Can you repair all Sieb & Meyer high-frequency drives?

We support a wide range of Sieb & Meyer high-frequency converters used in high-speed motor applications. Most repairs involve power stage components, control boards, IGBT modules, DC bus sections, or faulted feedback circuits.

Each unit undergoes full diagnostic testing, component-level repair (when viable), and load validation before return shipment. If a repair is not technically or economically feasible, we will recommend a replacement strategy.

How quickly can you turn around a Sieb & Meyer drive repair?

Turnaround time depends on failure mode, parts availability, and testing requirements. Because these drives operate at high switching frequencies and elevated RPM ranges, proper validation cannot be rushed.

For critical downtime situations, we can prioritize diagnostics and provide rapid failure assessment so you can determine whether repair or replacement is the best path forward.

Do you offer replacement options if my Sieb & Meyer drive is obsolete?

Yes. When a Sieb & Meyer drive is obsolete or no longer economically repairable, we provide engineered replacement solutions tailored to your existing machine architecture. Replacement is not simply a matter of swapping hardware. We evaluate motor electrical characteristics, feedback configuration, control interface requirements, enclosure constraints, and operating speed range to ensure compatibility and performance continuity.

If required, we support parameter migration, system integration, and commissioning to ensure the new drive performs correctly within your application. The goal is not just to restore operation, but to deliver stable, repeatable performance under full production load.

Can you support on-site troubleshooting for drive faults?

Yes. While many issues can be diagnosed remotely or resolved through in-house repair, certain high-speed applications require live system evaluation. In these cases, we provide on-site technical support to diagnose complex faults within the context of the full machine environment.

On-site support may involve real-time fault analysis, waveform evaluation, thermal assessment under load, and integration troubleshooting between the drive, motor, and control system. Our approach is methodical and engineering-driven, focused on isolating root cause rather than addressing symptoms. This ensures the issue is resolved at the system level, minimizing repeat failures and unplanned downtime.
