0042-6848 - Ultra3000 control board (VUTEk QS servo drive)

Electronic board (ECN) — 10010267

The electronic board (ECN, 10010267) is fitted to VUTEk printers. It provides the electronic control of a machine sub-system and passes the signals to the control board.

The board label reads "ASSY 0042-6848" and "ECN 100102677": the catalogue number 10010267 is this Engineering Change Notice number, the assembly reference is 0042-6848 and the printed circuit board is silk-screened AW0016-6563 rev 02. This numbering belongs to Allen-Bradley (Rockwell Automation, formerly Electro-Craft / Reliance Electric): it is the control board of an Ultra3000 servo drive (2098-DSD series), the axis drive that the VUTEk QS range carries under reference P7886-A (Ultra 3000 SERCOS 10 A / 30 A).

Compatibility & use

• VUTEk QS2 Pro
• Check the exact index on the original drive (10 A or 30 A rating, SERCOS or DeviceNet version) before replacement: the precise variant of board 0042-6848 is not documented online
• Fits inside the Ultra3000 drive, not directly in the printer

Function

• Control logic of the axis servo drive: receives the setpoints from the bus, reads the motor encoder feedback (CN2) and drives the power board (J3)
• Manages the isolated control inputs / outputs (CN1), the output relay and the status code display
• Provides the electronic control of a sub-system
• Passes the signals to the control board
• Acts as the interface between firmware and hardware

Signs of wear

• Axis drive showing a fault code or remaining without status at start-up
• Axis not servo-controlled, motor not powered while the power board is sound
• Loss of drive communication on the bus
• Sub-system not driven
• Electronic errors
• Loss of internal communication
• Erratic behaviour or machine stops

Replacing this part restores the machine to proper working order.
