23 Setting the Tool Entry Prohibited Range
23.2 Stored Stroke Limit
[Valid Conditions of Stored Stroke Limit]
When using the relative position detection system, the stored stroke limit is invalid until the reference position return is
completed after the power is turned ON.
The stored stroke limit can be enabled without completing a reference position return by setting "#2049 type (Absolute
position detection method)" to "9".
Note
(1) If the absolute position detection is valid when using the absolute position detection system, the stored stroke limit will be
validated immediately after the power is turned ON.
[Stored Stroke Limit Coordinates]
The stored stroke limit check is carried out in the basic machine coordinate system established by the reference position
return.
When the stored stroke limit has been validated while the reference position return has not been completed, the stored stroke
limit check is executed with the basic machine coordinate system at the time of last power-OFF as temporary one.
When the 1st dog-type reference position return is completed after the power is turned ON, the proper coordinate system is
established.
Note
(1) While the reference position return has not been completed, only the manual and handle feed mode allow the axis move-
ment. Automatic operation is validated after the reference position return is completed.
CAUTION
Always set the stored stroke limit. Failure to set this could result in collision with the machine end.
The stored stroke limits I, II, IIB, IB and IC are handled as follows.
Prohibited
Type
range
- Set by the machine tool builder.
I Outside - When used with II, the confined range designated by
the two functions becomes the movable range.
II Outside
- Set by the user.
- Select II or IIB with the
parameters.
IIB Inside
IB Inside - Set by the machine tool builder.
IC Outside - Set by the machine tool builder.
 The stroke check will not be executed when both maximum and minimum value are set to the same value.
 This function is valid after the reference position return if the system does not apply the absolute position detection system.
 Before the machine enters the prohibited range, an error "M01 Operation error 0007" (S/W stroke end) will occur, and the
machine will stop moving. The alarm can be reset by moving the erroneous axis in the opposite direction.
 During automatic operation, if an alarm occurs with even 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.
