Description
Retain.CtrlParams.Cool
.DWeighting
REAL 1.0 Active weighting of the derivative action for cooling
The derivative action may weaken with changes to the
setpoint.
Values from 0.0 to 1.0 are applicable.
• 1.0: Derivative action is fully effective upon setpoint
change
• 0.0: Derivative action is not effective upon setpoint
change
The derivative action is always fully effective when the
process value is changed.
Cool.DWeighting is retentive.
Only effective if the cooling output and PID parameter
switching are activated (Config.ActivateCooling = TRUE
and Config.AdvancedCooling = TRUE).
1.0 ≥ Cool.DWeighting ≥ 0.0
Retain.CtrlParams.Cool.Cycle REAL 1.0 Active sampling time of the PID algorithm for cooling in
seconds
CtrlParams.Cool.Cycle is calculated during tuning and
rounded off to an integer multiple of CycleTime..
If Config.Output.Cool.PwmPeriode = 0.0 and Config
.AdvancedCooling = TRUE, Cool.Cycle is used as period
duration of the pulse width modulation for cooling.
If Config.Output.Cool.PwmPeriode = 0.0 and Config
.AdvancedCooling = FALSE, Heat.Cycle is used as period
duration of the pulse width modulation for cooling.
Cool.Cycle is retentive.
Only effective if the cooling output and PID parameter
switching are activated (Config.ActivateCooling = TRUE
and Config.AdvancedCooling = TRUE).
100000.0 ≥ Cool.Cycle > 0.0
