Product Description:

The CDB01.1C-SE-EN1-EN1-NNN-MA1-NN-S-NN-FW is a control unit produced by Bosch Rexroth Indramat within the CDB Control Units series. It mounts into drive controller racks to coordinate multiple servo drives and handle real-time motion commands in automated machinery. By providing centralized processing, I/O aggregation, and encoder evaluation, the unit forms the logic core that links higher-level PLC tasks with the power electronics that energize motors on the plant floor.

This model supervises motion on 2 digital axes, allowing simultaneous interpolation or independent point-to-point moves. Command and diagnostic data travel over the SERCOS II interface, so cycle-synchronous setpoints reach drives with deterministic timing. Internal electronics draw only 9 W at idle, while logic circuits are supplied through a dedicated 24 V DC feed that keeps parameter memory and bus communication alive during main-power drops. On initial energization, the module can absorb a peak of 6 A for 60 ms; this inrush profile guides sizing of cabinet fusing and auxiliary supplies. Four combined I/O channels accept fast machine signals, switching to logic low below 5 V and to logic high above 15 V, so standard sensor outputs can be wired directly without level shifters.

For analog feedback or process values, the extension card offers two input and two output channels with a resolution of 12 bits across a symmetrical ±10 V span, enabling torque, tension, or pressure loops to be closed inside the drive system. Each digital output can source up to 500 mA, and the grouped port is limited to 1000 mA to protect the board traces. Two EN1 encoder sockets are provided for MHD or MKD motors, giving the controller direct access to position data required for tight velocity and position regulation. These resources let the device concentrate axis control, field I/O, and feedback processing in a single compact module.
