P1-03: Feedback Device Scaling

Sets the feedback device scaling used for the PID controller. This information can be found on the nameplate or specification

sheet and is usually expressed as the maximum output of the device.

For example, a pressure sensor scaling might be 145.0 PSI at 20 mA output and would require setting P1-03 to 145.0 PSI.

Note: Set this parameter prior to changing other parameters related to the PID feedback, as internal scaling is based on P1-03.

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
