Product Description:

The CMP70.1-SP-505-FN-K001-FW is a compact control unit produced by Bosch Rexroth Indramat for the CMP Control Units series. Installed in a machine control rack, the card manages axis coordination, collects diagnostic data, and communicates with motion drives to keep production equipment synchronized. It forms the local intelligence between field sensors and higher-level PLCs, enabling deterministic response times required for high-speed assembly, packaging, and material-handling systems. Its rack-based format also supports centralized processing for coordinated machine functions.

It runs on an AMD Sempron, 1 GHz processor, giving deterministic 32-bit computation for interpolation tasks. Working memory is provided by 256 MB SDRAM, allowing the embedded operating system and user application to handle large parameter tables without paging delays. Battery-backed 16 MB SRAM retains configuration data during power cycling. During operation, the board draws only 21 W from the backplane, which helps limit cabinet heat load, while the logic rails are supplied through a regulated backplane line at 5 V DC. This memory arrangement helps the unit start quickly after a power cycle and retain stored calibration data when main power is removed.

Signal exchange with the host rack is handled through a Universal PCI connector that supports both 32-bit and 64-bit transfers. Electrical compatibility with different host backplanes is supported by the dual-voltage PCI arrangement of 5 V / 3.3 V, so jumper selection is not required. The board can source peripheral loads up to 5 A through its auxiliary header, and its ready relay is rated for 60 V / 1 A so status lines can drive external control circuits. The electronic assembly is qualified under climate class 3K3, so it remains functional in control cabinets up to 55 °C and 95% non-condensing humidity typical of factory environments. This interface arrangement also helps the board fit into mixed-generation automation racks that use different PCI backplane standards.
