9 Setting the Tool Entry Prohibited Range

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.
Prohibited
Type
range
- Set by the machine tool builder.
- When used with II, the confined range designated
Ⅰ Outside
by the two functions becomes the movement valid
range.
Ⅱ Outside
- Set by the user.
- Select II or IIB with the
parameters.
IIB Inside
IB Inside - Set by the machine tool builder.
