Stored Stroke Limit - Mitsubishi Electric MELDAS C6 Instruction Manual

6. Stored Stroke Limit

(1) Outline
Three tool entry prohibited ranges can be set with stored stroke limit I, stored stroke limit II or 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.
As for the stored stroke limit II and IIB, the prohibited range is selected by the parameter.
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.
This function is an option.
[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.
(Note) If the absolute position detection is valid when using the absolute position detection
[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.
(Note) The axis movement possible when the reference point return has not yet completed is
