Input Line Diagram
If the Input Line attached to the home sensor is debounced, the actual rising edge of the Home Sensor is used to determine
the Home Reference Position (the debounce time ensures a minimum pulse width).

Output Lines View

The Output Lines View displays any functions that have been assigned to the drive or module hardware outputs. See Figure

Descriptive text names can be assigned to individual output lines to make the setup easier to follow.

Analog Inputs View

The drive has one Analog input channel. The FM-4 module is able to use the analog input located on the drive. The analog
input accepts a +10 to -10 V signal. The drive has a 12-bit over sampled to 14-bit analog to digital converter (A/D), which is
used to transform the analog voltage to a usable parameter in the FM-4 module. The analog input is scanned by the drive
every 100 microseconds and the module at the trajectory update rate.
The analog input is scaled from +10 V to -10 V range to either the units of the selected variable or to the defined units. A
linear scale with offset is defined by entering two points on the scale, a min and max to correlate the user unit 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 range.
