Product Description:

Bosch Rexroth Indramat’s CDB01.1C-SE-EN1-EN1-NNN-MEM-S1-S-NN-FW is a plug-in control card within the CDB Control Units series. The board attaches to IndraDrive power sections and coordinates motion commands, feedback processing, and safety signals in industrial automation lines. By handling network communication and local I/O, the module serves as the logical interface between higher-level PLCs and the servo inverters that actuate axes on packaging, printing, and material-handling equipment. The card also manages local signal exchange so the connected drive can respond quickly to machine events without separate interface hardware.

The card draws a base power of 9 W, a low constant demand that simplifies cabinet thermal planning. Command traffic travels over Sercos II, so deterministic telegrams synchronize drive cycles within sub-millisecond windows. The onboard logic supplies the digital I/O rail with 1.1 A, allowing direct power for sensors that require moderate current without external supplies. Position transducers tie into the EN1 sockets, and each safety channel presents an input resistance of 10 kΩ. Its excitation rail can deliver 250 mA at 8 V to optical encoders. Incremental and SSI formats are produced by the encoder-emulation block, so legacy controllers can still receive synthetic quadrature or serial position data. During power-up, the module tolerates an inrush of 6 A, which helps prevent unnecessary trips in upstream protective devices.

Start-up energy surges last no longer than 60 ms, limiting stress on DC-link capacitors. The MEM high-speed capture channel supports cable runs up to 40 m and transmits marker pulses at rates up to 1 MHz with a source capability of 20 mA, enabling remote probes or spindle reference switches to be wired without signal boosters. For maintenance tasks, the RS-232 port exchanges diagnostics at 115 kBaud with service tools. The S1 block sources 0.5 A through its safety I/O contacts, allowing the board to energize external relays while conforming to the S1 I/O safety protocol.
