B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 53 -
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 set for 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 <G007#6> is set to 1. In
such a case, the settings of parameters No. 1326
and 1327 are used, instead.
