„ Setting the Zero Point for a Finite Length Mode Axis
Set the zero point as described here 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
Mode Axis.
* 1. The OL††06 value must be saved when it is set.
* 2. See the information on the next page for more details on saving the
OL††06 value.
* 3. Execute with the ZSET command.
YES
NO
Start
Servo ON
JOG to move close
to the zero point.
STEP to move to
the zero point.
Repeat for every axis.
OL 06 = -(IL 02) + OL 06 *1
Save OL 06 *2
Has the setting for the required
axis been completed?
Set the zero point *3
