Rexroth CSB02.5B-ET-EC-CN-L3-NN-NN-NW CSB Control Section R911380777

Rexroth CSB02.5B-ET-EC-CN-L3-NN-NN-NW CSB Control Section R911380777

The CSB02.5B-ET-EC-CN-L3-NN-NN-NW, material reference R911380777, 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

CSB02.5B is recorded as extended interface scope. The requested master communication is ET: Multi-Ethernet. Interface 1 is EC: multi-encoder interface, while interface 2 is CN: CANopen. These fields are retained separately because changing an encoder or communication option can change the machine integration requirements. The .5 design is identified in the manufacturer type-code guide for Hxx05 power sections. Preserve that design index; do not treat a .1 section as an automatic substitute.

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 L3 field identifies a Safe Torque Off (STO) option in the manufacturer type-code guide. The code identifies an option, but it does not establish that a sourced unit is correctly configured or validated for your machine. Confirm the actual module, wiring, firmware, parameter settings and required evidence for the intended installation.

The final NW suffix explicitly identifies a version without a control panel and without firmware. Do not quote this as a ready-to-run FW assembly. Specify the separately required panel and firmware arrangement, if any, and identify the original power section and machine configuration. Any additional components must be listed individually 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 1852.50 per piece is a similar-model budget estimate, calculated at 65% of an observed asking price of USD 2850.00 for CSB02.1B-ET-EC-EC-NN-NN-NN-FW. The reference is a different configuration, including a different design generation and is used for an initial budget only. It does not establish an exact-model market price or technical interchangeability. The reference seller’s stock, condition, testing, warranty and delivery promises are not transferred to this listing.

Request CSB02.5B-ET-EC-CN-L3-NN-NN-NW, catalog reference R911380777, 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?
NW means without firmware and without a control panel. The offered configuration and included items must be explicitly confirmed.
