Yaskawa iQpump1000 AC Drive Quick Start - Manual (Page 225)

No. Parameter Name Setting Range Default
P1-03 Feedback Device Scaling 0.1 to 6000.0 145.0 PSI
n P1-04: Start / Draw Down Level
Sets the wake up level from the Sleep function. This setting is dependent on whether PID is normal or inverse acting (b5-09).
When the drive is asleep and the PID feedback signal rises above (normal acting) or falls below (inverse acting) this setting
for the time set in P1-05, Start Level Delay Time, the drive will wake up.
No. Parameter Name Setting Range Default
P1-04 Start / Draw Down Level -999.9 to 999.9 0.0 PSI
n P1-05: Start Level Delay Time
Sets the delay time for waking the drive to prevent accidental wake up caused by erratic feedback.
No. Parameter Name Setting Range Default
P1-05 Start Level Delay Time 0 to 3600 s 1 s
n P1-06: Minimum Pump Speed
Sets the minimum speed at which the drive will run the pump. Most pumps cannot run at low speeds due to cavitation, so be
sure to consult the pump specification sheet for the minimum safe run speed.
No. Parameter Name Setting Range Default
P1-06 Minimum Pump Speed 0.0 to E1-04 40.0 Hz
n P1-08: Low Feedback Level
Sets the level at which a Low Feedback alarm or fault will occur. When the PID feedback falls below the P1-08 setting for
the time set in P1-09, the drive will respond based on the setting in P1-10.
No. Parameter Name Setting Range Default
P1-08 Low Feedback Level 0.0 to 6000.0 0.0 PSI
n P1-09: Low Feedback Level Fault Delay Time
Sets the delay time after which a Low Feedback alarm or fault will occur. When the PID feedback falls below the P1-08 setting
for the time set in P1-09, the drive will respond based on the setting in P1-10.
No. Parameter Name Setting Range Default
P1-09 Low Feedback Level Fault Delay Time 0 to 3600 s 10 s
n P1-10: Low Feedback Selection
Selects the drive response to a Low Feedback condition. When the PID feedback falls below the P1-08 setting for the time set
in P1-09, the drive will respond based on the setting in P1-10.
No. Parameter Name Setting Range Default
P1-10 Low Feedback Selection 0 to 2 0
Low feedback detection is enabled when:
• P1-08 > 0.0
• Drive is running in AUTO Mode, including sleep boost and feedback drop detection (standard PID, b5-09 = 0)
• Run Command is present (including sleep and timer operation) (inverse PID, b5-09 = 1)
Setting 0: Fault
When feedback drops below the P1-08 level for longer than the time set in P1-09, the drive will fault on the “LFB – Low
Feedback” fault and coast to a stop.
The digital output programmed to “Low Feedback” (H2-0o = 97) closes. The drive will also display the “Low Feedback –
Low FB Sensed” alarm. The digital output will remain closed until the fault is reset.
