9.2 Storeed Stroke Limit (S/W OT)

9.2.1 Outline

Three tool entry prohibited ranges can be set with stored stroke limit I, stored stroke limit II, IIB and stored stroke limit IB.
Set the parameters to select the entry prohibited range for stored stroke limit II or IIB.
( Ⅱ : Prohibits entering outside the range IIB: Prohibits entering inside the range)
(A): Prohibited range by stored stroke limit I
(B): Prohibited range by stored stroke limit IIB
(C): Prohibited range by stored stroke limit IB
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.
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 validated by setting "#2049 type (Absolute position detection method)" to "9"even if
the reference position return is not yet completed.
(Note) 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 making the stored stroke limit validated while the reference position return has not been completed, execute
the stored stroke limit check 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) While the reference position return has not been completed, only the manual and handle feed mode allow
the axis movement. Automatic operation is validated after the reference position return is completed.
Always set the stored stroke limit. Failure to set this could result in collision with the machine
