Product Description:
The CDB01.1C-SE-EN1-EN1-NNN-MA1-S1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Serving as the command layer inside an IndraDrive modular system, the unit supervises up to two servo axes, distributes feedback signals, and relays data to higher-level automation controllers. By combining real-time communication, analog expansion, and integrated safety channels in a single plug-in assembly, the product streamlines panel layouts and reduces wiring in industrial automation cells. Its role is centered on coordination and signal handling, so the drive can manage motion feedback, command exchange, and safety-related functions from one control section.
Motion and feedback data are exchanged over the SERCOS II optical bus, allowing deterministic synchronization between drives and CNC or PLC hosts. The board handles 2 control axes, and each axis is supported by two incremental or serial encoder channels with 12-bit A/D conversion for precise position capture. Sensor power is provided at 8 V DC, which removes the need for a separate supply in many encoder arrangements. A high-speed trigger input supports signals up to 100 kHz for fast probe tasks. The MA1 analog module adds two differential inputs and two outputs that operate within a ±10 V range, so external velocity or torque commands can be connected directly without extra signal conditioning hardware.
A resolver interface supplies 18.2 Vpp excitation, which supports hybrid feedback arrangements in applications where optical encoder use is less practical. Functional safety is supported through 7 safety inputs, while semiconductor outputs at 24 V / 0.5 A can be used for actuator muting or status indication. An onboard relay provides a switching capacity of 24 V / 1 A for hard contactor control. This combination allows the control unit to support safe stop, guard door, and emergency stop circuits while remaining compact within the drive stack. The separation of motion control functions and safety signaling also helps keep system connections organized inside modular drive cabinets.
