J Setting the Zero Point for a Finite Length Mode Axis
Set the zero point as described here after initializing the absolute encoder in order to set the
zero point of the machine coordinate system and to create the machine coordinate system.
The following illustration shows the procedure for setting the zero point for a Finite Length
Mode Axis.
Start
Servo ON
JOG to move close
to the zero point.
STEP to move to
the zero point.
D OLxx06 = −(ILxx02) + OLxx06 *1
Repeat for every axis.
D Save OLxx06 *2
Set the zero point. *3
Has the setting for the required
axis been completed?
End
YES
NO
* 1. The OLxx06 value must be saved when it is set.
* 2. See the information on the next page for more details on saving the OLxx06 value.
* 3. Execute with the ZSET command.
