Tweco HMC-410 Robotic Interface Kit - Manual (Page 19)

Pin Name Description
F Wire On When the robot control puts +24 VDC on this line with respect to pin J,
the HMC-410 will feed the welding wire. If the power source contactor is
on or the INCH SPEED window is programmed to EEE, the speed is set
by the robot. Otherwise, the speed is set in the INCH SPEED window.
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.
Y VOLT - Analog return
