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 or ST1300 Series
Models: ABS ST78A/ST78AL/ST13
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.
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 to set the origin of an absolute linear encoder.
1.
Click the Servo Drive Button in the workspace of the Main Window of the SigmaWin+.
2. Select Set Origin in the Menu Dialog Box.
The Set Origin Dialog Box will be displayed.
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.
