Yaskawa iQpump Micro Quick Start - Manual (Page 77)

• Over-cycle Protection: Active when the drive is the only drive running on the network.
• Pre-charge: Active only on the first drive to run in the network.
• Low City Pressure: Active on any drive in the network. An alarm condition will cause other drives in the network to stop
running and show a “Net Pump Err” message.
• Utility Delay: When this function is active, the drive is unavailable to the iQpump MEMOBUS Network and will force the
Home Screen text to show “Pump Off Network”.
• Remote Drive Disable: When this function is active, the drive is unavailable to the iQpump MEMOBUS Network and will
force the Home Screen text to show “Pump Off Network”.
n P1-02: System Units
Selects the base unit in which most drive PID setpoints, scaling, monitors, limits, and faults/alarm levels will be set.
Note: Set this parameter prior to changing other parameters, as internal scaling is based on P1-02.
No. Parameter Name Setting Range Default
P1-02 System Units 0 to 10 1
Setting 0: No unit
Setting 1: PSI: Pounds per square inch
Setting 2: Pa: Pascals
Setting 3: Bar: Bar
Setting 4: "WC: Inch of water
Setting 5: "Hg: Inch of Mercury
Setting 6: ft: feet
Setting 7: m: meters
Setting 8: °F: Degrees Fahrenheit
Setting 9: °C: Degrees Celsius
Setting 10: Percent
n 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 Q1-01: PID Controller Setpoint 1
Sets the PID setpoint for the controller. The drive will use the system feedback signal and modulate the pump speed to regulate
the feedback at the Q1-01 setpoint. The units for Q1-01 are selected by b1-01 and the scaling is set in parameter P1-03. This
parameter is active when b1-01 (Reference Source) is set to 0 (HOA keypad).
No. Parameter Name Setting Range Default
Q1-01 PID Controller Setpoint 1 0.0 to 6000.0 0.0 PSI
