Bosch Rexroth PPC-R02.2N-N-NN-P2-NN-FW – Motion/Logic Controller for Multi‑Axis Automation and PROFIBUS Networking

The Rexroth PPC-R02.2N-N-NN-P2-NN-FW is a compact motion/logic controller designed for coordinated multi‑axis applications. From my experience, this PPC-R02 generation is typically used as the central controller in DIAX/IndraDrive systems, acting as a SERCOS master for precise axis synchronization while linking plant I/O and higher‑level PLC/SCADA via PROFIBUS‑DP. The “FW” suffix indicates firmware is supplied/ordered separately, which is common in this Rexroth family and makes licensing flexible for different machine configurations.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• SERCOS master for multi-axis control – Typically used to coordinate multiple servo axes with deterministic timing and fast synchronization.
• Integrated PROFIBUS‑DP (P2) – You might notice the “P2” code; in many cases this denotes a PROFIBUS‑DP interface for remote I/O, HMI, or higher‑level PLC connectivity.
• 24 VDC control power – Common cabinet supply, straightforward to integrate with existing machine control power rails.
• Firmware supplied separately (FW) – Allows you to match the licensed function set to the machine’s needs and avoid paying for unused options.
• Service/diagnostics port – Typically an RS‑232 service interface for commissioning and troubleshooting; status LEDs aid quick diagnostics.
• Cabinet‑mount form factor – Compact controller module, well‑suited for retrofit or like‑for‑like replacements in legacy Rexroth systems.

Technical Specifications

Application Fields

This controller is commonly specified where coordinated motion and reliable fieldbus I/O are needed. Typical use cases include:

• Packaging lines (multi‑axis infeed, sealing, carton handling)
• Printing and converting (register control, web handling)
• Machine tools and metal forming (positioning, auxiliary axes)
• Woodworking and furniture production (gantries, saws, drills)
• Material handling and robotics peripherals (indexers, pick‑and‑place)

A maintenance lead I spoke with recently mentioned that swapping a failing PPC-R02.2N for a like‑for‑like unit brought a discontinued packaging cell back online within a day—no mechanical changes, just a careful parameter restore and quick SERCOS ring check.

Advantages & Value

• Seamless retrofit – Often a drop‑in replacement in existing Rexroth DIAX/IndraDrive systems, minimizing downtime.
• Stable motion performance – Deterministic SERCOS synchronization for multi‑axis machines that need consistent cycle timing.
• Flexible field connectivity – PROFIBUS‑DP keeps legacy I/O, HMIs, and PLCs talking without a control system overhaul.
• Cost control – Firmware licensed per needs; avoid over‑spec if your application doesn’t require extended options.
• Serviceability – Clear diagnostic behavior and a simple service port shorten troubleshooting in most cases.

Installation & Maintenance

• Environment – Mount in a closed, ventilated cabinet; keep ambient 0–45 °C; allow airflow and clearance above/below the unit.
• Power & grounding – 24 VDC supply with proper polarity and protective earth. Use clean control power; isolate from high‑noise loads where possible.
• Fiber & fieldbus – Route SERCOS fibers respecting bend radius and connector cleanliness; verify PROFIBUS termination and address settings.
• Wiring – Separate signal/fiber paths from motor and mains conductors; use ferrules; label everything to simplify service.
• Routine care – Periodic dust cleaning, connector re‑seating checks, and backup/restore of parameters. Apply firmware updates that match your validated machine version—avoid mixing major revisions mid‑production without re‑qualification.
• Spare strategy – Keep a pre‑configured spare on the shelf with a current parameter image; it typically cuts replacement time to under an hour.

Quality & Certifications

• CE conformity; UL recognition/certification is common for Rexroth industrial controls
• Manufactured under ISO 9001 quality systems
• RoHS-compliant in most deliveries (region dependent)
• Warranty: 365 days (our supply terms)

Compatible & Supporting Components

• Rexroth DIAX/IndraDrive servo drives with SERCOS interface (e.g., DKC, DDS/HDS families)
• PROFIBUS‑DP remote I/O modules and operator panels
• SERCOS fiber‑optic patch cables and transceivers (per Rexroth specs)
• 24 VDC industrial power supplies with sufficient headroom for control loads

If you’re replacing a failed controller, I typically recommend sharing a photo of the nameplate and your current firmware label. It helps confirm the exact P2 interface and avoids surprises during commissioning.
