Product Description:

The CDB01.1C-PB-ENS-ENS-NNN-MEM-L2-S-NN-FW is a drive controller sub-module manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed inside an IndraDrive power section, the board acts as the logic core that links motion commands, fieldbus traffic, and encoder feedback so that multi-axis machinery can be synchronized and monitored within an industrial automation cell. It processes internal control tasks for the drive section and supports coordinated machine operation without requiring a separate standalone control board.

This model supervises 2 axes of motion, assigning one processing channel to each drive. Network communication is handled through PROFIBUS, enabling real-time parameter exchange with PLCs, and the bus enters the board on a D-Sub interface that follows the protocol's pinout. For reference output tasks, the unit provides a 5 V / 1 mA analog signal, while incoming control contacts load the input stages at 24 V / 3 mA. Incremental or absolute encoder data is accepted on the shared socket that supports IndraDyn/Hiperface/1 Vpp/5 V TTL formats, allowing mixed feedback types without additional converters. Operators adjust parameters from a standard front-mounted panel, and a separate RS-232 serial link offers point-to-point diagnostics when the fieldbus is not available.

No auxiliary power source is needed because the memory section does not require an external supply, so all RAM and flash areas are sustained by the drive's internal rails. Data buffering and trigger functions are protected by a galvanically isolated mezzanine that clocks events up to 1 MHz. Application files load through a MultiMediaCard slot, and status relays switch loads up to DC 24 V, 1 A for alarm lamps or contactors. Safety wiring shares a nine-pin female connector with the STO circuit, and the board relies on Safe Torque Off so motor torque is removed immediately when an emergency chain opens.
