Product Description:

The CDB01.1C-SE-ENS-EN2-NNN-EN1-S1-S-NN-FW is a compact control section engineered by Bosch Rexroth Indramat for use in the CDB Control Units series. This board functions as the command and feedback hub of an IndraDrive modular servo system, translating fieldbus signals and encoder data into precise torque and speed directives sent to the attached power sections. Within an automated line, it provides the deterministic timing and coordinated axis management required for synchronized motion sequences, material transfer, and process positioning.

To support multi-axis machines, the card manages 2 axes, each serviced through independent encoder interfaces and drive channels. Its idle draw of 9 W minimizes cabinet thermal load while still powering status LEDs, microprocessors, and the SERCOS coupler. For deterministic network traffic, it communicates over SERCOS II, allowing cyclic set-point exchange and real-time diagnostics at up to 16 Mbit/s without additional gateway hardware. During power-up, the control section can absorb an inrush of 6 A, and the surge persists for a maximum of 60 ms; sizing of fuses and supply lines must therefore accommodate this brief but elevated demand to prevent nuisance trips.

For local service tasks, the integrated RS-232 port reaches 115 kBaud and accepts a MiniDIN 8-pin plug on cables up to 15 m, giving direct parameter access when SERCOS is offline. Encoder channel EN1 samples incremental feedback at 4 kHz with a supply of 18.2 Vpp, while channel EN2 sources up to 350 mA and tolerates a 35-ohm load so resolvers or high-current sine-cosine sensors remain correctly biased. A dedicated input marked ENS delivers 12 V for additional evaluation electronics. Functional safety is wired through a D-Sub 9-pin connector, and the inputs conform to 24 V / 3 mA, enabling Safety Technology I/O functions such as STO without external relays.
