Soft-Start
The controller has soft start function to limit the control output of OUT1 and OUT2 for a
programmable time (SFT) or up to a programmed threshold value (SFTH). Once the time/temperature
threshold has been reached, the soft start function will terminate and normal PID control begins. This function
is useful to avoid full power to the load during start-up.
Note:
In Profile Version controllers, if “PFR” is set to something other than “SP1”, the profile function will
continue with the set parameter during power recovery. If “PFR” is set to SP1, then the profile will continue to
run with soft start parameters during power recovery.
There are 5 parameters available for the soft start function. They are as below.
1.
SFt:
Soft start time. If the SFt
≠
0, the Soft start function will be enabled. The SFt can be set in the
form of Hour:Minute. The range can be set from 00.00 to 99:59.
2.
SFL1:
Soft Start output limit for output 1. It can be set from PL1L to PL1H.
3.
SFL2:
Soft Start output limit for output 2. It can be set from PL2L to PL2H.
4.
SFtH:
Soft start threshold value. The Soft start will be aborted when the process value is greater than
or equal to SFtH.
5.
SFtR:
Soft start time. It will show the remaining time of soft start while it is running.
