Siemens 6SE7090-0XX84-0AH2 SIMOVERT MASTERDRIVES T300 Module

Legacy T300 technology module for application-specific SIMOVERT MASTERDRIVES functions

Siemens identifies 6SE7090-0XX84-0AH2 as a spare T300 module for the discontinued SIMOVERT MASTERDRIVES platform. Its suitability depends on the installed drive family, T300 application software, board revision, connector arrangement and saved machine configuration.

Before you orderMatch the complete article and board revision, drive type, T300 software or EPROM state, parameter backup, connector map and installed accessories before purchase; do not substitute the T300 retrofit kit article without checking scope.

Compatibility

A visual match is not enough for a legacy T300 exchange; the drive, application and delivery scope must agree.

Board identity

Photograph the complete article number, board revision, option labels and installed memory or application devices before removal.

Application state

Save the drive and T300 parameter data and identify the machine-specific technology application and software version.

Accessory scope

Check whether SC58 and SC60 leads and the SE300 terminal block remain serviceable or must be included in the replacement plan.

Description

6SE7090-0XX84-0AH2 belongs to the SIMOVERT MASTERDRIVES T300 technology-board system. Siemens lists the exact article as a discontinued spare part, so procurement and commissioning should be based on the installed nameplate and archived machine documentation.

The official SIMOREG documentation separately lists a T300 package with two connecting leads, SC58 and SC60, a terminal block SE300 and hardware instructions. Confirm which accessories are already installed because a board-only replacement and a complete package are not the same delivery scope.

Service Checks

Use a controlled electrical and functional sequence so a configuration or connector fault is not mistaken for a bad replacement board.

Safe isolation

Follow the MASTERDRIVES shutdown procedure, verify the DC link is discharged and use ESD controls before touching the module.

Connector map

Label every connector and terminal, inspect pins and cable strain, and reinstall each lead in the documented position.

Acceptance test

Restore the approved data, review diagnostics and test the technology function at a safe operating point before production release.

FAQ

Q1

Can 6SE7090-0XX84-0AH2 be selected as a direct replacement only because the installed option board is marked T300?

No. Verify the complete article number, memory-module label, board revision, host SIMOVERT MASTERDRIVES unit, option-slot configuration and machine-specific T300 application. A generic T300 board or a board carrying different application memory may fit mechanically but will not necessarily reproduce the original machine function.

Q2

What information should be backed up before removing 6SE7090-0XX84-0AH2 from an operating drive?

Save the complete drive parameter set and the T300 application or STRUC project when available. Record the memory-module or EPROM identification, application version, encoder settings, analog and digital I/O assignments, serial-interface settings, scaling values and terminal map. Photograph the board, memory module and every cable before disconnection because a basic drive backup may not contain all T300-specific data.

Q3

Why can the host drive become ready after 6SE7090-0XX84-0AH2 is installed while the T300-controlled machine function remains unavailable?

Confirm that the correct memory module and machine application are installed, that the board is recognized in option slot 2 and that every external T300 connection matches the original terminal documentation. Inspect the screened cables, connector orientation and SE300-side wiring where that terminal system is used. Test each required technology signal before modifying parameters or application software.

Q4

What should be checked if encoder or positioning feedback becomes unstable after installing 6SE7090-0XX84-0AH2?

Verify the encoder type, supply, pulse count, channel polarity, cable shielding, grounding and connector condition. Compare the T300 scaling, direction and limit settings with the archived application. Perform the first test at a controlled low-risk operating point and monitor the feedback signal before enabling the complete positioning or technology function.

Q5

How should 6SE7090-0XX84-0AH2 be removed or installed safely in a SIMOVERT MASTERDRIVES unit?

The work must be performed by qualified drive-service personnel. Isolate every power source, observe the specified DC-link discharge time, prove absence of voltage and apply ESD protection. Never insert or remove the board while voltage is present. Install the technology board only in the approved option slot and verify all connectors before the converter is energized.

Q6

Is 6SE7090-0XX84-0AH2 appropriate for a new machine design or modernization project?

It should normally be treated as an exact-match legacy spare, not as the default choice for a new design. Siemens classifies the product as phased out or discontinued, available only while stock remains with conditional repair, and not RoHS-compliant. Before using it in a modernization project, confirm the destination-market compliance requirements and obtain an engineered migration recommendation for the drive and its machine-specific T300 application.
