NEAR 1ST REFERENCE
—
POINT nTH AXIS
[Function]
This signal indicates that the control axis is near the 1st reference point in the absolute position
detection system.
[Operation]
This signal turns ON when the control axis is in the range of the parameter set using the 1st
reference point as a base point, and turns OFF when the range is exceeded. The parameter is set
with #2057 (nrefp) and #2058 (nrefn) in the [ABS. POSI PARAM] screen.
+ direction
Near 1st reference
point (NRFn)
(Note 1) "Near 1st reference point" signal is output even while the axis is moving, but there may be
a slight deviation with the actual machine position.
Rapid traverse : Approx. 19mm at 20m/min.
Cutting feed
Note that this signal may not be output when the setting value is too small.
(Note 2) This signal is valid only with the absolute position detection system.
(Note 3) When 0 is set for #2057 (nrefp) and #2058 (nrefn) in the [ABS. POSI PARAM] screen, it
will be same as when the grid width is set.
