The address established by OPR is used to set the upper and lower limits of the
moveable range of the workpiece in this function.
Movement commands issued to addresses outside that setting range will not be
executed.
The relation between the software stroke limit and the each control is shown below.
If the positioning data of position command exceeds the software limit is started, an
"error code 1501" will occur and the operation does not start.
And, an "error code 1501" will occur and the deceleration stop is made at point change in
operation.
If the positioning data of position command exceeds the software limit is set for the axes
in one group, an "error code 1501" will occur and the operation does not start.
And, an "error code 1501" will occur and the deceleration stop is made at point change in
operation.
If it starts in the opposite direction against of OPR from outside the software limit range,
an "error code 1501" will occur and the operation does not start.
If it is reached to the software stroke limit in operation, an "error code 1502" will occur
and the deceleration stop is made so as not to exceed the software stroke limit.
If the incremental feed amount that exceeds the software stroke limit is set, an "error
code 1501" will occur and the operation does not start.
The software stroke limit is not checked.
If the change address exceeds the software stroke limit at target position change
function execution, an "error code 1501" will occur and the deceleration stop is made.
If the change address exceeds the software stroke limit, an "error code 1501" will occur
and the current value change is not executed.
POINT
• If a continuous path is set in "
after changing the positioning data exceeds the software stroke limit, an "error
code 1501" will occur at positioning data change, and the deceleration stop is
made. At this time, if a distance to software stroke limit is shorter than a distance
that needed for deceleration, the servo may stop outside the software stroke limit.
• In an error set due to exceeding the software stroke limit, the servo is stopped by
" Deceleration time".
