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.

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.

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.

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.
