Q5-03: Suction Pressure Setpoint
Sets the Suction Pressure setpoint. The units of Q5-03 are selected in Q5-01 and the scaling is set in Q5-02 (Suction Transducer
Scaling). The Suction Pressure function is enabled by setting Q5-01 = 1 (Suction Pressure). This function uses Q5-03 as the
setpoint instead of Q1-01, and Q5-02 as the feedback scaling instead of P1-02. Set b5-01 to a value other than 0 to enable the
drive PID controller and use this function.
This feature can be used to allow the drive to control (outlet) pressure when there is adequate pressure on the inlet side of the
pump by setting Q5-01 to 1 (Suction Pressure). When the suction pressure (pump inlet pressure) drops to the Suction Pressure
Setpoint (Q5-03), it will regulate the suction pressure and the outlet pressure will be allowed to drop. This requires both a
suction pressure transducer on the pump inlet and a pressure feedback transducer on the pump output.

Q5-06: Wake-Up Suction Pressure
Sets the wake up level for the suction pressure control function. The drive falls asleep based on the Q5-04 level and Q5-05
delay time. The drive will wake up when the suction pressure feedback rises above the Q5-06 setting for the time set in Q5-07
AND the standard sleep function calls for a wake up (P1-04 and P1-05).
No. Parameter Name Setting Range Default
Q5-06 Wake-Up Suction Pressure 0.0 to 1200.0 30.0 PSI
n
Q5-09: Low Suction Pressure Detection Level
Sets the level at which a Low Suction Pressure alarm or fault will occur.
