1320 Coordinate value I of stored stroke check 1 in the positive direction on each axis
1321 Coordinate value I of stored stroke check 1 in the negative direction on each axis
[Data type] 2–word axis
[Unit of data]
Increment system IS–A IS–B IS–C Unit
Millimeter machine 0.01 0.001 0.0001 mm
Inch machine 0.001 0.0001 0.00001 inch
Rotation axis 0.01 0.001 0.0001 deg
[Valid data range] –99999999 to 99999999
The coordinate values of stored stroke check 1 in the positive and negative
directions are setfor each axis in the machine coordinate system. The
outside area of the two checks set in the parameters is inhibited.
(Xp,Yp,Zp)
Set the machine coordinates of the
boundaries in the positive direction
(Xp, Yp, and Zp) using parameter No.
1320, and those of the boundaries in
the negative direction (Xm, Ym, and
Zm) using parameter No. 1321. The
prohibited area thus becomes the
hatched area in the figure on the left.
(Xm,Ym,Zm)
NOTE
1 For axes with diameter specification, a diameter value must
be set.
2 When the parameters are set as follows, the stroke becomes
infinite:
parameter 1320 < parameter 1321
For movement along the axis for which infinite stroke is set,
only increment commands are available. (The stored stroke
limit switching signal also becomes invalid.) If an absolute
command is issued for this axis, the absolute register may
overflow, and normal movement will not result.
3 The prohibited area specified with these parameters is
invalid if bit 2 (LMS) of parameter No. 1300 is set to 1 and
stored stroke limit switching signal EXLM is set to 1. In such
a case, the settings of parameters No. 1326 and 1327 are
used, instead.
