Setting
Setting of linear servo motor series and linear servo motor type
Set the linear servo motor series and linear servo motor type with [Pr. PA17 Servo motor series setting] and [Pr. PA18 Servo
motor type setting].
Setting of linear encoder direction and linear servo motor direction
Set [Pr. PC45.0 Encoder pulse count polarity selection] so that the positive direction of the linear servo motor matches the
increasing direction of the linear encoder feedback.
Servo parameter
PC45.0
■Servo parameter setting method
1.
Confirm the positive direction of the linear servo motor. [Pr. PA14 Travel direction selection] determines the relation of the
travel direction of the linear servo motor under commands as follows.

2.
Check the increasing direction of the linear encoder.
3.
If the positive direction of the linear servo motor matches the increasing direction of the linear encoder, set [Pr. PC45.0
Encoder pulse count polarity selection] to "0" (encoder pulse increasing direction in the servo motor CCW or positive
direction). If the count directions of linear servo motor and linear encoder do not match, set [Pr. PC45.0] to "1" (encoder
pulse decreasing direction in the servo motor CCW or positive direction).
Description
Encoder pulse count polarity selection
0: Encoder pulse increasing direction in the servo motor CCW or positive direction
1: Encoder pulse decreasing direction in the servo motor CCW or positive direction
Initial value: 0 (encoder pulse increasing direction in the servo motor CCW or positive direction)
