AT6200/AT6400 Installation Guide
Trigger Inputs
AUXILIARY
TRIGGERS
TRG-x connected to GND (normally-open switches).
The active level (default is active low) can be changed
with the INLVL command.
These inputs are like the general-purpose inputs on the
50-pin header. The differences are (1) the triggers are
pulled up via the AUX-P pull-up terminal; and (2) the
triggers can be programmed with the INFNCi-H command
to function as position capture inputs (encoder & motor
position is latched within 50µs) and registration inputs.

Pr5V power to the TRG input pull-up resistors (the AT6n00 is
shipped from the factory wired in this configuration). As an alternative,
you can connect AUX-P to an external power supply of up to 24VDC.
NOTE: AUX-P is also the pull-up for POS, NEG, HOM, & P-CUT inputs.
SINKING CURRENT: To make these inputs sink current, connect AUX-P
to GND.

If you will be connecting to a combination of sourcing and sinking outputs,
connect
AUX-P
to
+5V
to accommodate sinking output devices. Then for each
individual input connected to a sourcing output, wire an external resistor between
the AT6n00's trigger input terminal and ground (see illustration). The resistor
provides a path for current to flow from the device when the output is active.
PROGRAMMING TIP
Connecting to a sinking output? Set the trigger input's active level to low
with the
INLVL
command (
Ø
= active low,
default setting).
Connecting to a sourcing output? Set the trigger input's active level to
high with the
INLVL
command (
1
= active high).
Thus, when the output is active, the
TIN
status command will report a “
1
”
(indicates that the input is active), regardless of the type of output that is
connected.
For details on setting the active level and checking the input status refer to the
INLVL
and
TIN
command descriptions in the
6000 Series Software
Reference Guide.
