Info
Selection of the motor control type.
This control mode is used for servo control of a synchronous motor.
4Servo control for synchronous motor (SC-PSM)
A motor encoder must be connected to the inverter. This motor encoder
serves as a feedback system for engine control.
This control mode is used for servo control of an asynchronous motor.
4Servo control for asynchronous motor (SC-ASM)
A motor encoder must be connected to the inverter. This motor encoder
is used as a feedback system for the motor control.
This control type is used for the sensorless control of a synchronous
motor.
• Control mode is possible up to a rated power of 22 kW.
4Sensorless control for synchronous motor (SL-PSM)
This control type is used for sensorless vector control of an asynchro-
nous motor.
This control mode is used for the speed control of an asynchronous
motor via a V/f characteristic and is the simplest control mode.
