2.3 Notes
(1) PMC axis control
The reference point establishment operation is not executed by the rapid traverse (axis
control command 00h) and the JOG feed (axis control command 06h) of PMC axis control.
(2) Rapid traverse operation by command other than G00
The reference point establishment operation is not executed by the rapid traverse
operation automatically generated with the command in the fixed cycle, etc.
(3) Reference point establishment operation
The specification of reference point establishment by detecting some reference marks is
compatible with the past one. The limitations and parameter setting method etc. are also
the same as past specifications. Please refer to "FANUC Series 16/18/16i/18i/21i distance
coded linear scale interface specifications (A-61209)" for details.

  • Page 21. Outline Intervals of reference marks of distance coded linear scale are variable. That is, if CNC can know the interval of reference marks, it can know an absolute position on the scale. When the axis is moved by G00 command or JOG mode, this function establishes the reference point by measuring

For instance, when the reference point of X axis has been established, and the reference points of Y and Z axis have not been established yet, and
  • Page 62.1.2.2 Absolute command and incremental command As described in Item 2.1.2 (4), the axis is positioned to the commanded end point after the reference point is established. The operation at this time is as follows. (1) When an absolute command is specified The axis moves to the end point in the new
  • Page 7(2) When an Incremental command is specified Each axis moves only by the commanded distance. That is, the behavior of the axis is shown on a bold line in the figure below. However, the figure shows each position, and it does not show an actual tool path. The coordinate value of the end point becomes

And the reference point establishment operation is not restated in this block. The reference point establishment operation
