7.1 Setting the Stored Stroke Limit

The tool entry prohibited ranges can be set with stored stroke limit II or IIB.
Set the parameters to select the entry prohibited range, stored stroke limit II or IIB.
(B)
(A)
(A): Entry prohibited range by stored stroke limit II (outside)
(B): Entry prohibited range by stored stroke limit IIB (inside)
If the axis is moving over the set range, an alarm will appear and the axis will decelerate to a stop.
If the prohibited range is entered and an alarm occurs, movement will be possible only in the direction opposite the entry
direction.
Enabling conditions of stored stroke limit
When using the relative position detection system, the stored stroke limit is invalid until the reference position return is com-
pleted after the power is turned ON.
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.
