8 USING A LINEAR SERVO MOTOR
8.2 Startup
■
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 servo motor speed (in the positive and negative directions) at that time with MR Configurator2.
3.
The servo motor speed is a positive value when [Pr. PC27.0 Encoder pulse count polarity selection] is set to "0" (encoder
pulse increasing direction in the servo motor CCW or positive direction), the positive direction of the linear servo motor
matches the increasing direction of the linear encoder, and the linear servo motor is operated in the positive direction. If
the positive direction of the linear servo motor does not match the increasing direction of the linear encoder, the servo
motor speed will be a negative value. The servo motor speed is a negative value when [Pr. PC27.0 Encoder pulse count
polarity selection] is set to "1" (encoder pulse decreasing direction in the servo motor CCW or positive direction), the
positive direction of the linear servo motor matches the increasing direction of the linear encoder, and the linear servo
motor is operated in the positive direction.
