Product Description:

Bosch Rexroth Indramat's CDB01.1C-ET-EN1-EN1-EN2-EN2-S2-S-NN-FW is a modular control board from the CDB Control Units series, intended for installation inside IndraDrive power sections. The board forms the command layer that coordinates motor feedback, fieldbus traffic, and safety signals so a drive can execute position, velocity, and torque loops in industrial automation cells. By combining Ethernet-based networks with encoder handling and safe-motion logic, the unit lets machine builders integrate synchronous or asynchronous axes into packaging lines, material-handling systems, and multi-axis machining platforms. It is installed within the drive rather than used as a stand-alone controller.

The analog section provides a reference channel rated at 5 V / 1 mA, giving external hardware a low-power voltage source for transducer feedback or test points. For secondary position feedback, the board carries an auxiliary encoder interface that accepts 2 × EN2 (EnDat2.1/1 Vpp/5 V TTL) channels; each channel is supplied by a dedicated 5.0 V source that delivers 350 mA. Overall base consumption is limited to 9 W, so thermal load inside the drive cabinet remains modest. Network traffic is handled through the multi-protocol ET Multi-Ethernet controller, allowing real-time exchange over EtherNet/IP, EtherCAT, or PROFINET without add-on modules. The typical inrush current peaks at 6 A during startup, after which the steady draw stabilizes.

Data wiring uses a shielded CAT5e, ITP patch lead that mates with an RJ-45, 8-pin receptacle positioned on the front edge of the card for quick access. The I/O rail can source up to 1.1 A maximum for sensors or relay coils, and the digital capture circuit records command pulses as narrow as 60 ms without loss. Primary feedback is accepted through the motor encoder header that supports two EN1 formats used by MHD or MKD motors. Functional safety is handled by the S2 Safe Motion core through a 9-pin female D-Sub connector, enabling STO and SS1 functions without external relays. The front-access connector layout simplifies cable routing in tightly packed drive assemblies.
