Position Error

Allowable servo position following error  was exceeded.

1. Force required to maintain pro

-

grammed speed(s) is too large. 2. 

Trigger Distance or Sensing Start 

Distance is too large, causing premature  contact of horn with part. 3. Press motion is obstructed.

1a. Reduce weld/hold speed(s). 1b. Increase weld amplitude to increase melt  rate. 2. Reduce 

Trigger Distance or Sensing start 

Distance. 3. Check for and remove any obstructions to  press motion.

Servo Error

General servo error

.

Multiple causes possible.

1. Restart press system. 2. Contact DUKANE service.

Trigger<Sensing Start  Distance

Force or Power 

Trigger occurred before 

press reached Sensing Start Distance.

1. Sensing Start Distance is too large. 2. Part(s) not properly loaded.

1. Decrease Sensing Start Distance. 2. Check part placement.
