Product Description:

The Bosch Rexroth Indramat CDB01.1C-SE-ENS-ENS-EN2-MEM-S1-S-NN-FW control unit belongs to the CDB Control Units series. It plugs into an IndraDrive drive stack and supplies the signal conditioning, communication, and logic needed for closed-loop motion tasks. Within an automation cell, the module converts sensor feedback and host commands into real-time torque and speed references for servo axes, coordinating conveyors, pick-and-place stations, and other electromechanical loads.

The analog section is designed for precise sensor scaling. An input impedance of 180 kΩ prevents loading of potentiometers or strain gauges, and each conversion step is quantized at 5.5 mV/inc to preserve fine signal changes. When the board drives external actuators, its digital-to-analog converter issues steps of 19.5 mV/inc from a full-scale reference of 5 V. All axis and parameter data are exchanged over SERCOS II, giving deterministic timing through fiber rings, while a separate RS-232 port can be routed up to 15 m for service access. The nine-pin S1 connector presents discrete I/O, and a form-C relay channel is rated at 1 A for safety loops.

For position latching and encoder extension, the board offers two EnDat 2.2 channels. When the sense conductors are used, incremental feedback can travel up to 75 m; without them, the reach is limited to 50 m, and both links share a dedicated encoder supply. The auxiliary ENS channel feeds external sensors with a stabilized 12 V line, reducing the need for separate power supplies in the cabinet. High-speed event capture relies on the MEM interface, which streams data over 40 m of cable, sources 20 mA, and toggles at a maximum of 1 MHz. A hardware probe strobe with a width of 4 µs timestamps mechanical positions for tasks such as on-the-fly printing and tool measurement.
