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

Note 1: When the program pattern-2 retransmission is selected (PT2.G=ON), the second loop is
also displayed for the parameter SSP. (LP2 lamp is lit.)
If it is set to 0.0% of the input range span, or the segment time 0.00, the program moves
to the next segment after one control period.
Use the parameter TMU to set the time unit. (Common in the instrument.)
When setting the program pattern via communication, set the time in minutes when the
time unit is set to hour.minute and set the time in seconds when the time unit is set to
minute.second.
When program pattern-2 retransmission is selected, priority is given to the conditions for
the program pattern for control.
When the control program pattern is set to ramp and the retransmission program pattern
is set to soak, the program pattern is set by the ramp. When the control program pattern
is set to soak and the retransmission program pattern is set to ramp, the program pattern
is set by the time.
