7.3 Ramp and Soak Function 

This  function  is  used  to  stop  the  sudden  change  of  set  point.  The  ramp  function  is 
performed  in  following  conditions.  The  target  set  point  is  changed.  Target  set  point 
number is changed. (For example: Switching from SP-1 to SP-2). The power is turned 
ON  or  the  controller  is  recovered  from  power  failure.  A  change  is  made  from  manual 
mode to auto mode. 
When the proc

ess value crosses the set point value for the first instant, a “soak period” 

begins.

 

 

 

The  ramp  function  will  be  performed  when  ramp  unit  parameter  is  selected  as 

MInR

(minute rate) or 

HRR

 (hour rate). The ramp rate can be programmed by setting the 

parameter 

rmp.r

The Soak rate is programmed by setting 

sok.r.

 Soak time will be performed according 

to 

s.hod

 and 

s.rst.

 When the soak type is 

s.hod

 it will not reset the soak rate when the 

power  is  down  and  when  the  Soak  type  is 

s.rst

  it  will  reset  the  soak  rate  when  the 

power is down. 
 
The ramp and Soak function will be cancelled in following conditions. 

 

A change is made from Auto mode to manual mode. 

 

Sensor Failure occurs. 

 

Auto tuning function is activated.
