Product Description:
The CDB01.1C-ET-ENS-EN2-NNN-MEM-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat for use within the CDB Control Units series. Mounted on a compatible power module, this board manages drive parameters, fieldbus exchanges, and encoder processing for servo axes in automated machinery. By combining processing logic with integrated safety monitoring, it serves as the command layer that links multi-axis motion hardware to higher-level PLC systems in industrial automation. This variant is configured for dual-channel feedback and real-time bus traffic, enabling precise position loops and coordinated movement in packaging, printing, and material-handling lines.
For network integration, the board supports Multi-Ethernet communication, and packets are handled through an embedded switch that presents two 8-pin RJ-45 sockets. The physical layer complies with the 100Base-TX standard, so cables up to 100 m can be used without repeaters. Channel 1 can source up to 500 mA, and its differential TTL input is rated for toggle rates up to 400 kHz. That channel accepts sensors that use IndraDyn / Hiperface / 1 Vss / TTL. During power-up, the card draws an inrush current of 6 A for a pulse width of 60 ms before settling to normal levels. When simulated feedback is required, the onboard emulator transmits through a D-Sub 15-pin connector at programmable frequencies.
The second feedback slot supplies 350 mA to digital sensors and is factory set for the protocol combination EnDat 2.1 / 1 Vss / TTL. When virtual feedback is selected, the emulator can produce square-wave pairs up to 1 MHz, allowing high-speed test sequences without a mechanical axis. Functional safety is implemented through Safe Motion (SIL2 / Cat. 3 PL d), which supervises velocity, position, and stop functions through a dedicated D-Sub 9-pin female connector that links to external safety relays. These functions support synchronized multi-axis machines and allow separate safety circuits to monitor motion states independently of the main control channel.
