4.6 Basic iQpump Setup and Application Preset Parameters
n
Q5-10: Low Suction Pressure Detection Time
Sets the delay time after which a Low Suction Pressure alarm or fault will occur. When the suction pressure feedback falls
below the Q5-09 setting for the time set in Q5-10, the drive will respond based on the setting in Q5-11.
No.
Q5-10
n
Q5-11: Low Suction Pressure Behavior Select
Selects the drive response to a Low Suction Pressure condition. When the suction pressure feedback falls below the Q5-09
setting for the time set in Q5-10, the drive will respond based on the setting in Q5-11. By setting Q5-11 to 3 (Restart Q5-15),
the drive will attempt to reset itself for the number of times set in L5-01 waiting for the Q5-15 reset time before each reset
attempt. The drive will fault if the L5-01 attempts are exceeded.
No.
Q5-11
Setting 0: No display (digital output only)
Setting 1: Alarm only
Setting 2: Fault
Setting 3: Auto-restart (time set in Q5-15)
n
Q5-16: Suction Control Proportional Gain
Sets the proportional gain of the Suction Pressure controller. Increasing this value will make the system more responsive but
can lead to instability. Q5-16 is used in place of b5-02 for suction pressure control.
No.
n
Q5-17: Suction Control Integral Time
Sets the integral time of the Suction Pressure controller. Decreasing this value will make the system more responsive but can
lead to overshoot. Q5-17 is used in place of b5-03 for suction pressure control.
No.
