15. USING A LINEAR SERVO MOTOR
15 - 24
15.3.6 Absolute position detection system
When the linear servo motor is used with the absolute position detection system, an absolute position linear
encoder is required.
(1) Operating conditions of absolute position detection system
(a) Use an absolute type linear encoder.
(b) Perform the magnetic pole detection in the incremental system and disable the magnetic pole
detection after the detection.
(c) Enable the absolute position detection system with [Pr. PA03 Absolute position detection system].
(2) Alarm detection
[AL. 25 Absolute position erased], [AL. 92 Battery cable disconnection warning], [AL. 9F Battery
warning], and [AL. E3 Absolute position counter warning] are not provided for the linear servo motor.
(3) Backup
The linear encoder backs up the absolute position data. Therefore, the encoder battery need not be
installed to the servo amplifier.
(4) Absolute position data transfer to controller
Refer to section 12.8 for absolute position data transfer to the controller.
