Selecon of the motor control type.
1 Servoregelung (SC-PSM) This control mode is used for servo control of a synchronous motor.
4Servo control for synchronous motor (SC-PSM) ^ 235
A motor encoder must be connected to the inverter. This motor encoder
serves as a feedback system for engine control.
2 Servo control (SC ASM) This control mode is used for servo control of an asynchronous motor.
4Ser
vo control for asynchronous motor (SC-ASM)^ 236
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
mot
or.
•
Control mode is possible up to a rated power of 22 kW.

6 V/f characterisc control (VFC open loop) This control mode is used for the speed control of an asynchronous
motor via a V/f characterisc and is the simplest control mode.
