Alarm Code
Alarm Message
Explanation
Solution
U401
Weld Time set to Zero
Adjust weld time to be greater than zero.
U402
Weld Power set to Zero
Adjust weld peak power to be greater than zero.
U403
Weld Energy set to Zero
Adjust weld energy to be greater than zero.
U404
Weld Distance set to Zero
Adjust weld distance to be greater than zero.
U405
Weld Position set to Zero
Adjust weld position to be greater than zero.
U406
Max Trigger Time set to
Zero
Adjust maximum trigger time to be greater than zero.
U407
Forced Shutdown Alarm
External command was received by genera
-
tor to end weld cycle.
This alarm is for information only.
U410
Pre-trigger Overtravel
Alarm
Press travel exceeded fixed distance limit
while ultrasound was active.
For servo press the distance from pre-trigger to position
of trigger is required to be less than 0.25 inches or 6.35
millimeters.
For pneumatic press the distance from pre-trigger to
position of trigger is required to be less than 0.75 inch
-
es or 19.05 millimeters.
U411
Part Detected Too Early
Contact between the horn and part was
detected before reaching the Sensing Start
Position.
Adjust Sensing Start Position to be above contact with
part. Account for variation of heights of unassembled
parts.
NOTE: repeated occurrences of this alarm may result in
costly damage to servo actuator.
U413
Max Trigger Time Ex
-
ceeded
Trigger did not occur within the specified
time limit.
Increase maximum trigger time.
Start the weld process sooner.
U414
Max Trigger Delay Time
Exceeded
Trigger delay distance was not reached
within the specified time limit.
Increase maximum trigger delay time.
Start the weld process sooner.
U500
Servo Must Be Homed
The servo press must complete the homing
process before operation is allowed.
Home the servo press by activating both operating
switches.
U501
End of Weld Signal
Detected
When Auto-stop is enabled and set for End
of Weld, this alarm indicates that the signal
has been detected.
This alarm is for information only.
U502
End of Cycle Signal
Detected
When Auto-stop is enabled and set for End
of Cycle, this alarm indicates that the signal
has been detected.
This alarm is for information only.
U505
Transducer Door Open
Sonics does not run when the transducer
door is open.
Reinstall transducer door before running sonics.
