9.1.2 SettingtheProgramPatternusingtheRamp-rateandSegmentTime
Description
The segment ramp time criterion bases segment operation on the target setpoint (TSP)
and the segment ramp-rate (TM.RT.)
Ramp time in segment ramp-up or ramp-down is expressed as an amount of change
(between target setpoints) per hour or per minute.
The unit of time is selected with parameter TMU. When segment is set for soaking at a
constant target setpoint, ramp time expresses the time duration of the segment.
Segmenttimeduringsoakoperations
When the target setpoint of the current segment is the same as that of the last segment,
soak operations are performed for the current segment.
The time duration of the soak segment is set with the ramp time parameter TM.RM.

Segmenttimeduringramp-upoperations
When the target setpoint of the current segment is higher than that of the last segment,
ramp-up operations are performed for the current segment.
During ramp-up, the amount of change (between target setpoints) per hour or per minute
is set with the ramp time parameter TM.RM.
