Product Description:

The CDB01.1C-S3-EN2-EN2-EN2-NNN-NN-S-NN-FW is a compact control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed in Rexroth drive assemblies, this module coordinates power stages and feedback channels so multi-axis motors can be commanded from higher-level PLCs. Acting as the central logic layer, the unit conditions encoder signals, processes motion profiles, and distributes command data across the drive network for precise regulation in packaging, printing, material-handling, and similar automation lines. It is intended for drive configurations that combine motion control, feedback processing, and networked command exchange on one compact section.

At the hardware level, the board supervises two motion channels. The 2 axis capacity lets a single unit govern paired servomotors without an additional controller. Real-time communication is handled by SERCOS III over the onboard 100Base-TX link through the S3 Ethernet jack, so cyclic setpoints and status data move between the control layer and the drives with low latency. Internal consumption is limited to 9 W, reducing panel heat and easing supply sizing. A start-up 6 A inrush current rating sets the minimum fuse size and precharge behavior during power application.

Signal conditioning resources complement the communication layer. Each channel can source field devices through a 500 mA digital output driver and accept high-speed counters fed by the EN2 inputs supported with a stabilized 5.0 V supply rail. The unit provides three encoder interfaces, enabling simultaneous position feedback for both axes plus an auxiliary probe. Output interlocking or alarm forwarding can be handled by the onboard relay that carries 24 V DC, 1 A across its contact set. This arrangement also allows encoders, auxiliary probes, and relay-based status signals to be managed from one location in the drive assembly.
