14. USING A LINEAR SERVO MOTOR

14 - 22

14.3.5 Operation from controller

The linear servo can be used with any of the following controllers.

Servo system controller Model

Motion controller Q17_DSCPU

Simple motion module QD77MS_

(1) Operation method

For the system using the incremental linear encoder, the magnetic pole detection is automatically

performed at the first servo-on after the power-on. For this reason, when performing the positioning

operation, create the sequence which surely confirms the servo-on status as the inter lock condition of

the positioning command.

Also, some parameter settings and the home position return type differ according to the controller type.

(2) Servo system controller setting

(a) Setting precautions

The following parameters will be enabled by turning the servo amplifier power off and on again after

the controller writes the parameters to the servo amplifier.
