P6-07
(0D64)
Low Flow Detection
Delay Time When
Already Running
Low Flow Tim Run
Sets the length of time that the flow rate must be below the level
set in P6-06 to detect a Low Flow condition.
Default: 10 s
Min.: 0
Max.: 6000
–
P6-08
(0D65) Low Flow Detection
Wait Time at Start
Low Flow Time St
Sets the length of time that the drive will wait after coming out
of a zero speed condition before activating Low Flow detection.
Note:
This feature is canceled when the Flow Rate rises
above the Low Flow Level for the time set in
P6-21, Low Flow Start Delay Cancel Time.
Default: 0.0 min
Min.: 0.0
Max.: 3600.0

Low Flow Auto-Restart
Time
LowFlow Restart
Set the length of time that the drive will wait before attempting
an auto-restart of the Low Flow fault.
This parameter is effective only when P6-09 is set to 3.
Default: 3.0 min
Min.: 0.1
Max.: 6000.0

P6-11
(0D68) Accumulation Level -
Millions
AccumLvl*1000000
Sets the accumulated volume that will trigger the Accum Level
alarm, Accum Level fault, or the Accum Level digital output.
Accum Level is calculated using the following formula:
Level = (P6-11 * 1000000) + (P6-12 * 1000) + P6-13 + P6-14)
Min.: 0
Max.: 65535

(0D6C) Accumulation Behavior
Accum Behavior
0: No Display
1: Alarm Only
2: Fault
3: Fault-ResetAccum
4: Stop & Alarm
5: Stp/Alm/RstAccum
Determines drive response when the accumulated volume
reaches the P6-11 to P6-14 level.
0: No display
1: Alarm only
2: Fault
3: Fault - Auto flow accum reset
4: Stop and alarm
5: Stop, alarm, and reset flow accumulation

Flow Meter
Accumulator Units
Select
Accum Units
1: Gallons (gal)
2: Acre-Feet (A-F)
Selects whether the drive accumulates flow in gallons or acre-
feet.
1: Gallons (gal)
2: Acre-feet
Note:
Changing this parameter resets the accumulated
flow (U1-84 to U1-87) to zero.
Default: 1
Range: 1, 2

P6-17
(0D6E) High Flow Level
High Flow Level
Sets the level above which the flow must rise for the time set in
P6-18 to trigger a High Flow condition.
Default: 0.0
GPM
Min.: 0.0
Max.: 6000.0
P6-18
(0D6F) High Flow Detection
Delay Time
High Flow Time
Sets the length of time that the flow rate must be above the level
set in P6-17 to detect a High Flow condition.
Default: 10 s
Min.: 0
Max.: 6000

Accumulator Stopping
Method Selection
Accum Stop Sel
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
Selects how the drive stops when the Flow Accumulator has
reached its target level (P6-11 to P6-14). Effective only when
P6-15 (Accum Behavior) is set for Fault or Stop (selections 2 to
5).
Default: 1
Range: 0 to 2
