Error Message:

DRUM: Timeout waiting for drum move

Applies to:

• All

Service Information:

Command was issued to move drum to position but it did not read at the position within the time that it should take to accelerate (to specified move speed) do one revolution and decelerate (plus 50% margin).

Or a monitor command (example DRUM MOVE T 12000) was given to Torque to a position, which applies torque till the drum reaches the postion then idles the drum with the dynamic (regenerative) brake on. The max time allowed for this is the same as above.

Check lower level commands such as "drum spin <speed>", "drum spin 60 c", or do a drum torque test.

Operator Action:

If it occurs repeatedly then call Creo service

Cause:

• Probable drum amp deadband calibration problem.
• Possible encoder problem; dirty disc or encoder laser, cabling or alignment.
• Possible corrupt NVS weight position values under set state al "wp1", "wp2". (Use "bal find" to remedy problem.)
• Possible firmware bug if this only happens during unloading a workstation plot.
