13 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 Function Default
Value
When ena-
bled
No. Dig.
Pn080 Application Function Selections 80 - -
0 Polarity Sensor Selection 0 After restart
0 Use polarity sensor.
1 Do not use polarity sensor.
Pn081 Application Function Selections 81 - -
3 Hall Sensor Signal Inversion
0 Does not inverse the signals (Pos-
Logic)
0 After restart
1 Inverses the signals (Neg-Logic)
Parameter Setting
Positive logic Pn080.0 = 0
Pn081.3 = 0
Pn080.0 = 0
Pn081.3 = 1
Pn080.0 = 1
Pn081.3 = 0
Negative logic
Available
Not available
Hall Sensor Hall Sensor Signal 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.
