Bosch Rexroth CML40.2-SP-330-NA-NNNN-NW – High‑performance Motion-logic Controller for Modern Machine Automation

• Motion + PLC on one platform – IndraMotion MLC combines multi-axis control with IEC 61131‑3 logic, reducing controller count and field wiring.

• SERCOS III master – Real-time drive bus for Rexroth IndraDrive, giving tight synchronization and short cycle times for demanding axes.

• Open industrial Ethernet – Dual RJ45 ports typically support service/engineering and plant network access; gateway options for PROFINET, EtherNet/IP, and PROFIBUS are common in this family.

• Scalable performance – The “SP‑330” variant is tuned for mid‑to‑high motion counts, which in many cases is plenty for packaging, converting, and handling systems.

• Diagnostics you can trust – Integrated web diagnostics and clear status LEDs help maintenance teams identify issues quickly, typically without a laptop.

• Rexroth I/O ecosystem – Works with Rexroth S20/Inline remote I/O and safety components, keeping machine architecture consistent.

• North American readiness – The -NA hardware variant aligns with UL/CSA expectations, simplifying site approvals in the US and Canada.

The CML40.2 typically fits machines that need synchronized multi‑axis motion and deterministic timing: packaging lines, cartoners, FFS, palletizers, printing/converting, woodworking, assembly systems, and light machine tools. One thing I appreciate is how easily it scales from a few axes to a couple dozen without changing the overall architecture.

• Reliability – Proven Rexroth hardware with robust EMC design, which in many cases reduces nuisance trips compared to generic IPC+softmotion setups.

• Compatibility – Native with IndraDrive and Rexroth I/O; easy integration to plant networks (PROFINET, EtherNet/IP) through standard options.

• Lifecycle savings – Fewer components to maintain, shorter commissioning time with IndraWorks, and reusable motion function blocks.

• Support ecosystem – Global Rexroth service and documentation; spare parts availability seems to be strong in most regions.

• Cabinet environment – Mount on EN 60715 DIN rail in an IP54 or better cabinet; keep ambient 0…+55 °C with adequate ventilation. Leave clearance above/below for airflow.

• Wiring – Use a stabilized 24 VDC supply with proper grounding. For SERCOS III and Ethernet, Cat5e/Cat6 shielded cables with correct bonding keep jitter low.

• EMC & safety – Bond PE to a low‑impedance ground, segregate power and signal wiring, and route motor/drive cables away from I/O lines.

• Routine care – Back up the application and parameters after changes; check connectors annually; keep ventilation paths free of dust; apply Rexroth firmware updates during planned downtime.

• Spare strategy – Keep one controller and one SERCOS switch/cable set per line; it typically shortens recovery time significantly.

• CE compliant (EMC and Low Voltage directives)

• UL/cUL (UL 508) for North America – aligned with the -NA variant expectations

• RoHS compliant; REACH conform

• Manufacturer’s warranty: 12 months (365 days)

• Rexroth IndraDrive (C/H/M series) with SERCOS III interface for multi‑axis motion

• Rexroth S20 or Inline remote I/O modules for digital/analog expansion

• 24 VDC industrial power supply (with buffer module if required)

• Shielded Cat5e/Cat6 patch leads and SERCOS‑rated Ethernet infrastructure
