Motor control mode

The inverter supports different modes for closed-loop/open-loop motor control.

Setting can only be changed if the inverter is disabled.
 
Selection of the motor control mode.
2
Servo control (SC ASM)  
This control mode is used for servo control of an asynchronous motor.
A motor encoder must be connected to the inverter. This motor encoder is used as a feedback system for the motor control.
3
Sensorless control (SL PSM)  
This control type is used for the sensorless control of a synchronous motor.
4
Sensorless vector control (SLVC)
This control type is used for sensorless vector control of an asynchronous motor.
6
V/f characteristic control (VFC open loop)
This control mode is used for the speed control of an asynchronous motor via a V/f characteristic and is the simplest control mode.
7
V/f characteristic control (VFC closed loop)  
The control mode is used for speed control of an asynchronous motor via a V/f characteristic with speed feedback.
A motor encoder must be connected to the inverter. This motor encoder is used as a feedback system for the motor control.
8
Sensorless control for synchronous motors (SLSM-PSM)  
This control type is used for the sensorless control of a synchronous motor.
Note!
This control mode is not available in the version with network IO-Link!
Compared to the sensorless "SL-PSM" control, the "SLSM-PSM" control offers the following advantages:
–
Lower power consumption and more torque through HF injection in the lower speed range
 
–
Easier commissioning due to support for automatic identification of the motor
 
 
The detailed description of each motor control type can be found in the chapter "Configuring the motor control".
