Absolute position detection system

When the linear servo motor is used with the absolute position detection system, an absolute position linear encoder is
required.
Operating conditions of absolute position detection system
• Use an absolute position type linear encoder.
• Perform magnetic pole detection in the incremental system, and disable magnetic pole detection after detection.
• Enable the absolute position detection system with [Pr. PA03 Absolute position detection system].
Alarm detection
[AL. 025 Absolute position erased], [AL. 092 Battery cable disconnection warning], [AL. 09F Battery warning], and [AL. 0E3
Absolute position counter warning] are not detected.
Backup
The linear encoder backs up the absolute position data. Therefore, the encoder battery need not be installed to the servo
amplifier.
