The repair process for Omron servo drives and Omron servo motors includes the following steps

Preventive overhaul - replacement of all necessary defective and worn parts.
Intensive cleaning.
Comprehensive final and stress tests on our test benches.
Parameter matching or parameter recovery.
Completion of documentation and checklists.

High-Quality Spare Parts for High-Quality Repairs

For Omron servo drives and servo motors, we replace

Electrolytic capacitors
Large buffer capacitors
Relays
Current sensing modules
Optocouplers

Additionally, we replace certain parts that have been statistically identified as frequently failing after multiple repairs.

To counteract shortages and discontinuations, we use process-oriented software solutions that monitor our inventory. We pre-order some parts, and for serial repairs, we secure sufficient spare parts for up to one year to ensure access to a large stock at any time.

Quality and Level of Repair

A professional repair requires the use of a test system. For each new series, a specially adapted and complex test setup is developed. The devices are thoroughly tested for functionality by subjecting them to long-term stress tests.

The test is carried out on a test bench that simulates processes as in a real processing plant.

The following is tested:

BUS control
POT/NOT (positive and negative over travel)
Encoder connection
Alarm states
Speed
Current and voltage consumption
Temperature
Parameters

We continuously expand our repair portfolio with new series

Since drive and power electronics are often discontinued prematurely, you may feel pressure to deliver replacements to your customers on time. We support you in analyzing bottlenecks and work together on optimal solutions.

The typical process includes:

Development of test benches and procedures
Organization of spare parts
Preventive repair at the component level
If necessary, redevelopment or re-engineering of modules or complete devices

Frequently Asked Questions

Motor repair

In which quality/level are load tests performed at your company?

Complex and specially adapted test equipment is developed for each new series. Devices are tested with long-term load test thoroughly checked for functionality. Get an idea of our test facilities.

Do you have special spare parts, which are necessary for qualitative repair?

In times of shortages and discontinuations, we have process-oriented software solutions that monitor our inventories. We order some parts in advance, for series repairs even for 1 year, so that we can fall back on a large stock of spare parts. Certain modules are re-engineered by us.

Can you parameterize the devices?

If possible, a copy of the parameters is always read out and stored upon receipt. After successful repair, the data is compared and in case of exchange or sale, original parameters are transferred or restored to the new device. We have all the necessary hardware as well as software applications to parameterize Yaskawa devices according to the specifications.

What processes are involved in the repair of motors?

The repair process for motors includes, but is not limited to, the following:

New and fine adjustment of encoder/encoder systems
As needed winding repair and balancing
As needed connector repair or replacement
For irreparable equipment, an alternative solution will be offered (e.g. replacement or sale)

You can find more information on the process flow for motor repair here.

Further information

Will I get a detailed repair report after a successful repair?

We document the repair process for every order. You can download a detailed description of the process here.

Do you commission new or unknown equipment?

We are continuously looking for new areas of activity. After consultation with the customer, we determine the necessary steps for a safe and qualitative repair

Can it happen that after repair my device continues to show errors?

It may happen that error messages continue to be displayed with the connected device. Already during the analysis of the errors, we give the customers suggestions for solutions for different malfunctions and errors. error cases, if we suspect further error causes. Errors and faults are documented, among other things, in the log file of the respective device, which may indicate, for example, encoder communication problems, cable defects or overloads.

What does serial repair or overhaul mean

We Verify Your Drives and Electronic Components for Authenticity

Authenticity Check for Drives & Electronic Components: Confidence Before You Invest

Prevent failures caused by hidden counterfeits.
With our professional authenticity verification, you ensure that your drives and system components truly meet original manufacturer quality before being installed in critical processes.

Why Authenticity Check Is Essential Today

The market for industrial drives, motors, and control components is globally interconnected. Components are traded through various channels, new, used, refurbished, or from warehouse stock.

As shown in our article Solutions Against Counterfeit Drive Components, products with unclear origin or altered substance repeatedly enter industrial supply chains.

For buyers, it is often not clearly recognizable:

Whether it is an original product from the manufacturer
Whether the device has been opened or technically modified
Whether serial numbers and nameplates are authentic
Whether all components correspond to the original condition

Especially in production-critical systems, unverified components can lead to downtime or consequential damage.

Professional authenticity verification provides clarity before the component is installed or resold.

What Exactly Is Checked During Authenticity Check?

Inspection of Nameplate and Serial Number

We compare serial numbers, production markings, and device designations with our technical reference data and manufacturer standards, checking them for plausibility and irregularities.

Visual and Mechanical Inspection

Our technicians professionally open the device and examine housing, screws, seals, connectors, and internal assemblies for signs of manipulation, replacement traces, or deviations from the original condition.

Electrical Measurements and Functional Testing

We test power and control units on our test benches under realistic conditions and verify whether the technical parameters comply with manufacturer specifications.

Software and Parameter Analysis

By reading firmware versions, parameters, and internal device data, we identify modifications, non-original configurations, or inconsistent software versions.

Comprehensive Technical Evaluation

Based on all inspections, we prepare a well-founded overall assessment, transparently document the device condition, and provide you with a clear recommendation for further use, repair, or replacement.

Who Our Authenticity Check Is the Right Choice For
