Epsilon EP-P Drive and FM-3/4 Module Reference Manual

The analog output is scaled from the units of the selected variable to the +10/-10 volt range of the Analog Output. It is a linear

scale with offset defined by entering two points on the scale, a minimum and maximum to correlate the user units to analog

voltage. The actual minimum and maximum range of either user unit or analog voltage does not need to be entered as the

algorithm will extrapolate the ranges.

Figure 75: Analog Outputs View

Enable Channel Check Box

By default, the analog output channels are not enabled meaning that a value is not being sent to the analog circuit. When the

channel is disabled (check box is clear), the configuration parameters for that analog output are unavailable and therefore

have no effect. To enable the output, simply select the Enable Channel check box, and the configuration parameters will

become available to edit.

If the user wishes to control the Analog Output through other means, it is necessary to clear the Enable Channel check box.

Source

This list box allows the user to create a direct connection from a Source parameter to the Analog Output. The current value

of the parameter selected as the Source will directly determine the value of the Analog Output signal. The Source list box

contains a list of predefined parameters to select from.

FM Only

FM Var

The Module Variable parameter is only available once the user has selected Module Variable from the Source list box

above. This text box is used to define what parameter will control the Analog Output. The selected module parameter will

directly determine the value of the analog output based on the Max and Min scaling values entered on this view. The

parameter is entered here in program format or see Popup Variables Button, below.

FM Only

Popup Variables Button

Click this button to open the Select FM Variables window. Select the variable and then drag the variable over to the FM

Var text box to assign the variable to the Analog output channel.

Maximum Value

The analog output is a linear interpolation of the selected module variable between the minimum and maximum specified end

points. Each end point is specified as the user value and the corresponding output value at that point. The number of decimal

places for both values is taken from the selected module variable. MaxUserValue is the maximum user unit value which

corresponds to the maximum analog output value.
