Fault Analysis and Localization

What can you do?

Handling Parameters

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

What should be considered when configuring parameters?

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

The Typical Repair Process for Yaskawa Servo Modules

The Repair Process for Servo Modules Includes the Following Steps

Preventive Overhaul - Replacement of all necessary defective and worn parts.
Intensive Cleaning.
Comprehensive Final and Load Testing on Our Test Benches.
Parameter Matching or Restoration of Parameters.
Completion of Documentation and Checklists.

High-Quality Spare Parts for High-Quality Repairs

For Yaskawa Sigma V Servodrives, We Replace

Electrolytic capacitors
Large buffer capacitors
Relays
Current measuring modules
Optocouplers

Additionally, we replace certain parts that have statistically proven to be prone to failure over multiple repairs, selected based on this data.

To counteract shortages and obsolescence, we utilize process-oriented software solutions that monitor our inventory. We pre-order certain parts, and for series repairs, we secure sufficient spare parts for up to a year to ensure constant availability.

Quality and Level of Repair

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

The test is conducted on a test bench that simulates operations as in a real processing plant.

The following are 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 phased out prematurely, you may be under 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 repairs at the component level
If necessary, redesign or re-engineering of modules or entire devices

Frequently Asked Questions

Drive module 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 drive modules?

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

Preventive overhaul - replacement of all necessary defective and used parts. E.g. electrolytic capacitors, transistors, optoelectronic components.
Intensive cleaning
Extensive final and load tests on our test stands
Parameter adjustment or parameter recovery

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

Further information

What is the meaning of letters and numbers in the type designation

For a better understanding of all the options, which can be found in the type designation, we offer you a separate configurator.

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

What are the costs for repair or overhaul? What does "flat repair rate or 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.
