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
PC27.0
■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.
Setting value of [Pr. PA14]
0
1
The positive and negative directions of the linear servo motor are as follows.
Negative direction
Positive direction
LM-H3/LM-F series
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. PC27.0
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. PC27.0] to "1" (Linear servo motor positive direction and linear encoder decreasing direction).
