„ The following methods are used to save the Zero Point Offset (OL††48).
Method 1: Saving in a M Register with Ladder Program
Subtract the Calculated Position in Machine Coordinate System from the Machine Coordinate System Zero
Point Offset and save the result in an M register when it is stored in setting parameter OL††48.
Store the contents saved in the M register in Zero Point Offset (setting parameter OL††48) when system
or servo power is turned back ON.
Ladder Program Example Required for a Finite Length Axis (Axis 1)
Method 2: Saving the Zero Point Offset (OL††48) from the MPE720 Parameter Window
After the Zero Point Offset (OL††48) is set after setting the zero point, use
Save to save the settings to
the MP2300. When power is turned back ON, the value that was saved for Zero Point Offset (OL††48)
will be stored automatically.
INFO
Rising edge of Zero Point Set signal detected.
