9.2 Setting Procedure of Absolute Position Detection Function

This section explains the procedure for setting the Absolute Position Detection Function.

9.2.1 System Startup Flowchart

Start up the system using the following procedure.

* If the system does not satisfy the conditions described in 9.4.1 ( 2 ) Conditions to Enable the Simple Absolute Infinite

Axis Position Control when using the axis as an infinite length axis, the Machine Controller carries out the operation
without using simple absolute length position control.

After the steps 2 to 4 described above are successfully completed, the absolute position detection system will be ready
for operation.

Always perform the startup procedure of the absolute position detection system in the following situations.

• When starting up the absolute position detection system for the first time
• When the Servomotor is changed
• When an absolute encoder-related alarm occurs

1

Check Devices

Check to see if the SERVOPACK, Servomotor, and cables are the right products and models for the absolute encoder.

2

Initialize the Absolute Encoder

Follow the setup procedure to set the absolute encoder to default values.

9.2.2 Initializing the Absolute Encoder, and Appendix C Initializing the Absolute Encoder)

Setting Parameters Related to the Machine Controller and the SERVOPACKs

Set all parameters related to the Absolute Position Detection Function of the Machine Controller and SERVOPACKs.
The setting procedure for a finite length axis is different from that for an infinite length axis.

Zero Point Setting

Set the zero point as well as the absolute zero point, that is, the machine coordinate zero point.
