Message Description Cause Possible Solution
Spin motor not on
Spin servo amplifier does
not power up
Internal machine error Contact DUKANE service
Spin servo amplifier faulted
There is a problem with the
spin servo amplifier
1 . Excessive spin deceleration
2 . Excessive press weld or hold
speed
3. Amplifier disabled due to
excessive temperature
4. Amplifier failed
1 . Reduce deceleration
2 . Reduce speed(s)
3 . a) Reduce machine duty cycle
b) Ensure temperature around
machine is within operational limits
4 . Contact DUKANE service
Spin servo tracking error
The spin servo motor
was not able to execute
the spinning motion
programmed in the setup
1 . Excessive press weld or hold
speed(s)
2 . Excessive spin deceleration
3 . Joint weld diameter too large
4 . Improper tuning
1 . Reduce speed(s)
2 . Reduce deceleration
3 . Use welder model with larger spin
torque capability
4 . Ensure correct tool inertia is entered
in touch screen
Spin weld axis aborted
Expected spin servo move
was not completed
Internal machine error
1 . Check for obstructions to motion
outside welder
2 . Contact DUKANE service
Timeout on servo CPU
Thread 1(thrd1)
Motor controller error Internal machine error Contact DUKANE service
Timeout on servo response
to command start Servo system
communication error
Internal machine error Contact DUKANE service
Vertical at travel limit
Press travel distance
exceeded controller
counting capability
Press travel too large
Reduce weld time / distance / number of
rotations, or hold distance
Vertical motor not on
Vertivcal servo amplifier
does not power up
Internal machine error Contact DUKANE service
Vertical servo amplifier
faulted There is a problem with the
vetical servo amplifier
1. Amplifier disabled due to
excessive temperature
2. Amplifier failed
1 . a) Reduce machine duty cycle
b) Ensure temperature around
machine is within operational limits
2 . Contact DUKANE service
Vertical servo tracking error
The vertical servo actuator
was not able to execute the
press motion programmed
in the setup
Excessive press weld or hold speed Reduce speed(s)
Vertical weld axis aborted
Expected vertical servo
move was not completed
Internal machine error
1 . Check for obstructions to motion
outside welder
2 . Contact DUKANE service
Weld trigger position is
below vertical travel lower
limit Cycle will not start since the
programmed press travel is
larger than the set limit 1 . Vertical travel lower limit set
too high
2 . Trigger position too large
1 . Lower vertical travel lower limit, if
possible .
2 . Decrease Trigger position
