Programmable inputs and outputs are provided to allow the controller to detect and respond to
the state of switches, thumbwheels, electronic sensors, and outputs of other equipment such as
drives and PLCs. Listed below are the programmable functions that may be assigned to the
programmable I/O.
Programmable I/O offering differs by product. The total number of onboard inputs and
outputs (trigger inputs, limit inputs, digital outputs) depends on the product. The total number
of expansion inputs and outputs (analog inputs, digital inputs and digital outputs) depends on
your configuration of expansion I/O bricks. To ascertain your product's I/O bit patterns, refer
to page 91.
Refer to page 90 for instructions on establishing programmable input and output functions.
Instructions for connecting to I/O devices are provided in your product's Installation Guide.
Input functions may be assigned to two basic groups of programmable inputs.

expansion I/O bricks. The syntax,

Letter Designator Function
A....................General-purpose input (default function for triggers & inputs on I/O bricks)
B....................BCD program select
C....................Kill
D....................Stop
E....................Pause/Continue
F....................User fault
G....................<RESERVED>
H....................Trigger Interrupt for position capture or registration (trigger inputs only). Special trigger
functions can be assigned with the TRGFN command (see page 166).
I....................Cause alarm event (requires Ethernet interface) in Communications Server
J....................Jog in the positive-counting direction
K....................Jog in the negative-counting direction
L....................Jog velocity select
M....................Joystick release
N....................Joystick axis select
O....................Joystick velocity select
P....................One-to-one program select
Q....................Program security
R....................End-of-travel limit for positive-counting direction *
S....................End-of-travel limit for negative-counting direction *
T....................Home limit *
* The limit inputs are factory-set to their respective end-of-travel or home limit function (see page 91).
Command Function
OUTFNCi-A ............General-purpose output (default function)
OUTFNCi-B ............Moving/not moving
OUTFNCi-C ............Program in progress
OUTFNCi-D ............Hardware or software end-of-travel limit encountered
OUTFNCi-E ............Stall indicator — stepper axes only
OUTFNCi-F ............Fault indicator (indicates drive fault input or user fault input is active)
OUTFNCi-G ............Position error exceeds max. limit set with SMPER — servo axes only
OUTFNCi-H ............Output on position
* The "i" in the command syntax represents the number of the programmable input (e.g., OUTFNC3-H
assigns onboard output #3 as an "output on position" function).
