Product Description:

Bosch Rexroth Indramat manufactures the CDB01.1C-S3-ENS-ENS-EN2-MA1-NN-S-NN-FW, a plug-in control card in the CDB Control Units series. Installed in IndraDrive amplifier stacks, it coordinates command processing, encoder evaluation, and discrete field wiring for industrial motion axes. The board translates higher-level PLC instructions into precise drive signals, enabling synchronized positioning and speed control across packaging, material-handling, and assembly machinery. Its layout allows control functions, feedback handling, and local signal exchange to remain on a single compact module inside the drive system.

The electronics have a base dissipation of 9 W, so cabinet ventilation demands stay moderate during normal operation. Logic power is supplied on the EN2 rail at 5.0 V, and the card draws up to 350 mA from that source; this line feeds DSP cores and memory used for motion tasks. Auxiliary circuitry is supported by an ENS rail rated at 11.6 V, which carries peripheral loads such as status LEDs and small relays. Startup protection is handled by an internal limiter that allows an inrush of 6 A without damaging upstream breakers. Each digital output group can source 1 A in total, while individual points are restricted to 500 mA to help prevent conductor overheating during fault conditions.

After power is applied, the inrush event is confined to a duration of 60 ms, which helps limit stress on filter capacitors and related supply components. Driver transistors absorb up to 400 mJ of inductive load energy, allowing direct actuation of pneumatic valves or clutches without separate suppression hardware in many installations. For analog precision, the integrated converter produces an output granularity of 19.5 mV/inc, and the MA1 input channel handles feedback signals with a bandwidth of 1 kHz. The card also supports accurate timing for probe signals and stable interfacing with connected field devices, which helps the drive respond cleanly to machine events and feedback changes.
