14. USING A LINEAR SERVO MOTOR
(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 cycling the servo amplifier power after the controller
writes the parameters to the servo amplifier.
