Infinity™ Series Servo Ultrasonic Press Systems QUICK START GUIDE
Explanation
Problem with incoming AC line voltage.
Generator has exceeded its temperature
limit.
The operating frequency was artificially
bounded by the system frequency limits for
25 consecutive milliseconds. This is usually
due to excessive operating frequency drift
(operating frequency is "far" from free run
frequency) due to heating of the stack.
One of several possible problems detected
on servo controller.
Large amount of force was applied for an
excessive amount of time while jogging.
Servo press was not able to complete the
programmed motion due to reaching its
maximum force capability.
Indicates a problem with the servo amplifier.
Servo controller program error.
Internal servo controller error.
Lower travel limit switch was activated on
press.
Upper travel limit switch was activated on
press.
A failure has been detected during the
servo hardware test, which is performed at
system startup or reset.
The servo actuator temperature has exceed-
ed 100° C.
Solution
Verify that the incoming AC Line voltage supplied to the
generator is within the range specified for the generator.
Consult the manual for your generator
Check for blockage of air vents on the sides of the gen-
erator, restricting air flow to the inside of the generator.
Check if the internal fan is defective.
Execute the following steps to alleviate the problem:
Observe the last operating frequency from a test graph.
Enable "Advanced Process Settings".
Change "System Frequency Limits" to "Manual" and
adjust the offending upper/lower frequency limit to an
acceptably safe value for your horn/stack/application.
Often as a horn/stack heats up, it may begin to have
trouble starting (Frequency Overload Fault 1) because
the operating frequency is drifting away from the gener-
ator's Free run Frequency setting.
Adjusting the Free run Frequency may also be advis-
able. A sudden shift in frequency (as observed on the
graph) immediately before a Frequency Overload Fault
3, as opposed to a general frequency drift, indicates
stack/horn coupling to the part during the weld or an
another abrupt change in stack resonance. This does
not imply an operating frequency drift issue, but a weld
application setup issue.
Cycle power on the generator.
If alarm persists, contact Dukane.
Cycle power on the generator.
Do not apply large force for long periods of time while
in jog mode.
Decrease trigger force, weld and/or hold speed(s).
Use alternate press model with larger force capacity.
Cycle power on the generator.

If alarm persists, contact Dukane.
Jog the press up to avoid contact with the limit switch.
Jog the press down to avoid contact with the limit
switch.
Press any key on generator color display for additional
failure details.
Check that servo AC breaker is on and the servo power
LED on the press is lit.
Check that all cables are connected securely.
Check for any damage to connector pins.
If alarm persists, contact Dukane.
Turn servo press off, wait for actuator to cool down,
then resume operation.
Increase time between cycles to prevent excessive
heating.
