Tweco HMC-410 Robotic Interface Kit - Manual (Page 16)

The inputs can accept inputs from 5 to 24 Volts, AC or DC.
Operation
The kit uses 2 soft-switches for robotic mode selection (ROB) and wire stick check enable (ELS). The ROB
soft-switch dictates the operational characteristics of the system and thus is fairly involved. The following
chart can be used to help identify which mode is required for a particular setup.
Robot Configuration Recommended HMC-410
Robotic Mode
ABB Direct Control of Wire, Voltage, and Gas 1 (or 4 for 1V in is 5 Arc
Volts, 100 IPM Scale)
ABB Master Weld On/Off style control. Welder controls things like
preflow, burnback, and postflow times and some or all wire
feed speed and arc voltage settings.
2 (or 5 for 1V in is 5 Arc
Volts, 100 IPM Scale)
Fanuc Master Weld On/Off style control. Welder controls things like
preflow, burnback, and postflow times and some or all wire
feed speed and arc voltage settings.
3
Comau Master Weld On/Off style control. Welder controls things like
preflow, burnback and postflow times and some or all wire
feed speed and arc voltage settings.

Details on these different modes are provided in the appropriate section under the Robotic Mode Selection
softswitch section for each ‘mode’.
Robotic Mode Selection (ROB):
This soft-switch selects if the robotic mode is being used, and if it is what mode is selected. The following
modes are supported:
OFF: Operates as standard 410, robotic interface is disabled.
1 (and 4): This mode selects the ABB direct control. When used with the 24 Pin Amphenol Board (870213),
the following signals are supported:
Pin Name Description
A Water / Gas
Error
A loss of adequate water (cooling) or shielding gas is designated when
this line is shorted to pin J.
B Arc
Established
The welder supplies +24 VDC with respect to pin J when an arc is estab-
lished.
C Inch Reverse When the robot control puts +24 VDC on this line with respect to pin J,
the HMC-410 will run the wire in reverse at the speed set in the INCH
SPEED window on the HMC-410. If EEE is selected for INCH SPEED,
the speed will be set by the voltage on pins W and X.
D +24 VDC Robot +24 VDC
