Product Description:

Bosch Rexroth Indramat produces the CDB01.1C-SE-ENS-EN2-EN2-NNN-NN-S-NN-FW control section for modular drive assemblies. As a member of the CDB Control Units series, this plug-in card provides central processing and signal conditioning for two drive axes inside an IndraDrive system. Its role in industrial automation is to route command, feedback, and I/O signals between the motion controller and associated power modules through a single backplane connection. Standardized connectors also carry auxiliary voltages to installed interface modules, which helps keep signal and support wiring organized within the drive system.

Two analog outputs are present on the card. Each channel can supply 1 mA or regulate a reference level of 5 V for external command signals. The unit supervises 2 axes, allowing coordinated moves such as master-slave camming in dual-axis applications. Communication with the host controller uses the fiber-optic SERCOS II ring for real-time data exchange. Internal PWM generation reaches a maximum switching frequency of 8 kHz, which helps reduce current ripple in the connected inverters. Additional digital inputs and outputs interface with sensors and limit switches for machine-side control tasks.

Extension connectivity is organized through modular slots. Two EN2 housings are populated, and each one is powered by 5.0 V at 350 mA, while a single ENS module draws 500 mA from an 11.6 V rail. One slot remains unused, leaving space for a later expansion module if the drive layout requires it. The real-time network can exchange telegrams every 1000 µs, which keeps bus traffic aligned with the internal control cycle. For direct actuation of contactors or brakes, an onboard relay contact is rated at 24 VDC, 1 A. Safety functions are not integrated, so emergency-stop and functional-stop circuits must be provided externally.
