Features:
- The converter control suffix links CU2 to the applicable Vector Control unit records.
- A10 provides the chassis position used to locate the control board.
- The CU2 order is referenced in both AC-fed and DC-fed converter lists.
Start with the complete converter order code before using the control suffix as a CU2 check.
Use A10 to confirm the physical board position after the converter family has been identified.
Treat the supply section as chassis context; it does not change the 6SE7090-0XX84-0AF0 control-board identity.
The Siemens 6SE7090-0XX84-0AF0 CU2 Control Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

CU2 Control Relationship
- Control scope: Open-loop and closed-loop functions are combined on the CU2 rather than split between separate boards.
- System role: The board belongs to the Vector Control path within SIMOVERT MASTERDRIVES.
- Software context: Version 1.34 forms part of the CU2 configuration record for this order.
- Location check: A10 identifies the control-board position after the correct converter has been established.
Communication and Output Group
- Shared connector: X100 carries the RS485 path and binary-output functions on the same terminal block.
- Reference conductor: The external RS485 reference must be traced with the receive and transmit pair.
- Record keeping: Communication conductors and output contacts should remain separate in the wiring record.
- Conversion use: X100 terminals are matched to CUVC by function rather than by terminal number alone.
Supply and Input Group
- Supply relationship: P24 and M24 feed the binary-input group located on X101.
- Input organization: BI1 through BI7 share this terminal area with their reference connections.
- Checking boundary: Supply presence and individual input conductors remain separate checks even though both appear at X101.
- Wiring check: Preserve the reference and repeated supply terminals when documenting the installed CU2.
Function-Based Conversion
- Mapping principle: CU2 and CUVC connections correspond by function, not by equal terminal number.
- Floating outputs: EB2 supplies the required arrangement when isolated digital outputs must be retained.
- Relay path: A floating relay changeover also moves through the EB2 expansion arrangement.
- Operating sets: CU2 basic and reserve changeover functions correspond to two CUVC BICO data sets.
