Start & End Ramp Operation Setting Details
Code Description
AP2-40 Start&End
Ramp
Sets the pump Start & End Ramp options.
Setting Function
0 No The Start & End Ramp operation is not used.
1 Yes Use the Start & End Ramp operation.
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 gradient).
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 gradient).
< Start&End Ramp Adjustment>
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 gradients
defined by AP2-41 and AP2-42.
