9 Setting the Tool Entry Prohibited Range
MITSUBISHI CNC
146
9.2.2 Detailed Explanation
The stored stroke limit sets a prohibited range with the parameters or program command. The minimum and maximum
values of the prohibited range are set as the coordinate value (radius value) on the machine coordinate system for each
axis.
-
The stroke check will not be executed when a same value is set to both maximum and minimum value.
-
This function is valid after the reference position return if the absolute position detection system is not applied.
-
Before the machine enters the prohibited range, an error "M01 Operation error 0007" (S/W stroke end) will occur,
and the machine movement will stop. The alarm can be reset by moving the erroneous axis in the opposite
direction.
-
During automatic operation, if an alarm occurs with even with one axis, all axes will decelerate to a stop.
-
During manual operation, only the axis that caused the alarm will decelerate to a stop.
-
The axis will always stop at a position before the prohibited range.
-
The distance between the prohibited range and stop position will depend on the feedrate, etc.
The stored stroke limits I, II, IIB and IB are handled as follows.

parameters
Validating conditions
Ⅰ
Outside
- Set by the machine tool builder.
- When used with II, the confined range designated
by the two functions becomes the movement valid
range.
"#2013 OT -
(Soft limit I -)"
"#2014 OT +
(Soft limit I +)"
- Reference position return is
completed.
- #2013 and #2014 are not set to
the same value.
Ⅱ
Outside
- Set by the user.
- Select II or IIB with the
parameters.
- "#8210 OT-INSIDE" = "0"
- Used with I.
"#8204 OT-CHECK-N"
"#8205 OT-CHECK-P"
- Reference position return is
completed.
- #8204 and #8205 are not set to
the same value.
- "#8202 OT-CHECK OFF" = "0"
IIB
Inside
- "#8210 OT-INSIDE" = "1"
IB
Inside
- Set by the machine tool builder.
"#2061 OT_1B-
(Soft limit IB -)"
"#2062 OT_1B+
(Soft limit IB +)"
- Reference position return is
completed.
- #2061 and #2062 are not set to
the same value.
