameter to find the parameter values that are optimal for the operation of the
drive.
The identification run calculates or measures the motor parameters that are necessary for a
good control of the motor and speed.
The identification run helps you to adjust the motor-specific and the drive-specific
parameters. It is a tool for the commissioning and the servicing of the drive.
NOTE!
Before you do the identification run, you have to set the motor nameplate
parameters.
