Product Description:
The CMP40.2-SP-304-FN-NNNN-NW control unit is manufactured by Bosch Rexroth Indramat and belongs to the CMP Control Units series. Designed for industrial automation, it functions as the central numerical and logic processor in machines that require synchronized axis control, spindle management, and real-time fieldbus communication. By running onboard control software that calculates trajectories and coordinates drive commands, the device links operator programs to servo amplifiers and I/O, enabling deterministic sequencing across machining centers, packaging lines, and robotic cells.
The unit is driven by a Celeron 650 MHz processor that executes motion and PLC instructions, while a 64 MB SDRAM module buffers user programs, real-time variables, and fieldbus data. A 265 kB L2 cache further shortens memory latency, helping the controller reach a minimum block processing time of 4 ms for contouring commands. Typical operation draws only 21 W from a regulated 5 V DC backplane, and current demand does not exceed 5 A, which simplifies power supply sizing inside the cabinet. The internal synchronization hardware matches the SERCOS interface cycle so that drive telegrams align with block execution and maintain coherent torque and position updates across the motion network.
It can coordinate up to 8 servo axes, with interpolation of four axes per CNC channel, two numerical-control channels, and two independent spindles. This distribution lets a single hardware platform synchronize tool paths and spindle speeds in dual-channel machine centers. Communication bandwidth is sized for these loads: the optical SERCOS ring reaches 16 Mbaud, while the PROFIBUS port supports 12 Mbaud for legacy drives and I/O. Standard Ethernet traffic is handled over 100Base-T cabling, and the copper segment may be extended to a maximum of 100 m without repeaters, enabling remote HMI panels or data collection nodes to link directly to the controller’s integrated switch.
