Setting the Origin of the Absolute Linear Encoder

You can set any position as the origin in the following Linear Encoders.
• Mitutoyo Corporation
ABS ST780A Series or ST1300 Series
Models: ABS ST78A/ST78AL/ST13
• Renishaw PLC
EVOLUTE Series
Models: EL36Y-
• Renishaw PLC
RESOLUTE Series
Models: RL36Y-
1. After you set the origin, the /S-RDY (Servo Ready) signal will become inactive because the
system position data was changed. Always turn the SERVOPACK power supply OFF and ON
again.
Important
2. After you set the origin, the Servomotor phase data in the SERVOPACK will be discarded. If
you are using a Linear Servomotor without a Polarity Sensor, execute polarity detection again
to save the Servomotor phase data in the SERVOPACK.
Preparations
Always check the following before you set the origin of an absolute encoder.
• The parameters must not be write prohibited.
• The servo must be OFF.
