4.3 Set-point processing

The set-point processing structure is shown in the following picture:

4.3.1

Set-point gradient / ramp

To prevent set-point step changes, parameter

r set-point r

r.SP can be adjusted to

a maximum rate of change. This gradient is effective in positive and negative direction..

With parameter

r.SP set to OFF (default), the gradient is switched off and set-point

changes are realized directly.
(for parameter: see page 55)

4.3.2

Cooling functions

The configuration parameter

CYCL (ConF/ Cntr/ CYCL) can be used for matching

the cycle time of 2-point and 3-point controllers. This can be done using the following 4
methods.

4.3.3

Standard (

CyCl= 0 )

The adjusted cycle times

t1 and t2 are valid for 50% or -50% correcting variable. With

very small or very high values, the effective cycle time is extended to prevent unreasonably
