Product Description:

Bosch Rexroth Indramat produces the CDB01.1C-ET-ENS-ENS-EN2-EN2-L2-S-NN-FW control unit within the CDB Control Units series. The CDB01.1C-ET-ENS-ENS-EN2-EN2-L2-S-NN-FW is a modular drive controller interface that combines communication, safety, and feedback processing for industrial automation in demanding motion applications. Mounted in a cabinet, it coordinates servo power sections and field networks to control multiple axes. Integrated encoder inputs and an Ethernet link connect directly to PLCs, eliminating external gateways and reducing wiring inside robotic cells. This arrangement lets one module handle feedback exchange, network communication, and axis-related control functions without relying on several separate interface cards.

Physical dimensions keep wiring space predictable: the housing is 49.5 mm wide, 103 mm deep, and 322.6 mm high, allowing side-by-side stacking inside standard 300 mm cabinets. A standard control panel is installed on the front for local parameter entry. Front access supports status checks and menu navigation when the unit is mounted beside other drive components in a dense control cabinet. Two X4 ports accept IndraDyn / HIPERFACE / 1 Vpp / TTL signals, while two X8 ports handle EnDat 2.1 in identical line-driver formats, so both legacy and high-resolution feedback are supported. Network traffic reaches the controller through an RJ-45, 8-pin connector that follows the 100Base-TX layer, enabling cyclic exchanges with SERCOS III or EtherNet/IP.

The safety layer uses Safe Torque Off, removing drive power without interrupting communication and meeting SIL3 and Category 3 PL e safety requirements. A Multi-Ethernet master supports Profinet, EtherNet/IP, EtherCAT, or SERCOS with no hardware change, so one module can be used across different automation platforms. For legacy tools, a serial channel reaches 115 kBaud, giving command-line access when Ethernet is unavailable. Direct serial access is useful for diagnostics and basic setup when the network is not active. This mix of communication and feedback options supports machines that use different encoder families and Ethernet protocols on the same platform.
