P3.1.2.1 CONTROL MODE (ID 600)
Selection
number
Selection name Description
0 Frequency control (open loop)
The frequency reference of the drive is set to the output
frequency without slip compensation. The actual speed of the
motor is specified by the motor load.
1
Speed control (sensorless
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 (open loop)
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)
In this parameter, you can 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.
When this parameter changes, parameters P3.1.4.2 and P3.1.4.3 start automatically. The 2
parameters have different values for each motor type.

P3.1.2.4 IDENTIFICATION (ID 631)
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. The goal is to
find the parameter values that are optimal for the operation of the drive.
NOTE!
Before you do the identification run, you have to set the motor nameplate
parameters.
