SERVOPACK with Semi-closed Loop Control for Linear Motors
This chapter describes the linear drives common in semi-closed loop.
13.1 Magnetic Pole
For driving linear motors, the magnetic pole should be coordinated. The parameters in
the following table are used for that.

Parameter Setting
In case the hall sensor is not available refer to SERVOPACK for Linear
Motors.
13.2 Motor Rotation Direction
The relationship between feedback position and motor magnetic pole position is
dependent on the mounted conditions. So, the parameters below are used for the coordi-
nation.
