Operation when a value outside the override factor setting range is set
If a value outside the setting range is set in each override factor, the warning "Out of Speed Override Coefficient Range
Warning" (warning code: 0D0BH) and the warning "Out of Acceleration Override Coefficient Range Warning" (warning code:
0D0CH) will occur, and the override factor will remain unchanged from the previous value.

Warning
Operation at velocity/acceleration/deceleration limit value over by override
■When velocity limit value over occurs by velocity override.
Velocity over will occur during control execution and the velocity will not change.
When acceleration override factor is changed, the acceleration and deceleration will change. In this case, when acceleration
limit value over occurs, the acceleration over will occur and the acceleration will change. When deceleration limit value over
occurs, the deceleration over will occur and the deceleration will not change as well. (An error does not occur by a control data
change, and the override factor is changed.)

Speed limit value over
When the set velocity is increased to 200%,
velocity change is not executed because the value
exceeds the speed limit value. (Axis warning
Since the override factor value has
100%
been read, the following FB2 operation is
executed as 200% speed of the starting.
