AC/S 1.x.1 | 2CDC508198D0211 Rev. A 129
Room temperature control example:
The
setpoint
and
actual value
are two temperatures. The output value is the control value for a valve
actuator.

Integral time in [s]; typical value
range: 60...900 s
Integral time as
input
- Yes
- No
If
Controller
type
= PI or
PID
Derivative time
Floating point number in [s],
default = 1
If
Controller
type
= PD or
PID
Derivative time in [s]; typical
value range: 1...10 s
Derivative time
as input
- Yes
- No
If
Controller
type
= PD or
PID
Limit output
value, anti-wind-
up
- Yes
- No
Always
Limits the output value to a
range. If this range is exceeded,
a limit is imposed on the integral
element in the controller ("anti-
wind-up")
Lower limit
Floating point number,
default = 0
Always
Upper limit
Floating point number,
default = 255
Always
Description of parameters
Controller type:
Value
Description
P (Proportional)
Proportional controller. The integral and derivative coefficients are 0.
PI (Integral)
Proportional integral controller. The derivative coefficient is 0.
PD (Derivative)
Proportional derivative controller. The integral coefficient is 0.
PID
Proportional integral derivative controller
If the controller type is P (Proportional), the integral value and derivative value are always 0.
