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.
