Product Description:

The CDB01.1C-S3-ENS-EN2-EN2-S2-S-NN-FW is a control unit from the CDB Control Units series produced by Bosch Rexroth Indramat. Intended for multi-axis drive assemblies, the module provides motion command processing and safety supervision within automated machinery. By integrating encoder supplies, fieldbus communication, and local I/O in one slot card, it acts as the interface between IndraDrive power sections and higher-level controllers on the plant floor. This arrangement lets one card manage position feedback, command exchange, and local signal handling from a central point in the drive assembly.

This card supports 2 drive axes and draws a base load of 9 W from the internal 24 V control bus when idle. Motion commands and parameter data move over SERCOS III, while maintenance and diagnostics can be handled through an RS232 service port. Each analog output steps in 19.5 mV increments, allowing fine process trimming. Two probe inputs capture position markers for registration tasks. The digital outputs can sink or source up to 500 mA, which is suitable for status lamps or similar control loads. Start-up strain on the supply is limited by an inrush draw of 6 A, and the combination of fieldbus communication and local service access supports normal operation without interrupting the control structure.

During energization the inrush window lasts only 60 ms, reducing stress on upstream power supplies. Continuous serial diagnostics reach 115 kBaud for trace capture and status monitoring. The form-C relay carries control logic out to external devices at DC 24 V, 1 A, isolating field wiring from the backplane. Functional safety is handled by the integrated Safe Motion package, enabling certified stop and speed limits without additional hardware. Encoder port 2 delivers 5.0 V at 350 mA for incremental transducers, while the ENS port supplies 11.6 V to multi-turn devices through a separate encoder supply path.
