MOTOR CONTROL PARAMETERS
P3.1.2.1 CONTROL MODE (ID 600)
Use this parameter to set the AC drive control mode.
Selection

Selection name
Description
0
Frequency control
The frequency reference of the drive is set to the output fre-
quency without slip compensation. The actual speed of the
motor is specified by the motor load.
1
Speed control
The frequency reference of the drive is set to the motor
speed reference. The motor load does not have an effect on
the motor speed. There is slip compensation.
2
Torque control
The motor torque is controlled. The motor produces torque
in the set speed limits to achieve torque reference. P3.3.2.7
(Torque Control Frequency Limit) controls the motor speed
limit.
P3.1.2.2 MOTOR TYPE (ID 650)
Use this parameter to set the type of motor in your process.

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.
