14. USING A LINEAR SERVO MOTOR
14 - 8
(3) Settings of the linear encoder direction and the linear servo motor direction
Set the first digit of [Pr. PC27] (Encoder pulse count polarity selection) so that the positive direction of
the linear servo motor matches with the increasing direction of the linear encoder feedback.
[Pr. PC27]
Encoder pulse count polarity selection
0: Linear servo motor positive direction and linear encoder increasing direction
1: Linear servo motor positive direction and linear encoder decreasing direction
(a) 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 as shown below.

2) Confirm the increasing direction of the linear encoder.
3) If the positive direction of the linear servo motor matches with the increasing direction of the
linear encoder, set [Pr. PC27] to "_ _ _ 0". If the positive direction of the linear servo motor does
not match with the increasing direction of the linear encoder, set [Pr. PC27] to "_ _ _ 1".
(b) Confirmation method
Confirm the positive direction of the linear servo motor and the increasing direction of the linear
encoder in the following procedure.
1) In servo-off status, move the linear servo motor in the positive direction manually.
2) Confirm the motor speed (in the positive and negative directions) at that time with MR
Configurator2.
