5.18 Setting the Origin of the Absolute Encoder
5.18.1 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
Models: ABS ST78A/ST78AL
Preparations
The following conditions must be met to set the origin of the absolute linear encoder.
• The parameters must not be write prohibited.
• The servo must be OFF.
Applicable Tools
The following table lists the tools that you can use to set the origin of the absolute linear
encoder and the applicable tool functions.
Operating Procedure
Use the following procedure.
1. Select Setup - Set Origin from the menu bar of the Main Window of the SigmaWin+.
Click the Cancel Button to cancel setting the origin of the absolute linear encoder. The Main Window
will return.
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.
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.
