When setting the area by parameters, points A and B in the figure below
must be set.
B (I,J)
A (X,Y)
X>I, Y>J
X–I> 2000 (In least command increment)
Y–J> 2000 (In least command increment)
Fig. 6.3 (c) Creating or changing the forbidden area using a parameters
In limit 2, even if you mistake the order of the coordinate value of the two
points, a rectangular, with the two points being the apexes, will be set as
the area.
When you set the forbidden area through parameters (Nos. 1322, 1323),
the data should be specified by the distance from the reference position
in the least command increment. (Output increment)
If it is set by a G22 command, specify the data by the distance from the
reference position in the least input increment (Input increment.) The
programmed data are then converted into the numerical values in the least
command increment, and the values are set as the parameters.
Area can be set in piles.
Fig. 6.3 (d) Setting the forbidden area over lapping
Unnecessary limits should be set beyond the machine stroke.
Each limit becomes effective after the power is turned on and manual
reference position return or automatic reference position return by G28
has been performed.
After the power is turned on, if the reference position is in the forbidden
area of each limit, an alarm is generated immediately. (Only in G22 mode
for stored stroke check 2).
When the tool has become unmovable in the forbidden area, push the
emergency stop button to release the forbidden condition and move the
tool out of the forbidden area in the G23 mode; then, if the setting is
wrong, correct it and perform the reference position return again.
