Rexroth PPC-R22.1N-T-Q2-G2-NN-FW – Modular Motion/Logic Controller for Multi-Axis Machines
The Rexroth Indramat PPC-R22.1N-T-Q2-G2-NN-FW is a rack-mounted motion/logic controller module designed for coordinated multi‑axis applications. From my experience, the PPC‑R platform is typically selected when you want reliable SERCOS-based drive control with deterministic timing in packaging, printing, and general automation lines. The “-FW” suffix indicates the firmware is supplied/ordered separately, which makes sense if you need a specific technology package or version aligned to your machine standard.

Key Features
- Rack-mounted PPC-R controller – Fits Rexroth’s modular rack system for clean cabinet integration and easy service access.
- SERCOS-based multi-axis control – Typically used to coordinate Rexroth servo drives (EcoDrive/DIAX and, in many cases, IndraDrive) with deterministic motion profiles.
- Option set T / Q2 / G2 – This configuration provides a technology variant with extended connectivity; you might notice improved fieldbus/drive interface flexibility compared with base units.
- Service interface for commissioning – Serial service port is commonly used for setup, diagnostics, and firmware loading.
- Firmware managed separately (-FW) – Lets you match the exact firmware level to your line’s installed base or validation requirements.
- 24 VDC control power – Standard cabinet supply, keeping wiring straightforward and maintenance predictable.
Technical Specifications
| Brand / Model | Rexroth Indramat PPC-R22.1N-T-Q2-G2-NN-FW |
| HS Code | 8537.10 (Programmable controllers/control panels, ≤1000 V) |
| Power Requirements | 24 VDC nominal (control power), cabinet supply with protective earth |
| Operating Temperature | Typically 0–45°C in a closed control cabinet; non‑condensing humidity |
| Signal I/O Types | Digital/analog I/O via expansion modules; motion commands over SERCOS |
| Communication Interfaces | SERCOS (master) for drives; serial service port (RS‑232) for commissioning; additional options per Q2/G2 set |
| Installation Method | Rack-mounted module within a control cabinet; front access for wiring/service |
| Firmware | Ordered/loaded separately (-FW), match to your technology package |
Application Fields
This model is well-suited for multi-axis motion control where synchronized profiles matter:
- Packaging machinery (form-fill-seal, cartoning, labeling) needing tightly synchronized axes
- Printing and converting with registration control and web handling
- Material handling and assembly cells requiring deterministic motion sequences
- Medium-complexity machine tools and special-purpose machines using SERCOS drive trains
One thing I appreciate is how stable these PPC‑R units run once the firmware and SERCOS topology are locked down—downtime is typically very low in mature lines.
Advantages & Value
- Proven reliability – These controllers have a reputation for long service life in 24/7 plants.
- Compatibility – Works with Rexroth SERCOS-based servo systems, which helps when you’re upgrading drives but keeping existing machine logic.
- Lifecycle cost control – Reusing the same firmware track (-FW) across lines often simplifies validation and reduces engineering time.
- Serviceability – Rack format makes swaps quick; serial service interface is straightforward for diagnostics.
A maintenance manager recently told us the biggest win was “no surprises during shift change.” Once configured, the PPC‑R behavior is consistent, which seems to be what most teams want in production.
Installation & Maintenance
- Control cabinet – Mount in a clean, ventilated enclosure; follow EN 60204‑1 wiring and grounding practices.
- Power & grounding – 24 VDC stabilized supply with proper PE; keep return paths short and use dedicated control power circuits.
- Shielded motion networks – Use shielded fiber/cables for SERCOS; segregate from high‑power cables to reduce EMI.
- Thermal management – Maintain airflow around the rack; avoid hot spots from adjacent drives or transformers.
- Routine care – Periodically back up parameters, inspect connectors, clean dust with dry air, and review firmware revision consistency across assets.
- Safety – De-energize before module changes; verify SERCOS ring integrity and safe torque off (STO) wiring on the drives as applicable.
Quality & Certifications
- CE conformity for EMC and Low Voltage (typical for the PPC‑R family)
- UL/cUL listing for control equipment (region-dependent)
- RoHS compliance where applicable (varies by production year and regional market)
- Manufacturer warranty support; unit supplied with 365‑day seller warranty
If you’re replacing an existing PPC‑R module, share your current firmware label and drive lineup. Matching the -FW level and SERCOS topology usually shortens commissioning to a single maintenance window.
