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 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.
The positive and negative directions of the linear servo motor are as follows.
2.
Confirm 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" (Linear servo motor positive direction and linear encoder increasing
direction). If the positive direction of the linear servo motor does not match the increasing direction of the linear encoder,
set [Pr. PC45.0] to "1" (Linear servo motor positive direction and linear encoder decreasing direction).
