4.3 SP SLOPE function
▶ SP SLOPE function to make the Set Point ascend or descent gradually overtime.
▶ When changing the Target SP during FIX run operation, NSP (current SP) will be changed from current
PV to Target SP gradually by assigned ramping rate
▶ SP SLOPE Operation
▶ Operation mode
→ FIX mode
▶ Ramping rate
→ 20.0 ℃/min
Amount of change to TSP = [SP(TSP) - PV] and Slope = 20.0℃/min.
→ (70.0 - 30.0 )℃ = 40.0℃, it will take 2 min to ramp up to TSP.
☞ For 2 minutes, NSP will be changed from 30.0℃ to 70.0℃ at a constant
rate of 20℃/min.
