5. Stored Stroke Limit
III-28
5. Stored Stroke Limit
(1) Outline
Three tool entry prohibited ranges can be set with stored stroke limit I, stored stroke limit II, IIB and stored
stroke limit IB. Part of the prohibited range on the outside of soft limit I can be validated with stored stroke
limit IC.
The stored stroke limit II and IIB select the outer side (II) and inner side (IIB) of the entry prohibited range
with parameters.

If the tool tries to move 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.
[Valid Conditions of Stored Stroke Limit]
When using the relative position detection system, the stored stroke limit is invalid until the reference
point return is completed after the power is turned ON.
The stored stroke limit can be validated even if the reference point return is not yet completed, by setting
parameter #2049 type = 9.
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 point return. To validate the stored stroke limit even when the reference point return is not yet
completed, check the stored stroke limit using the temporary basic machine coordinate system (basic
coordinate system defined when the power was previously turned OFF).
When the 1st dog-type reference point return is completed after the power is turned OFF, the correct
coordinate system is established.
CAUTION
Always set the stored stroke limit. Failure to set this could result in collision with the machine end.
(Note) The axis movement possible when the reference point return has not yet completed is limited to
manual and handle feed only. Automatic operation is validated after the reference point return is
completed.
