Product Description:

The CDB01.1C-PB-EN1-EN1-NNN-MEM-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CDB Control Units series. Mounted on a compatible power module, it performs all real-time regulation tasks for connected servo hardware, translating velocity and position commands from a PLC into precise current patterns for the inverter stage. By combining fieldbus communication and feedback processing in one compact board, the unit delivers the coordination layer required for multi-axis motion in packaging, printing, and general factory automation cells.

Internally, the section supervises 2 axes, each supplied with a control voltage of 24 V DC drawn from the cabinet’s auxiliary supply. Command exchange with the host controller occurs over PROFIBUS, while local machine states are read through 18 digital inputs and proportional devices are driven by two analog outputs. Two HSF/RSF encoder ports close the position loop. The current loop updates every 125 µs, followed by speed processing at 250 µs and position evaluation at 500 µs, creating a deterministic cascade that preserves contour accuracy during rapid load changes. A standard front control panel gives direct parameter access, and this version is delivered without a built-in safety option.

Physical integration is simplified by the housing profile; the unit measures 49.5 mm in width, 322.6 mm in height, and 103 mm in depth, allowing two control sections to share a 100 mm rail space. Option slot 4 carries Encoder Emulation, which supplies synthetic incremental feedback signals for legacy motion hardware, while option slot 3 is left vacant for user-selected modules. Cabinet airflow remains unobstructed by the slim outline, and molded guide rails align with standard Rexroth power sections for straightforward slide-in assembly.
