5. Stored Stroke Limit
III-29
(2) Detailed explanation
The stored stroke limit sets a prohibited range with the parameters or program command. The maximum
and minimum values of the prohibited range are set as coordinate values (radius values) on the basic
machine coordinate system for each axis. If the parameters (#8204 OT-CHECK-N and #8205
OT-CHECK-P), for setting the prohibited range, are set to the same value, the stroke will not be checked.
This function is valid only for the axis for which the reference point is established.
If the machine enters the prohibited range, an error "M01 Operation error 0007" (S/W stroke end) will occur,
and the machine movement will stop. 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.
The stored stroke limits I, II, IIB, IB and IC are handled as follows.
