6SE7090-0XX84-0KA0 | SIMOVERT MASTERDRIVES ADB Adapter Module — Optional Board Mounting Carrier / Compact + Chassis Drives / Discontinued September 2020

The ADB Is the Prerequisite — Everything Else Depends on It

Within the SIMOVERT MASTERDRIVES optional board architecture, there is a strict installation order: the ADB (Adapter Drive Board) must be fitted inside the drive before any optional expansion board can be installed. The ADB is not an optional board itself — it is the mounting platform on which optional boards are physically seated and electrically connected to the drive's control circuit.

Without the ADB, none of the MASTERDRIVES miniature-format optional boards — the EB1 terminal expansion board, the EB2 floating output board, the SBP encoder evaluation board, or the CBP2 PROFIBUS board — can be mechanically installed or electronically recognised by the drive. The ADB provides both the physical PCB slot connectors and the internal bus connection that transfers signals between the optional board and the drive's CUVC or CUMC control unit.

This dependency means that when planning a first-time optional board installation on a MASTERDRIVES drive that has never had options fitted, the ADB order number must appear alongside the optional board order number in the bill of materials.

Key Specifications

ADB in the MASTERDRIVES Optional Board Hierarchy

The MASTERDRIVES optional board family follows a clear parent-child structure:

6SE7090-0XX84-0KA0 — ADB (this module): The carrier board. Installed once per drive. Provides slot connectors for up to two miniature-format boards. Connects to the drive's control unit via internal bus interface. No signal processing function of its own.

Optional boards that mount on the ADB:

• EB1 (6SE7090-0XX84-0KB0): Terminal expansion — additional referenced digital I/O
• EB2 (6SE7090-0XX84-0KC0): Terminal expansion — floating outputs, relay changeover contact, analogue I/O
• SBP (pulse encoder board): Incremental encoder evaluation for speed and position feedback
• CBP2 (PROFIBUS board): PROFIBUS DP communication interface for drive parameterisation and cyclic data exchange

A single ADB supports up to two of these boards simultaneously, in any combination that fits the available slot positions. The most common configurations are ADB + EB2 (for I/O expansion), ADB + CBP2 (for PROFIBUS), and ADB + CBP2 + EB2 (for both).

Application Scenarios

First-time PROFIBUS expansion: A MASTERDRIVES compact drive requires PROFIBUS DP for integration into an S7-based network. Order: 6SE7090-0XX84-0KA0 (ADB) + 6SE7090-0XX84-0BP0 or CBP2 PROFIBUS board. Install the ADB first; then fit the CBP2 into the ADB slot.

I/O expansion on a drive without options: A chassis drive requires additional floating digital outputs for external status reporting and a relay contact for fault indication. Order: ADB + EB2. The ADB enables the EB2 to mount and communicate.

Adding a second option to an existing ADB installation: A drive already has a CBP2 fitted on an ADB. A second EB2 is needed. The ADB is already installed — add only the EB2 to the available second slot.

FAQ

Q1: Must the ADB be removed when replacing optional boards already installed on it?

The optional board plugs into the ADB's slot connector. When replacing an optional board, the ADB itself stays in place — only the defective optional board is removed and the replacement is inserted. The ADB only needs to be removed if the ADB itself has failed, which is uncommon.

Q2: Can the ADB be installed while the drive is powered?

No. All work inside the MASTERDRIVES electronics compartment — including installing or removing the ADB or any optional board — must be carried out with the drive fully de-energised and the DC bus discharged. Observe ESD precautions when handling circuit boards.

Q3: How is it confirmed that the ADB and optional boards are correctly recognised after installation?

After power-up, DriveMonitor or STARTER displays the optional board configuration in the drive parameter list. The CBP2 PROFIBUS board appears as an active slave node; the EB2 terminal board shows its I/O terminals available for BICO parameterisation. An optional board that is not recognised indicates a seating fault or connector issue at the ADB.

Q4: Is there a difference between the ADB for Vector Control and Motion Control variants?

The 6SE7090-0XX84-0KA0 is applicable to both SIMOVERT MASTERDRIVES Vector Control (VC) and Motion Control (MC) compact and chassis drives. The same ADB part number covers both control board variants. The optional boards plugged into the ADB may differ between VC and MC drives depending on the application — verify optional board compatibility with the specific drive type from the MASTERDRIVES optional board documentation.

Q5: What is the cross-reference between 6SE7090-0XX84-0KA0 and 6SX7010-0KA00?

Both numbers identify the same ADB board. The 6SE7090-0XX84-0KA0 is the drive system catalog number used for ordering; the 6SX7010-0KA00 is the spare parts cross-reference designation. Searching both numbers in aftermarket inventories increases the chance of locating available stock for this discontinued item.
