Setpoint ramp up/ -down
On initial start-up, after the fan enable signal becomes true (=1), the setpoint of the SPB_AirFLowControl will be ramped up, from zero to the value of the desired setpoint, as it is defined by the output "CalcAirFlow". When during normal operation the setpoint of the duct air flow is lowered, a ramp-down function will be effective. Both ramping-up and ramping-down are defined by parameter DSP-01, as shown in the next figure.
