Product Description:

The CDB02.1B-ET-EC-EC-NN-SB-SB-NN-NN-FW belongs to the CDB Control Units series manufactured by Bosch Rexroth Indramat. This unit forms the command layer in drive systems, processing field feedback and issuing motion directives to the attached power stage. By combining network communication, encoder processing, and safety circuitry in a single slot card, it supports coordinated multi-axis operation in factory automation, packaging lines, and material-handling cells.

During operation, the controller draws a base load of 23 W from a regulated DC 24 V control supply, so cabinet power budgeting remains predictable. It provides 14 digital inputs, and the first eight lines can be reassigned as outputs when flexible machine layouts are needed. Two ±10 V analog input channels accept speed or torque references, while a matching pair of analog outputs returns processed values for monitoring devices. Multi-Ethernet communication uses a 100Base-TX connection through an 8-pin RJ-45 jack, enabling real-time data exchange with EtherNet/IP, PROFINET, or EtherCAT hosts. Four probe inputs capture edge-aligned position events to microsecond resolution, and twin encoder ports support high-speed servo loops.

The controller mates electrically and mechanically with the HMD01 power section, creating an integrated axis module without additional wiring. It also provides 8 freely mappable software channels for status or handshake tasks. Feedback is handled through dual Multi-Encoder Interface ports, allowing simultaneous evaluation of incremental and absolute encoder signals. The safety link uses dual Safe Motion Bus channels, which carry STO and SS1 commands within safety-related control architectures. Four optional slots accommodate fieldbus, memory, or additional I/O cards, and dual 4-channel probe and 4-channel optional modules keep wiring density balanced across the backplane.
