Rexroth CDB02.1B-ET-EC-EC-EC-L3-L3-EC-NN-FW Dual-Axis CDB Control Section R911340351

The CDB02.1B-ET-EC-EC-EC-L3-L3-EC-NN-FW, material reference R911340351, is listed for Rexroth IndraDrive dual-axis control-section sourcing and maintenance of installed machinery. Preserve the full designation when requesting a spare part. The material reference must be compared with the actual unit nameplate and the applicable catalog before quotation.

Product identification

Two-axis configuration matching

CDB is a double-axis control section. This CDB02.1B configuration belongs to the second-generation BASIC extended-scope family. It must not be described as a single-axis CSB or CSH section. The encoder codes are EC / EC; additional option fields are EC / EC; safety codes are L3 / L3. These separate fields are retained to support exact identification. Similar family names, connector counts or enclosures do not establish interchangeable operation.

The communication designation is ET, Multi-Ethernet. Confirm the installed network, firmware protocol support, encoder requirements and wiring for both controlled axes. Do not infer motor suitability or replacement compatibility from a partial model. A power section, motor, cables and other system components require their own identification and quotation.

Firmware, panel and safety

FW: standard control panel designation; firmware ordered separately. The designation does not assure that a specific firmware release, license, memory card or machine project is included. Record the original firmware type and version, parameter backups and panel requirements. Preserve AW and FW suffixes exactly rather than merging the listings. Panel and accessories actually supplied must be stated in the quotation.

Safety option codes must be reviewed with the exact hardware, firmware and machine documentation. Both axes and the machine safety design require assessment by the responsible technician. No safety performance level or machine approval is promised by this product page.

Replacement enquiry checklist

Send clear photographs of the original full type plate, R911 number, serial number and hardware index. Include the connected power-section designation, firmware identification, installed communication network, motor feedback arrangement for each axis and any required plugs, covers, control panel or removable media. State quantity, destination, acceptable condition and required arrival date.

A proposed alternative must be assessed by its complete designation and documented differences. Encoder evaluation, encoder emulation, analog or digital expansion and safety fields must not be treated as equivalent options. The actual unit must be checked against the original machine configuration before procurement and commissioning.

Condition and spare-part sourcing

This page supports genuine original spare-part enquiries for installed systems, including legacy installations. It does not assert that every configuration has been discontinued. Specify acceptable unused surplus or used condition. Availability, condition, completeness and any inspection records are confirmed for the actual offered unit. No fixed stock, test scope, warranty, manufacturer authorization or guaranteed compatibility is implied.

Budget reference

The displayed USD 1927.90 per piece is a related-model estimate, calculated at 65% of an observed eBay asking price of USD 2966.00 for CDB02.1B-ET-EC-EC-NN-NN-NN-NN-NN-FW. The reference has different communication, feedback, expansion and/or safety options. This is not an exact-model market quotation or a statement of interchangeability. The reference seller’s stock, testing, warranty and lead-time statements are not transferred to this listing. Final quotation depends on the actual unit.

Ordering and delivery

Minimum order quantity is 1 piece. The supply target is 10 pieces per month, subject to actual availability. Confirmed in-stock units normally dispatch within one week; non-stock sourcing and lead time are agreed separately. Payment terms, protective export packaging, freight and included items are confirmed with quotation.

The reused family image is for identification enquiries. Connectors, fitted options, labels and actual appearance may differ. Request current unit photographs before accepting a sourcing proposal.
