Error Message
Description
Cause(s)
Possible Solution(s)
Overload (average) at xxx msecs. Power above generator rating.
Power from ultrasonic stack sent to the part exceeds power rating of generator
.
1. Excessive pressure applied to the part. 2. Booster size is too large.
1. Decrease pressure applied to part. 2. Reduce size of booster

nant frequency of the ultrasonic stack.
1. Improper stack assembly
.
2. Defective ultrasound cable. 3. Ramp up time is too short.
1. Disassemble and reassemble stack. 2. Replace ultrasound cable. 3. Increase ramp up time.
Overload (frequency) at xxx msecs. Check for coupling between stack and part.
Generator correctly locks to the resonant frequency of the ultrasonic stack, but loses the lock at a point later in the weld cycle.
Horn comes in contact with the part nest or anvil.
Make adjustments to thruster and part nest.
