The following methods are used to save the Machine Coordinate System Zero Point Offset (OLC006).
• 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 OLC006.
Store the contents saved in M register at setting parameter OLC006: Zero Point Offset
when system or servo power is turned back ON.
Ladder Logic Program Required for a Finite Length Mode Axis: ABS System Finite
Length Mode Axis
• Saving the OLC006: Machine Coordinate System Zero Point Offset from the CP-717
Parameter Screen
After the zero point and the Machine Coordinate System Zero Point Offset (OLC006)
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 Machine Coordinate System Zero
Point Offset (OLC006) will be stored automatically.
