Product Description:

The CMP40.2-SP-304-FN-K001-FW is a motion and numerical control unit developed by Bosch Rexroth Indramat within the CMP Control Units series. Mounted on a PCI backplane, the board combines axis management, fieldbus gateways, and real-time trajectory calculation to coordinate servo and spindle drives in automated machinery. By providing deterministic task scheduling, it links PLC logic with SERCOS, PROFIBUS, and standard Ethernet channels, allowing machine builders to synchronize multiple axes and peripheral devices from a single compact module. The controller also handles up to two NC channels and two independent spindles, permitting split machining zones without extra hardware.

This control unit can supervise up to 8 servo axes while maintaining a minimum block sequence update of 4 ms, so complex machining paths are recalculated every four milliseconds. A Celeron 650 MHz CPU executes the interpolation algorithms, and its on-board 64 MB of SDRAM stores NC programs and buffering data required for look-ahead processing. Even with the processor, memory, and communication interfaces active, electrical demand stays at only 21 W, which eases cabinet thermal design and power budgeting for auxiliary electronics.

Input power is delivered through the backplane at 5 V DC with a maximum draw of 5 A, so designers can pair the card with standard ATX or industrial supplies without dedicated converters. Axis drives connect over SERCOS rings that transmit telegrams at 16 Mbaud, while factory networks can exchange diagnostic data through the PROFIBUS-DP port running at 12 Mbaud. An 8-pin RJ45 socket provides Ethernet connectivity up to 100 m for HMI or supervisory hosts, and the dual-height PCI form factor supports both 5 V and 3.3 V signal levels to suit legacy or modern controller racks.
