Product Description:

The CMP40.1-SP-304-FN-K001-FW is a compact motion and logic controller engineered by Bosch Rexroth Indramat for the CMP Control Units series. Installed in cabinet-level automation stacks, it coordinates drives, spindles, and peripheral I/O so a machine tool or handling system can execute time-critical paths under one deterministic master. By supplying trajectory calculations, fieldbus routing, and readiness signaling, the unit bridges the supervisory PLC layer with the real-time requirements of servo amplifiers and sensor networks. It is typically paired with Rexroth SERCOS drives in packaging, printing, and light machining cells.

At its core, a Celeron 650 MHz processor works with 64 MB of SDRAM to handle program code, axis interpolation, and diagnostic tasks. The firmware completes each function block in 4 ms, maintaining consistent update times for position loops and logical events. For plant networking, the controller integrates an RJ-45 port operating at 10/100 MBit/s, enabling parameter download and remote monitoring over standard Ethernet. When legacy wiring is required, motion data can be exchanged on PROFIBUS-DP at 12 Mbaud. Real-time drive communication occurs through a SERCOS interface that refreshes every 4 ms at 16 Mbaud, while climatic classification 3K3 limits use to filtered, non-condensing enclosures.

The unit supervises 8 servo axes, with four of them interpolated per NC channel. Two NC channels and a spindle capacity of two support concurrent machining routines. The unit has a current draw of 5 A, which guides fuse sizing, and the 21 W loss profile often allows passive ventilation. It operates from a 5 V DC ±5% supply, and ripple beyond tolerance can cause spontaneous resets, so a low-impedance rail is recommended. The ready relay rated 60 V / 1 A can be wired in series with drive contactors to provide a hardware acknowledgment before motion release.
