2ND REFERENCE POINT
—
REACHED, nTH AXIS
[Function]
This signal indicates that the axial component of the nth axis is ON the 2nd reference point.
This signal is available per control axis, and the last number of the signal abbreviation indicates the
control axis No.
ZP2n
1 : 2nd reference point reached, 1st axis
2 : 2nd reference point reached, 2nd axis
:
14 : 2nd reference point reached, 14th axis
[Operation]
(1) The signal turns ON when:
• 2nd reference point reached is attained with G30 command in automatic operation.
(Note) If 2nd reference point reached is achieved in other operation mode, or by other command,
the signal does not turn ON.
(2) The signal turns OFF when:
• The axial component in position is relocated from the 2nd reference point by motion
command.
• "Emergency stop" signal is input or servo alarm occurs, causing stop to the machine.
