Product Description:
The CDB01.1C-S3-EN2-EN2-NNN-MEM-S2-S-NN-FW is a control card manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed inside an IndraDrive power section, the card supervises axis currents, interfaces with feedback devices, and coordinates higher-level commands from PLCs or industrial PCs. By combining network communication, analog processing, and onboard safety, it provides centralized motion control for conveyors, packaging machines, assembly cells, and similar automated equipment.
Its primary network layer is SERCOS III, which runs deterministically over the 100Base-TX physical medium and guarantees sub-millisecond synchronization between drives. Two differential analog inputs exhibit an impedance of 160 kΩ, preventing loading of position sensors, and their companion outputs deliver 19.5 mV per increment for proportional valve control. Four digital outputs can source up to 500 mA, and the board itself draws only 9 W of base power from the supply rail. For closed-loop positioning, the module includes 2 × EnDat 2.1 / 1 Vpp / 5 V TTL connectors plus SSI and incremental emulation, so a wide range of linear or rotary encoders can be used. Parameter access and diagnostics are available through the RJ-45, 8-pin engineering port, while a 60 ms maximum inrush pulse is tolerated at startup.
The MEM axis extension port streams reference pulses at 1 MHz, supports cable lengths up to 40 m, and withstands a typical inrush current of 6 A without tripping upstream protection. For external interlocking, a relay contact rated at DC 24 V, 1 A is provided, and the integrated safety layer meets the Safe Motion profile so motion can be inhibited without removing power. Additional connectivity is offered through the serial RS232 link for service access, parameter exchange, and local communication with compatible setup tools.
