Note
When changing the final SP with the segment time ramp rate assignment method, the
segment time is also changed. The time event's event timer is not changed.
When increasing or decreasing the remaining segment time
You can increase or decrease the remaining segment time during the hold operation.
If the remaining segment time is increased or decreased during the hold operation, the ON/
OFF time and remaining segment time is automatically adjusted by the amount of time the
operation is held and the amount of time the segment time is increased or decreased.
