The value of this parameter represents the time it would take to adjust the setpoint if it were changed from 0 to 100%. This
feature can be used to smooth 'nervous' controller behavior, e.g. to reduce setpoint overshoot or undershoot.
The supported range corresponds to 0…3000 seconds. Default value = 0.
Example:
If
Setpoint Slope
= 100 it will take 10 seconds to adjust the setpoint if it is changed from 0 to 100%. A setpoint change of 20%
will take (20%/100%)*10 seconds = 2 seconds.
