Important: Omron servo drives may include different versions. Feel free to contact us regarding the different software and hardware specifications.

Our repair process is preventive and includes a series of steps to ensure high repair quality.

Fault Analysis and Localization

What can you do?

Handling Parameters

When parameterizing, it is crucial to secure the settings early and document jumper and key settings.

In most cases, motor parameters are stored in the drive or control.

What should you pay attention to when parameterizing?

In most cases, motor parameters are stored in the drive or control.
Obtain the relevant documentation or software for setting the parameters.
You can find more documentation on this topic at the end of this page or ask us.

The Typical Process of Repairing Omron Servo Drives and Omron Servo Motors

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

Many of our customers have defective devices of the same model in larger quantities. We have optimized our processes for series repair and have the capacity to repair many devices in parallel quickly and to a high repair many devices in parallel.

Cost & Warranty

How much does a repair or overhaul of a device cost? What does "flat repair rate/standard repair price" mean?

The repair process itself represents a high degree of technical complexity, which we always want to master with a qualitative and long-term solution for you. solution for you. However, the maintenance of these quality characteristics requires, to agree on a repair flat rate or standard repair price. We communicate honestly and transparently all the information you need. For example, prices, previous and completed work steps, delivery times, etc.

Is there a warranty for the respective repair?

Basically we give 12 months warranty.
