Product Description:

The CML45.1-3P-504-NA-NNNN-NW is a control main unit in the CML IndraControl Hardware series produced by Bosch Rexroth Indramat. It serves as the central processor for machine automation, executing user programs, handling motion sequences, and synchronizing drives, I/O, and HMI stations through its built-in communication channels. This allows one controller to coordinate several machine functions from a single location inside the control cabinet. The enclosure format also supports compact automation layouts where control, communication, and motion tasks must be combined in limited panel space.

An AMD LX800 processor operating at 500 MHz provides the computational core for the controller. The module has 256 MB of DRAM as its main dynamic memory, while an additional 8 MB of SRAM is available for fast deterministic data handling. The unit has no configured NVRAM, so retentive variables must be stored externally or written periodically to flash media. This memory arrangement supports control programs that need quick access to runtime data during cyclic operation. It also keeps the hardware description clear without introducing extra feature options that are not installed on this controller.

Thermal regulation relies on passive airflow because the hardware is delivered without a fan. Its electronics are housed in an inline casing that permits side-by-side mounting on DIN rails and helps conserve cabinet width. Field communication is handled through a dedicated PROFIBUS interface, giving the controller deterministic access to decentralized sensors, actuators, and frequency converters. Hardware release 45 identifies this unit within the broader CML platform. That release information helps match the controller with compatible expansion modules and supports consistent integration within the same hardware generation.
