Product Description:
The CDB01.1C-PB-ENS-ENS-NNN-MA1-S2-S-NN-FW control section belongs to the CDB Control Units series from Bosch Rexroth Indramat. The module serves as the central command layer for compact drive packages, generating setpoints, monitoring feedback, and coordinating motion tasks in industrial automation systems. Designed for cabinet installation, it interfaces with power modules to regulate synchronous or induction motors used on conveyor, packaging, or material-handling equipment. Centralized control processing also helps the connected power section respond quickly to command changes during coordinated motion.
Internally, the unit supervises 2 axes, so a single board can manage a dual-drive arrangement without additional hardware. For fieldbus integration, it offers PROFIBUS communication through a dedicated port presented on a D-Sub 9-pin female connector and supports data rates up to 12 MBaud; deterministic telegram exchange lets higher-level PLCs deliver position and torque commands in real time. An additional S2 service port isolates parameter loading and diagnostics from the main bus, so local access does not interfere with network communication. Integrated safety technology rated as Safe Motion enables hardware-based monitoring of velocity and position, helping support stop and guard functions without external relays.
Both feedback channels are implemented as ENS encoder interfaces, and each sensor pair is wired to a D-Sub 15-pin female socket for quick shielded-cable termination. The onboard MA1 analog section provides ±10 V input and output ranges, with two analog inputs and two analog outputs that are each converted at 12 bits of resolution for velocity trim, load-cell signals, or valve commands. This mix of encoder and analog connectivity allows the control section to process motion feedback and external process signals without separate interface cards. A standard RS-232 serial interface supplies point-to-point access for setup or diagnostics when a fieldbus is not available, and its opto-isolated design helps protect connected devices from drive-side transients.
