Product Description:

The CDB01.1C-ET-EN2-EN2-NNN-MEM-L1-S-NN-FW is a plug-in control unit produced by Bosch Rexroth Indramat as part of the CDB Control Units series. It mounts on a drive base and supplies motion logic, network connectivity, and local diagnostics so that axes can be coordinated inside an automated machine. By combining communication processing, encoder evaluation, and safety interlock functions in one compact module, the device serves as the central command layer for the associated power section. It also keeps encoder handling and network communication on the same module, which simplifies signal routing between the drive base and the machine controller. Its compact form factor allows direct integration into multi-axis controllers without increasing enclosure depth.

During steady operation, the module dissipates only 9 W, which helps keep cabinet temperatures low. Uplink traffic is routed through the Multi-Ethernet interface, and the physical layer uses 100Base-TX through an RJ-45, 8-pin connector. A single-line control panel display supplies direct status readout and parameter entry for local access at the unit. The control unit supports EnDat 2.1, 1 Vpp, and 5 V TTL feedback, and its encoder channels can copy position data on an auxiliary line that switches at up to 1 MHz. For discrete actuation tasks, five digital outputs are available with a continuous load of 500 mA, while the dedicated emulation line is limited to 20 mA.

The encoder-emulation path is Galvanically Isolated from the logic ground, and the integrated supply provides 5.0 V at 350 mA to power external sensors. That isolated path helps preserve signal integrity when emulated feedback is passed to connected control hardware. When line power is applied, the hardware can draw a peak inrush pulse lasting 60 ms, and the typical inrush current is 6 A. A Stop Category 0 starting lockout blocks drive enable until all permissive conditions are met, preventing unintended motion.
