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. PC27.0 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 setting method
1.
Confirm the positive direction of the linear servo motor. [Pr. PA14] determines the relation of the travel direction of the
linear servo motor under commands. Refer to the following table.
The positive and negative directions of the linear servo motor are 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. PC27.0
Encoder pulse count polarity selection] to "0" (encoder pulse increasing direction in the servo motor CCW or positive
direction). If the positive direction of the linear servo motor does not match the increasing direction of the linear encoder,
set [Pr. PC27.0] to "1" (encoder pulse decreasing direction in the servo motor CCW or positive direction).
