Decreasing Segment-time in Ramp Segment
The remaining segment time from the time when the hold state is released can be
changed during the hold operation.
However, the ramp-rate for the changed program setpoint changes.
When the remaining segment time is changed in the ramp segment and the hold state is
released, the program pattern operation restarts from the changed segment time.
When the segment time is increased, the segment time and the time of the time event
are extended by the increased amount of time.

Increasing Segment-time in Ramp Segment
The remaining segment time from the time when the hold state is released can be
changed during the hold operation.
However, the ramp-rate for the changed program setpoint changes.
When the remaining segment time is changed in the ramp segment and the hold state is
released, the program pattern operation restarts from the changed segment time.
When the segment time is decreased, the segment time and the time of the time event
are shortened by the decreased amount of time.
