By default, the trigger inputs are sourcing inputs. If you wish all of the
trigger inputs to sink current, connect "TRIG-P" to "GND" on the
screw-terminal connector located on top of the 6K chassis.

•
Voltage range is 0-24VDC.
•
Trigger input s
witching levels:
Low
≤
1/3 VINref voltage, High
≥
2/3
VINref voltage (factory default VINref
voltage is +24VDC, but you can
connect a different voltage to the
VINref terminal**). To make all limit
inputs sinking inputs, connect the
TRIG-P terminal** to the GND
terminal**.
•
Status: Check with
TIN
or
IN
.
•
Programmable functions with the
INFNC
command. Can also be used as
a “Trigger Interrupt” input (
INFNCi-H
)
for position capture and registration.
•
Active level is set with the
INLVL
command. Default is active low (see
n.o. switch in diagram above).
•
Open collector output;
will sink up to 300mA.
•
Status: Check with
TOUT
or
OUT
.
•
Programmable
functions with the
OUTFNC
command. Can
also be used as an
“Output on Position”
output (
OUTFNCi-H
).
•
Active level is set with
the
OUTLVL
command.
Default is active low.
•
If the outputs are
driving inductive loads,
connect the OUT
DIODE terminal to
24VDC.
* All even number pins are connected to isolated logic ground.
** The VINref, TRIG-P, and GND terminals are located on the screw-terminal connector on top of the 6K chassis.
Master Trigger: The “MASTER TRIG” input on this
connector has the same circuit design as trigger
inputs on the “TRIGGERS/OUTPUTS” connectors.
For easy screw-terminal
connections, use the “VM25”
screw-terminal converter (sold
separately, includes 2-foot
cable). Connection instructions
are provided on page 41.
