Example: When Setting the Current Machine Coordinate Position to “0”
during Zero-point Setting Execution:
Set 0 into OLxx06
Procedure for Setting a Zero-point for a Linear Axis
After executing absolute encoder initialization, set the machine coordinate
zero-point and create the machine coordinate system by executing zero-point
setting.
The operating procedure for executing zero-point setting in a linear axis is
shown below:
*1 The OLxx06 value must be saved at the same time as setting OLxx6.
*2 See the following supplemental item on saving OLxx06.
*3 Execute with the ZSET command.
Start
Servo ON
Move to zero point in
STEP operation
OLxx06=-(ILxx02)+OLxx06
∗1
Preserve OLxx06 *2
End
Move next to zero point
in JOG operation
Execute Zero
Point Setting *3
