Step 9 – Select Feedback Engineering Units (P1-01) and Scaling (P1-02)

Initially the display will read output frequency in (Hz) as the factory default and is set by parameter (Cn-28=0).If (Cn-28)is changed to (=1), then the display will read out in (%). The setting of (Cn-28)is only valid if (P1-01=0),which is the factory default. Other engineering units may be selected by parameter setting (P1-01)as described on the following page.

In this step, the feedback engineering units that the system is controlling such as CPM in fan applications or PSI in the case of pumps can be selected by parameter (P1-01). (See Appendix A for additional selections). The maximum value that the engineering units will be in any given application is set by parameter (P1-02). These selections will now be displayed on the digital operator.

Example: A pump application that has a feeedback transducer with a maximum value of 200 PSI i.e 200 PSI = 20mA or 10 Vdc, can be set as shown next.
