Product Description:

The CDB01.1C-S3-ENS-EN2-EN2-EN2-S2-S-NN-FW is a plug-in control section built by Bosch Rexroth Indramat for the modular CDB Control Units series. Installed on an IndraDrive stack, it supervises two servo axes, routes encoder signals, and exchanges status data with higher-level controllers. Its role in industrial automation is to generate synchronized motion profiles and pass them to the power stage so actuators follow programmed positions and speeds. The board integrates serial real-time communication hardware and local diagnostics, making it suitable for packaging machines, handling robots, and general-purpose machinery.

This unit governs 2 axes and communicates over SERCOS III, a deterministic Ethernet protocol implemented through an RJ-45 8-pin port. Motion data and parameter sets travel at up to 115 kBaud, while status messages appear on the single-line display for local service. Each analog monitoring channel delivers a resolution of 19.5 mV/inc, enabling fine current or sensor scaling. A per-channel digital load of 500 mA can be sourced without exceeding internal drivers, and individual command pulses may stretch to a maximum width of 60 ms so that slow-actuating devices are still detected. The board draws a temporary inrush of 6 A when the drive first powers up, after which current stabilizes under normal operation.

The logic circuitry and sensors run from 9 W delivered by the base board, minimizing cabinet thermal load. Incremental encoder channels labeled EN2 are supported with 5.0 V DC at a continuous 350 mA, while absolute encoder lines tagged ENS receive 11.6 V DC and can draw up to 500 mA for multiturn devices. Integrated diagnostics verify that these rails stay within tolerance so that position feedback remains reliable. For risk-reduced operation, the controller offers the Safe Motion function, allowing speed, position, and stopping limits to be checked in hardware without reliance on the main PLC.
