Product Description:

The CDB01.1C-S3-ENS-ENS-MEM-MA1-NN-S-NN-FW is a compact control section manufactured by Bosch Rexroth Indramat within the CDB Control Units series. Mounted inside an IndraDrive power module, it serves as the central processor that supervises drive behavior, closes servo loops, and links the drive package to plant-wide networks. By evaluating position feedback and generating command values, the unit supports coordinated multi-axis motion in automated assembly stations, conveying systems, and packaging machinery. Its placement inside the power module keeps control and drive functions in one integrated assembly.

This control section manages motion for 2 axes and exchanges cyclic data through the SERCOS III interface, giving deterministic timing between the drive and the PLC. Each axis features standard encoder evaluation channels that accept absolute and incremental feedback while delivering an encoder supply of 11.6 VDC. Internally, the differential inputs are digitized with a resolution of 12 bit, and the built-in encoder emulation can output position pulses at up to 1 MHz. Galvanic isolation separates the emulation drivers from the control logic to help prevent ground loops, and base power consumption is 9 W, leaving room for nearby I/O hardware in the same enclosure.

The option board provides two analog inputs and two analog outputs, and each channel has a ±10 V span for direct analog signal handling. A cold-start inrush current of 6 A can appear for up to 60 ms before the supply settles to its nominal draw. The TTL capture channel records edge sequences up to 400 kHz, supporting high-speed registration marks and other time-sensitive trigger signals. The unit does not include integrated safety technology, so external safety circuits are required.
