Sets the minimum speed at which the drive will run when the
drive is controlling suction pressure.
Suction Min Spd When the drive is controlling outlet pressure or this parameter
is set lower than P1-06 and P4-12, parameters P1-06 and P4-12
will be used as the minimum speed.
Sets the level below which the suction pressure must fall for the
time set in Q5-10 to trigger a drive response according to Q5-11,
Low Suction Pressure Behavior Select.
Setting this parameter to 0.0 will disable the function.
Low Pres Detect
Note:
Sets the length of time that the water level must fall below the
level set in Q5-09 to trigger drive response. Applicable when
Low Pres Det Tm
Q5-11 = 2 or 3. When Q5-01 = 2, Q5-10 detection time delay
applies to Q5-11 settings 1, 2, and 3.
Determines drive response when the suction pressure drops
below the level set in Q5-09 for longer than the time set in
Q5-10.

Note:
Sets the level above which the suction pressure must rise for the
time set in Q5-13 to trigger a drive response according to Q5-14.
Setting this parameter to 0.0 disables the function.
Hi Pres Detect
Note:
Sets the length of time that the water level must rise above the
Hi Pres Det Tm level set in Q5-12 to trigger drive response. Applicable when
Q5-14 = 2 or 3.
Determines drive response when the suction pressure rises
above the level set in Q5-12 for longer than the time set in Q5-13.

Note:
Sets the length of time that the drive will wait before attempting
an auto-restart of the Low Suction or High Suction fault.
Suction Restart
Parameter is only effective when Q5-11 is set to 3 or Q5-14 is
set to 3 and L5-01 is greater than 0.
Sets the proportional gain for the suction pressure control.
Suction P Gain
Sets the integral time for the suction pressure control.
Setting this parameter to 0.0 disables the suction pressure

Description
Q4-10 detection time delay is only applicable
when Q4-11 = 2 or 3. When Q5-01 = 2, Q5-10
detection time delay applies to settings 1, 2, and
3.
Q5-10 detection time delay only applies to
settings 2 and 3 while Q5-01 = 1. When Q5-01 =
2, Q5-10 detection time delay applies to settings
1, 2, and 3.
Q5-13 detection time delay only applies when
Q5-14 = 2 or 3.
Q5-13 detection time delay only applies to
settings 2 and 3.
