Ramp rise rate setup programs take the PV at start of program opera-

When the rate of rise is changed midway during operation, the SP rate of
rise and the step time in the ramp cycle both change.

• In the above figure, increasing the rate of rise results in a shorter target
step time. Likewise, when the SP is changed, the step time of the ramp
cycle also changes.
• When the soak time is changed, only the step time in the soak cycle
changes.
