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.
