7.3 Using an Absolute Encoder
7 -13
The following methods are used to save the Zero Point Position Offset (OLxx06).
1.
Saving in a Ladder Logic Program M Register
Calculate (−(calculated position monitored in the machine coordinate system) + the Zero Point Position Off-
set setting) and save the results in the M register when they are stored at OLxx06.
Always store the contents saved in M register at setting parameter OLxx06: Zero Point Offset.
Ladder Logic Program Required for a Finite Length Mode Axis: ABS System Finite Length Mode Axis
(Axis No. 1)
Zero Point Setting signal startup detection
Zero point position offset − calculated position monitor in the machine
coordinate system is stored in OLxx06.
Save in M register.
Store the offset saved in M register in OLxx06.

2.
Saving the OLxx06: Zero Point Offset from the CP-717 Parameter Screen
After the zero point and the Zero Point Offset (OLxx06) value (current value) are set, use SAVE to save the
settings in the Controller. When power is turned back ON, the value that was saved for Zero Point Offset
(OLxx06) will be stored automatically.
