146 YASKAWA TM.iQp.07 iQpump Controller Programming Manual
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.
(*su1) When P1-02 = 13, parameter P1-03 will have to be set to (120 x E1-04 / E2 / 04) for proper display. When P1-02 = 14, parameter
P1-03 will have to be set to the same value as E1-04 for proper display.

◆ 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).
