Product Description:

The CDB01.1C-S3-ENS-ENS-NNN-NNN-L2-S-NN-FW is a plug-in control unit produced by Bosch Rexroth Indramat for the CDB Control Units series. It mounts on an IndraDrive power section and supplies motion processing, feedback interpretation, and fieldbus management for connected servo axes. Within an automation line, the card coordinates velocity, position, and torque loops so that packaging machines, gantry loaders, or forming presses can execute time-critical profiles with deterministic control. Its compact format reduces panel space requirements.

The card supports an axis count of 2. Command and diagnostic data reach the controller over the real-time Ethernet protocol SERCOS III, and link lengths can extend to 100 m on a 100Base-TX line without repeaters. For analog position or torque references, the unit provides a differential input that tolerates ±10 V and presents a high input impedance of 160 kOhm, which helps prevent loading of upstream signal sources. It can retransmit scaled process values through a 1 mA analog source and provides a fixed output level of 5 V. Relay terminals rated at 24 V DC and 1 A allow voltage-free switching of external actuators, while the onboard Ethernet jack preserves bandwidth for engineering tasks that run at the same time as cyclic drive traffic.

The unit drives brake solenoids or indicator lamps directly through transistor outputs that can deliver continuous currents up to 0.5 A. Encoder feedback enters on a D-Sub 15 female socket; the board accepts sinusoidal signals at 1 Vpp, complementary square waves at 5 V TTL, and a 12 V DC sensor supply. A probe channel monitors edge events with a timing resolution of 1 µs, which permits precise registration moves synchronized to product flow. When the system requests immediate shutdown, the integrated functional safety feature Safe Torque Off disables gate firing so motor torque falls to zero without relying on mechanical contactors.
