8.1.5 AP2-40 Start & End Ramp Operation
This function is used to rapidly accelerate the pump to the normal operating level, or to rapidly
decelerate the pump and stop it. Start & End ramp operation is performed when ADV-24 (Freq
Limit) is set to ‘1 (Yes).’

AP2-41
Start Ramp Acc
Refers to the time it takes to reach the minimum pump operation frequency
for a Start & End Ramp operation (Freq Limit Lo) set at ADV- 25 when the
inverter starts (it is different from DRV-03 acceleration slope).
AP2-42
End Ramp Dec
Refers to the time it takes to reach the 0 step (stop) from the minimum pump
operation frequency for a Start & End Ramp operation (Freq Limit Lo) set at
ADV-25 (it is different from DRV-03 deceleration slope).
In the figure above, AP2-41 defines the acceleration time to the minimum operation frequency
ADV-25 (Freq Limt Lo). AP2-42 defines the deceleration time from the minimum operation
frequency to a stopped state. Time A (normal acceleration time set at DRV-03) and Time B (normal
deceleration time set at DRV-04) in the figure will change according to the Acc/Dec slopes defined
by AP2-41 and AP2-42.
