2. PREPARATIONS FOR OPERATION
106
CAUTION
In the cases below, the automatic release function is
disabled. To release an alarm, a reset operation is required.
1 When a setting is made to issue an alarm before a stored
stroke limit is exceeded (bit 7 (BFA) of parameter No.
1300)
2 When an another overtravel alarm (such as stored stroke
check 2, stored stroke check 3, and interference check) is
already issued
OTF Specifies whether to change the specification of the stored stroke check,
as follows:
0 : Not to change.
1 : To change as stated below.
S If the BFA (bit 7 of No. 1300) parameter is 1, stored stroke check
1 for a manual operation causes the axis to stop on the border and
an alarm to be issued.
S If the BFA (bit 7 of No. 1300) parameter is 1, stored stroke check
2 causes an alarm to be issued just before the stroke check is passed
through.
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 each axis
[Data type] Two–word axis
Increment system IS–A IS–B IS–C Unit
Metric input 0.01 0.001 0.0001 mm
Inch input 0.001 0.0001 0.00001 inch
Rotation axis 0.01 0.001 0.0001 deg
[Valid data range] – 99999999 to 99999999
Define the coordinate values of stored stroke checks 1 in the positive and
negative directions for each axis in the machine coordinate system. For
each axis, travel beyond the defined limits is prohibited.
WARNING
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 incremental commands are available. If an absolute
command is issued for this axis, the absolute register may
overflow, and normal movement will not result.
