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
