„ The following methods are used to save the Zero Point Offset (OL††06).
• Saving in a Ladder Logic Program M Register
Calculate (-(calculated position monitored in the machine coordinate system) + the Zero Point
Offset) and save the results in the M register when they are stored at OL††06.
Store the contents saved in M register at setting parameter OL††06: Zero Point Offset when sys-
tem or servo power is turned back ON.
Ladder Logic Program Required for a Finite Length Mode Axis: ABS System Finite Length Mode
Axis (Axis No. 1)
• Saving the OL††06: Zero Point Offset from the MPE720 Parameter Window
After the zero point and the Zero Point Offset (OL††06) value (current value) are set, use SAVE
to save the settings to the Controller. When power is turned back ON, the value that was saved for
Zero Point Offset (OL††06) will be stored automatically.
