Siemens 6SE7090-0XX84-0AF0 CU2 Vector Control Board
A SIMOVERT MASTERDRIVES CU2 control board whose catalog number and installed drive record define the service boundary.
Technical Summary
Siemens 6SE7090-0XX84-0AF0 identifies the CU2 control board used in SIMOVERT MASTERDRIVES vector-control equipment. In Siemens component documentation the CU2 occupies the A10 control position.
Service suitability depends on the complete converter MLFB, CU2 hardware execution, parameter backup, option boards and motor-feedback arrangement. Similar MASTERDRIVES control boards are not automatic substitutes.
Siemens documents a defined changeover path from CU2 to CUVC; that conversion requires the applicable manufacturer instructions rather than a board-only exchange.

Features
Closed-loop control role
The board carries the drive control functions associated with the CU2 vector-control execution.
Parameter-dependent identity
Commissioned behavior is tied to the stored drive parameter set and connected feedback hardware.
Option-board coordination
Installed option modules and communication interfaces must remain aligned with the control configuration.
Legacy migration boundary
A later CUVC arrangement may require different hardware and documented conversion steps.

FAQ
Is 6SE7090-0XX84-0AF0 interchangeable with any MASTERDRIVES control board?
No. The CU2 execution, converter MLFB, parameter structure, option boards and feedback interfaces must be reviewed together.
What backup should be prepared before removing 6SE7090-0XX84-0AF0?
Preserve the full parameter set, fault history, motor and encoder data, communication settings and photographs of every board and connector.
Does a CUVC board plug directly into a 6SE7090-0XX84-0AF0 installation?
Do not assume a direct exchange. Siemens provides a specific CU2-to-CUVC changeover guide with hardware and commissioning requirements.
Which label evidence is useful for a 6SE7090-0XX84-0AF0 enquiry?
Send the complete drive nameplate, CU2 label, control-panel type, option-board labels and the converter circuit-diagram reference.
How should a serviced 6SE7090-0XX84-0AF0 drive be accepted?
Confirm parameter integrity, control supply, feedback plausibility, direction, current limits, communications and the approved machine-safety sequence.
