Tweco HMC-410 Robotic Interface Kit - Manual (Page 17)

Pin Name Description
E Contactor When the robot control puts +24 VDC on this line with respect to pin J,
the HMC-410 will close the contactor on the power source it is attached
to, producing an output voltage on the output terminals.
F Wire On When the robot control puts +24 VDC on this line with respect to pin J,
the HMC-410 will run the wire at the speed set in the INCH SPEED win-
dow on the HMC-410. If EEE is selected for INCH SPEED, the speed
will be set by the voltage on pins W and X.
G Gas On When the robot control puts +24 VDC on this line with respect to pin J,
the HMC-410 will purge the gas lines.
H Unused
J Common Robot Common
K Inch Feedback This line is set to +24 VDC with respect to pin J by the HMC-410 when
the HMC-410 Inch controls are activated. The purpose of this line is to
tell the robot to return inch speed command voltage on pins W and X
when the HMC-410 is inching wire locally.
L Weld Inhibit This line is set to +24 VDC with respect to pin J by the HMC-410 when
the HMC-410 is in test (dry run) mode.
M Weave Inhibit This line is set to +24 VDC with respect to pin J by the HMC-410 when
the operator wants to run an arc with the robot’s weave mode disabled.
N Wire Stuck This line is set to +24 VDC with respect to pin J by the HMC-410 when
the HMC-410 senses a wire stuck.
P Welder Ready This line is set to +24 VDC with respect to pin J by the HMC-410 when
the HMC-410 is ready to weld.
Q +24 VDC Robot +24 VDC
R Unused
S Unused
T Unused
U Unused
V Unused
W WFS - Analog return
X WFS + This line is a 0 to 10 VDC analog signal, which corresponds to a 0 to 888
inches / minute wire feed speed.
