Product Description:

The CDB01.1C-SE-NNN-NNN-NNN-NNN-L2-S-NN-FW is a double-axis control section manufactured by Bosch Rexroth Indramat within the CDB Control Units series. The module mounts on compatible power sections of the company’s drive controllers to handle signal conditioning, communication, and safety tasks. In automated machinery, it converts fieldbus and analog references into precise pulse-width commands for servo power stages, allowing coordinated motion of multiple axes.

The section supports 2 synchronized axes and communicates with the drive system over the SERCOS II fiber-optic ring through its X20 and X21 connectors. Analog input channel 1 offers a bandwidth of 1.4 kHz, so velocity or torque references with frequencies below this limit pass without attenuation. The same channel presents an input impedance of 160 kΩ, which minimizes loading on upstream signal sources. For feedback to external controllers, the board provides a differential analog output with a step size of 19.5 mV/inc. Loads down to 5 kΩ are supported without loss of linearity, and a single RS-232 maintenance port allows point-to-point monitoring and parameter access for one node.

Each of the eight digital outputs can source up to 500 mA, while the total available per group is 1 A. Inductive actuators connected to these points may return energy up to 400 mJ, and the onboard suppression circuits dissipate this without additional clamps. This output capability supports direct switching of small actuators and status devices from the control section. The integrated safety chain provides the certified Safe Torque Off function through a D-Sub 9-pin female interface, enabling immediate drive disablement without power removal. When service access is required, the serial channel operates at rates up to 115 kBaud, allowing parameter retrieval and diagnostics with minimal cycle interruption. The unit is suitable for packaging lines, electronic assembly cells, and similar multi-axis equipment.
