Error Message:

DRUM: Drum Position error during Velocity mode, (check acceleration setting)

Applies to:

• All

Service Information:

While the drum was spinning, or accelerating/decelerating to velocity, the position error was greater than allowable. The allowable error is 500 ticks plus an extra factor based on the acceleration.

This error is most likely due to the drum amp not being able to meet the requested acceleration - either because the acceleration is too high, or because there is something wrong with the drum amp. It could also be caused by the encoder reporting the position incorrectly.

Operator Action:

Resume and report to Creo Response center.

Cause:

• Invalid acceleration setting
• Faulty drum amp
• Dirty encoder, faulty index, misaligned encoder.
