Product Description:

The CDB01.1C-S3-EN1-EN1-NNN-MA1-L1-S-NN-FW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. This plug-in controller mounts on a modular drive platform and handles local signal conditioning, feedback processing, and network communication for servo axes. By combining motion control logic with field connectivity, the unit coordinates motor drives, encoders, and higher-level PLCs within automated assembly lines, packaging systems, and material-handling workcells.

The board offers two analog input channels that are configured as two differential inputs, allowing noise-immune sensor measurements over twisted-pair wiring. Each input accepts a bipolar span of ±10 V and is digitized at 12 bits of resolution, so position or torque references can be captured with fine granularity. Command generation is mirrored on the output side with two ±10 V drivers that use the same conversion depth, enabling symmetrical signal flow between external transducers and drive amplifiers. During idle operation, the electronics draw a base load of 9 W, which is useful for cabinet thermal calculations. Rotor feedback is connected through a 15-pin D-Sub female connector, and two selectable HSF or resolver interfaces on the board manage incremental or absolute encoder formats without additional adapters.

Physical integration is aided by a footprint of 322.6 × 49.5 × 103 mm, so multiple units can be arranged in narrow enclosures while still meeting clearance requirements for airflow. For plant networking, it supports 10/100 Base-T Ethernet on dual RJ45 ports, and deterministic drive coordination is handled through the real-time protocol SERCOS III. A built-in starting lockout satisfies functional safety interlock needs by inhibiting drive enable until validation is complete, while the inrush phase is limited to 6 A to help avoid nuisance circuit breaker trips when the supply bus is energized.
