The iQpump drive can be configured to program the drive using units or scaling that are appropriate for the pumping system by
programming the System Units (P1-02). The System Units will affect setpoint references, feedback scaling, pump levels, and display
monitors. The following is a list of parameters that are affected by the programming of the System Units (P1-02).
• d1 Group: d1-01 through d1-04.
• o1 Group: o1-07, o1-08.
• P1 Group: P1-03, P1-04, P1-07, P1-09, P1-11, P1-13.
• P2 Group: P2-02, P2-04, P2-09, P2-10, P2-15, P2-16.
• P3 Group: P3-03, P3-05, P3-07, P3-08, P3-12, P3-14.
• P4 Group: P4-01
• U1 Monitor: U1-91
For further description of each parameter, please refer to the appropriate section or Appendix A.
P1-03 Feedback Device Scaling
■
Setting Range: 1 ~ 36000 [based on System Units (P1-02)]
Factory Default: 00145 PSI
The iQpump drive can be configured to scale the feedback signal using the Feedback Device Scaling Parameter (P1-03). The
programmed value in P1-03 represents the maximum level when a feedback reference is provided to the drive. An example: If a 4-20 mA
signal is provided and P1-03 is set to 145 PSI, then 20 mA would represent the maximum PSI readout level of 145 PSI. This parameter
works in conjunction with the System Units (P1-02).
Digits 1 through 4 set the desired number to be displayed at maximum feedback level. Digit 5 determines the number of decimal places in
the displayed number.
If Digit 5 = 0 number format is XXXX
If Digit 5 = 1 number format is XXX.X
If Digit 5 = 2 number format is XX.XX
If Digit 5 = 3 number format is X.XXX
Example 1: 00145 (factory default)
P1-02 = 1 (factory default)
P1-03 = 145 PSI (No decimal point)
Example 2: 11000 (one decimal point)
P1-02 = 1
P1-03 = 100.0 PSI (one decimal point)
