B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 51 -
BFA When a command that exceeds a stored stroke check is issued
0: An alarm is generated after the stroke check is exceeded.
1: An alarm is generated before the stroke check is exceeded.
NOTE
The tool stops at a point up to F/7500 mm short of
or ahead of the boundary.
(F: Feedrate when the tool reaches the boundary
(mm/min))

1301 PLC OTF OF1 OTA NPC DLM
[Data type] Bit
DLM The stored stroke limit switching signals <G104, G105> for each axial
direction is:
0: Disabled.
1: Enabled.
NPC As part of the stroke limit check performed before movement, the
movement specified in G31 (skip) and G37 (automatic tool length
measurement (for M series) or automatic tool compensation (for T
series)) blocks is:
0: Checked
1: Not checked
OTA If the tool is already in the prohibited area at power-up, an alarm of
stored stroke limit 2 (inside) or stored stroke limit 3 is:
0: Immediately raised.
1: Not raised before a movement is made.
Remark) When the alarm is immediately raised, the system enters the
state before power-down.
If this parameter is set to 1, no alarm is raised before a movement is
made. If the direction of this movement is a direction away from the
prohibited area, movements can be made in the opposite direction only.
Accordingly, there is danger that the tool enters the prohibited area
without an alarm.
OF1 If the tool is moved into the range allowed on the axis after an alarm is
raised by stored stroke check 1,
0: The alarm is not canceled before a reset is made.
1: The OT alarm is immediately canceled.
NOTE
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 and stored stroke check
3) is already issued
