Software Setup and Operation
Figure 68: Input Functions Screen
To assign an input function, use the up/down arrows to move the cursor to the desired input
function, type in the desired line number and then press <Enter>. The left hand window will
then show the function beside the selected input line. If you wish to access a function that is
off the screen, press the up/down arrow key or page down until the cursor is on the desired
function. The screen will scroll as needed.
When an input line is activated, the corresponding input line on the PCX screen will be
highlighted. This may be useful when setting up or testing the drive inputs.
Input Polarity
To define an input function as normally off (-) or normally on (+), move the cursor to the
chosen function, press the (+) or (-) key and <Enter>. A normally off function will be inactive
until a signal is applied to its input line. A normally on function will be active until the signal
is removed from its input line.
When assigning + or - travel limits, the recommended practice is normally on. This requires
correct voltage, power and wiring to keep the alarm off.
The input polarity feature does not apply to the following input functions:
0 - Index Initiate 25 - Return to Position
1 - Home (0) Initiate 29 - Program Initiate
4 - Jog -31 - Suspend Program
