Rexroth CSB02.1A-ET-EC-NN-NN-NN-NN-FW CSB Control Section R911338329

Rexroth CSB02.1A-ET-EC-NN-NN-NN-NN-FW CSB Control Section R911338329

The CSB02.1A-ET-EC-NN-NN-NN-NN-FW, material reference R911338329, is listed as a Rexroth IndraDrive CSB control section for maintenance and spare-part sourcing for installed drive systems. The complete configuration is retained to help overseas buyers match an original machine requirement. Public catalog records support the model and material-number association; the actual offered nameplate, hardware index and included components must still be checked for each quotation.

Product identification and attributes

Exact communication and feedback configuration

CSB02.1A is recorded as basic interface scope. The requested master communication is ET: Multi-Ethernet. Interface 1 is EC: multi-encoder interface, while interface 2 is NN: not equipped. These fields are retained separately because changing an encoder or communication option can change the machine integration requirements.

The CSB is a control section used within a drive arrangement. The quotation concerns the identified control section, rather than a complete power converter, supply unit or motor. If a complete assembled drive is required, provide the power-section designation as well. Interface labels and port positions should be checked against the original equipment. A shared CSB family name, similar enclosure or matching connector count does not establish interchangeable operation.

Safety option and firmware requirements

The NN safety field records that no optional safety interface is specified in this complete designation. Do not assign STO or Safe Motion capabilities from a different CSB variant to this unit. Match the original machine safety arrangement and the precise control configuration.

The FW suffix means firmware is ordered as a separate subposition. It is not an assurance that a particular firmware version, license or machine project is included. Provide the original firmware designation and version, parameter backup and any essential project or memory requirement. An operating panel or removable medium is supplied only when identified in the quotation. Preserve the final suffix exactly; FW, AW and NW descriptions must not be silently merged.

Replacement matching and enquiry checklist

Send a clear front-on photograph of the complete original type plate, including the model, R911 material number, serial number and hardware index. Include the firmware identification, the connected power-section type and your machine spare-parts reference. Add photographs of the front, connection areas and any removable accessories when completeness is important. A partial model copied from a purchase record may omit an essential option or design field.

State the installed communication network and the original encoder arrangement. Record which plugs, control panel, covers, removable memory and mounting accessories are required. The buyer’s responsible technician should compare the proposed control section with the applicable documentation and machine configuration before accepting a replacement. Differences between fixed and configurable versions, interface scope, design generation and optional safety hardware should be reviewed individually.

A replacement enquiry should also identify the required quantity, destination and acceptable condition. If an alternative is proposed, obtain its complete model, material number and hardware index before assessing suitability. An alternative quotation should document the differences rather than describing every CSB model as equivalent. This listing does not guarantee compatibility with another configuration, firmware release or power section.

Condition and genuine spare-part sourcing

This page is a genuine original spare-part enquiry for maintenance of installed systems, including legacy installations. It does not assert that every listed CSB variant has been discontinued. Tell us whether unused surplus, previously used equipment or another condition is acceptable. The actual quotation will identify the proposed unit, its stated condition and the items included. Available inspection or test information applies to that unit only.

For stored or previously operated control sections, service history and inspection records can help assess a sourcing proposal. Exterior appearance alone does not confirm functionality, correct firmware or readiness for commissioning. Request any essential checks or documents when sending the enquiry so their availability can be assessed. No fixed testing scope, warranty period, manufacturer authorization or official agency relationship is implied.

Budget price and quotation

The displayed USD 879.76 per piece is a same-model eBay budget reference, calculated at 65% of an observed asking price of USD 1353.48 for CSB02.1A-ET-EC-NN-NN-NN-NN-FW. The complete model matches the reference, but condition, accessories and firmware arrangements still require separate confirmation. The reference seller’s stock, condition, testing, warranty and delivery promises are not transferred to this listing.

Request CSB02.1A-ET-EC-NN-NN-NN-NN-FW, catalog reference R911338329, with the original label photographs and the required components. Availability, actual condition, final price, included firmware or accessories, freight and applicable charges are confirmed case by case. An observed asking price is not a confirmed transaction price or a binding supply offer.

Ordering and delivery

Minimum order quantity is 1 piece. The supply target is 10 pieces per month, subject to actual availability. If an in-stock unit is confirmed, dispatch is normally within one week; non-stock sourcing and lead time are agreed separately. Payment terms and protective export packaging are confirmed with the quotation. Include the required arrival date before planning a maintenance shutdown.

Frequently asked questions

Is this a complete servo drive?
This page identifies a CSB control section. A power section, motor and other system components require their own identification and quotation.

Is firmware included?
FW requires a separately identified firmware subposition. The offered configuration and included items must be explicitly confirmed.
