7.30 PROCESS PID MULTI-STAGE SETTING (GROUP F7.1)
F7.1.27~F7.1.33 Process PID
multi-stage preset
Setting range: -100.0~100.0%
Factory default: 0.0
This group of parameter defines the set value of process
PID
multi-stage operation. Set value is the relevant
percentage of process PID set value determined in
F7.0.01.
Multi-stage operation of process
PID
can be flexibly realized with multifunction input terminal, please refer to
function instruction of given terminal 1, 2, 3(28~30)
