Manipulated variable
|
Manipulated variable. |
PR
|
Percent
|
Output of the manipulated variable as a 0-100%
value.
|
PW
|
PWM
|
Output of the manipulated variable as a PWM
signal; for this, the time from the parameter time base is used for the
cycle.
|
|
Control time
|
Control time in seconds. The outputs
are now updated at this interval.
|
|
P:
Gain
|
P component of the PID controller.
|
|
I:
Reset time
|
Reset time, I component of the PID
controller. The difference is accumulated over this time, so a
lower time means a higher I component.
|
|
D:
Derivative
|
D component of the PID controller.
|
|
Manipulated variable
Min.
|
Manipulated variable minimum limit
|
|
Manipulated variable
Max.
|
Manipulated variable maximum limit |
|
PWM
time base
|
PWM time base. Example: With a
manipulated variable of 40% and a time of 10 seconds, the PWM
output is switched on for 4 seconds and off for 6 seconds.
