|
Enable. The controller is enabled
when input 1 is applied. This input is optional; if the input is not
connected, the controller is automatically enabled. |

Setpoint. |
PR
|
Percent
|
Output of the manipulated variable as
0-100% value.
|
PW
|
PWM
|
Output of the manipulated variable as
PWM signal, here the time from the Time base parameter is used for
the clock.
|
Regulation
period
|
Control time in seconds. The outputs
are updated at this interval.
|
P:
Gain
|
P Part of the PID controller.
|
I:
Integral time
|
Integral time, I component of the PID
controller. The difference is added up in this time, a lower time
therefore means a higher I component.
|
D:
Differential
|
D Part of the PID controller.
|
Setpoint
Min.
|
Limitation setpoint variable Minimum

Setpoint
Max.
|
Limitation setpoint variable Maximum |
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.
