Analog Output Configuration

Parameters 75 and 85 [Anlg Out

n Select] are use to specify the signal used on

Analog Outputs 1 and 2, respectively. These parameters can be programmed to
the following selections.

Scaling

The scaling for the analog output is defined by entering analog output voltages
into two parameters, P91 [Anlg Out1 Lo] and P90 [Anlg Out1 Hi]. These two
output voltages correspond to the bottom and top of the possible range covered
by the quantity being output. Scaling of the analog outputs is accomplished with
low and high analog parameter settings that are associated with fixed ranges (see
the PowerFlex 750-Series Programming Manual, publication

750-PM001

,) for

each target function. Additionally, the PowerFlex 755 contains an adjustable scale
factor to override the fixed target range. P77 [Anlg Out0 Data] and 82 [Anlg
Out0 Val] are described in the following charts.
