Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-MA1-L2-S-NN-FW is a plug-in control unit from Bosch Rexroth Indramat that belongs to the CDB Control Units series. Installed in IndraDrive power sections, it executes motion commands, manages feedback, and handles safety for servo axes in industrial automation cells. By processing encoder signals and fieldbus traffic in real time, the module coordinates torque, velocity, and position loops for connected drives without external PCs.

This model supervises 2 motion channels and exchanges process data through a Multi-Ethernet interface, allowing simultaneous access by SERCOS III, EtherNet/IP, and PROFINET controllers. Each base analog channel can source up to 1 mA and converts its command word with 8-bit granularity, which is suitable for low-power actuators such as proportional valves. Discrete inputs treat anything above 15 V as logic “1,” while the transistor outputs can sink or source up to 500 mA for contactors or pilot lamps. Communication diagnostics are available through the RS232 maintenance port, and the link can stream parameter blocks at 115 kBaud. The integrated Safe Torque Off function removes drive enable lines to meet category-oriented shutdown requirements without adding external relays.

The ENS feedback socket provides an encoder supply of 11.6 VDC, ensuring stable sensor excitation even when bus power fluctuates. For higher-precision analog tasks, the MA1 input presents 1000 kΩ of impedance and resolves signals with 12-bit depth, while its output path can deliver 10 mA into a 1 kΩ load for reference generation. Control logic may also energize field devices through the onboard relay, rated at 24 VDC, 1 A, eliminating the need for separate interposing hardware. These resources let the unit complete measurement, command, and safety chains inside compact multi-axis cabinets.
