Siemens SINAMICS repair

Expert Repair Guide for Technicians

Is your Siemens SINAMICS drive causing unexpected downtime and threatening your production schedule? Even premium industrial components reach the end of their operational lifecycle, leading to system failures and reduced efficiency. SINAMICS servo drives serve critical functions across industrial sectors – from assembly and packaging operations to cranes, paper processing, plastics manufacturing, and precision machine tools.

Our specialized repair center focuses exclusively on Siemens servo drive restoration. We bring 25 years of hands-on experience to every repair, giving our customers reliable alternatives for maintaining their manufacturing systems. Our service scope spans the complete equipment lifecycle – routine maintenance, fault diagnosis, component replacement, and performance optimization.

Rather than replacing expensive drives, our technicians perform manufacturer-level analysis and repair work to extend your equipment’s operational life. This repair-first approach delivers significant cost savings. It is also more sustainable to repair defective industrial drives than to replace them with new units.

We stand behind our expertise with reliable turnaround times and quality workmanship that keeps your operations running smoothly.

Repair process

Our Siemens SINAMICS drive repair follows a structured approach to ensure reliable results. Each repair begins with proper preparation and safety protocols.

  • Equipment preparation – We assemble all required tools: multimeter, precision screwdriver set, and verified replacement components before starting any diagnostic work.
  • Safety isolation – Complete power disconnection from all sources prevents accidents and protects both technicians and equipment from further damage.
  • Visual inspection – Our technicians examine the drive for burnt components, loose connections, damaged wiring, and other visible faults.
  • Electrical testing – Precision instruments verify continuity and measure voltage levels against Siemens technical specifications.
  • Component replacement – Faulty parts are replaced with high-quality components that meet manufacturer standards.
  • Connection verification – All electrical connections receive thorough inspection to ensure proper securing and contact integrity.
  • Performance testing – Rigorous functional testing confirms the repair has resolved the original fault condition.
  • Documentation – Complete repair records detail all replaced components and modifications for future reference.

Common Siemens SINAMICS Drive Faults We Fix

SINAMICS drive repair demands specialized knowledge of fault diagnostics and resolution procedures. Our service technicians encounter and resolve these complex drive issues on a daily basis.

  • DC link voltage problems represent the most frequent power supply faults we see. Fault code F30002 signals DC link overvoltage, typically triggered by excessive regenerative energy during deceleration or braking. F30003 indicates DC link undervoltage, usually caused by main supply interruptions or sudden shock loads.
  • Heat-related failures require immediate attention. F30004 appears when heat sink temperatures exceed operational limits. Control module overtemperature errors (N01009) can cause permanent component damage if not addressed promptly.
  • Ground fault conditions (F30021) require systematic inspection of power cables and motor windings. Our diagnostic equipment precisely identifies the fault location and underlying cause.
  • Encoder malfunctions present unique challenges. Feedback loss errors (F00090) and speed plausibility faults (F31118) need careful calibration and connection verification.
  • DRIVE-CLiQ communication failures (F30885) often point to power module problems.
  • Motor-related faults include overspeed conditions (F7901) and thermal protection trips (F00011).
  • Firmware corruption issues are resolved using official Siemens updates and manufacturer-approved procedures .
