12.5 ELECTRONIC POTENTIOMETER [37]
The ELECTRONIC POTENTIOMETER (E.P.) function allows that the speed reference be adjusted by means of 2
digital inputs (one for incrementing it and another for decrementing it).
In order to enable this function, the speed reference must first be configured to be via E.P., by setting P0221 = 7
and/or P0222 = 7. After this function has been enabled, it is only necessary to program two of the digital inputs
(P0263 to P0270) in 11 (Increase E.P.) and 12 (Decrease E.P.).
The operation of this function can be observed in the next figure. It is important to point out that the increase
of the speed reference is done with the application of 24 V at the digital inputs, whereas the decrease is done
with the application of 0 V.
In order to reset the reference, 24 V must be applied at the "INCREASE" input and 0 V at the "DECREASE" input,
simultaneously while the CFW-11 inverter is disabled.
