Using an Absolute Encoder
7-15
( 3 ) Setting the Zero Point for a Finite Length Axis
Set the zero point after initializing the absolute encoder to set the zero point of the machine
coordinate system and to establish the machine coordinate system.
The following illustration shows the procedure for setting the zero point for a finite length axis.
* 1. The OL
48 value must be saved when it is set.
* 2. See the information on the next page for more details on saving the OL
48 value.
* 3. Execute with the ZSET command.
Repeat for every axis.
Start
Servo ON
STEP to move to the
zero point.
OL48 = OL48 - IL10
Save OL48.
*2
End
JOG to move close to
the zero point.
YES
NO
Set the zero point.
*3
*1
Has the setting for the required
axis been completed?
