Drive line voltage less than 432 Vac (480 Vac - 10%) for more than 1 second when
not welding.
Solution:
Monitor incoming power line voltage.
Reduce welding force to lower load on the drive.
The Vacuum Sensor could not detect the parts to be welded.
Solution:
Home the machine, reposition the parts, and try welding again.
Valve x: Start and stop method cannot be set to "Start of Weld".
Solution:
Change your selections for start and stop method so they are not the same.
The load has exceeded the drive's capability.
Solutions:
Increase the feedback delay to 3 seconds.
Check your weld force; it could be set too high for the application. For example,
4000 lbs of weld force could restrict horizontal displacement, essentially stalling
the machine.
Check the tool for proper alignment. If misaligned, the weld bead will not have
adequate space to move freely, causing a stall condition.
Check that tool stanchions are in the retract position.
Auto-tune the system.
Verify that all 12 mm bolts attaching the tool to the machine are installed and
torqued to 100 foot pounds.
Check that all bolts on the tool are tightened to the manufacturer's
specification.
Check the weight of the tool and make sure it's within range for the machine.
VW6300: between 20 - 55 lbs
VW6700: between 90 - 150 lbs
VW6900: between 110 - 200 lb
VW LPT 6960: between 60 - 180 lbs
Weld time has expired before weld distance could be achieved.
