Description
Instructions
Internal machine error
Internal machine error
Internal machine error
1 . Press is jogged in a way to
produce a force on the parts
larger than allowed in jog
mode (most common cause)
2 . Servo system feedback is
malfunctioning
Operator pressed E-stop switch
1 . No part present to pick up
2 . Loss of vacuum between part
and tool
1 . Part not present
2 . Problem with sensor
Switches were released after weld
cycle started but before the spin
motor stopped
Internal machine error
Internal machine error
1 . Import procedure problem
2 . Cable problem
3 . Machine component failure
1 . Tooling inertia entered is
outside allowable range
2 . Servo tuning database is
missing
1 . Air pressure to slide too low
2 . Slide limit switch improperly
positioned
3 . Slide jammed
Internal machine error
Weld time or number of rotations
too large

Possible Solution

1 . Check for obstructions to motion
outside welder
2 . Contact DUKANE service
Contact DUKANE service
Contact DUKANE service
1 . Prevent press from applying a large
force on the parts in jog mode
2 . Contact DUKANE service
Reset E-stop switch then reset machine
1 . Ensure part is present for pickup
2 . Check vacuum between part and tool
(line connections, vacuum generator,
tool wear)
1 . Ensure part is present
2 . Troubleshoot sensing components
Once weld cycle is started, ensure switches
remain activated until spin motor stops (i .e .
at beginning of hold phase)
Contact DUKANE service
Contact DUKANE service
1 . Contact DUKANE for import
procedure
2 . Check that the correct cable is used
and that it is securely connected
3 . Contact DUKANE service
1 . Enter tooling inertia within limits stated
in this manual
2 . Contact DUKANE regarding importing
servo tuning database
1 . Increase air pressure
2 . Adjust slide switch position
3 . Ensure slide can move freely
Contact DUKANE service
Reduce weld time, distance, or number of
rotations
