Product Description:
The CDB01.1C-SE-EN1-EN1-ENS-NNN-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat for its modular CDB Control Units series. Intended for multi-axis drives, this unit serves as the central controller that processes feedback, generates analog command values, and links the drive pack to higher-level automation through fieldbus. In industrial motion systems, it governs torque, velocity, and position loops so that synchronous and induction motors follow programmed trajectories.
Inside the controller, two analog command channels can each source up to 1 mA or swing to 5 V so that downstream power stages receive finely scaled reference signals. The unit supports 2 axes, letting a single card coordinate a pair of drives without an external motion card. Synchronous communication with the master PLC occurs over the SERCOS II fiber-optic ring, delivering deterministic cycle times and diagnostic telegrams. Encoder Slot 1 and Slot 2 accept Resolver/HSF feedback, while Slot 3 is reserved for a standard incremental or absolute encoder evaluation board. For the high-speed feedback option, the HSF interface is powered from an isolated rail of 8 VDC, which helps prevent ground loops between resolver electronics and the drive chassis.
The first encoder channel excites its resolver windings at 4 kHz, and the transducer receives a carrier amplitude of 18.2 Vpp, which supports a high signal-to-noise ratio during rapid servo moves. Auxiliary electronics on the ENS line draw up to 500 mA from a regulated 11.6 VDC source, so no separate supply is required for option cards. Safe Motion monitoring and the safe I/O block are energized by 24 VDC and can switch up to 1.6 A to field devices such as contactors or light curtains. A bidirectional RS232 service port is provided for setup and non-real-time diagnostics.
