Error Analysis and Localization

What Can You Do?

Servo Motor Errors

Possible Solutions and Tips

Replace the motor as a test.
Check cable connections.
Disconnect the motor from the shaft or belt and test at different speeds.
Check or replace the drive.
Perform an insulation test on the motor.
Visually inspect the motor.
Visually inspect the encoder area for contamination, optionally have it cleaned by a specialized company.
Check encoder signals: For older motors with analog encoders, read the sine diagrams with an oscilloscope.
For serial encoders, also check the operating voltages.

If these measures do not help, the error is usually due to a faulty encoder or worn-out bearings.

More error messages can be found in the alarm list, which is available for download at the end of the form.

Possible Solutions and Tips

Disconnect the motor from the shaft or belt and test at different speeds.
Disconnect the motor connection cables and completely relieve the motor of loads. Then turn it by hand.
If the motor is still stiff or makes unusual noises, the bearings may be defective.
Check the motor insulation and windings for breakdown.
Check the encoder.

Handling Parameters

During parameterization, it is crucial to secure settings early and document jumper and key settings as well.

Parameter being set on the device

What should you pay attention to during parameterization?

In most cases, motor parameters are stored in the drive or the controller.
Obtain the necessary documentation or software for parameter setting.
Additional documentation on this topic can be found at the end of this page or feel free to contact us directly.

Typical Repair Process for Yaskawa Drive Motors

The repair process for servo motors includes the following steps:

Preventive overhaul - Replacement of all necessary defective and worn parts. Renewal of ball bearings and seals.
Thorough cleaning, stripping, and degreasing.
Repainting.
Comprehensive final and long-term tests on our test benches followed by final adjustments.
Completion of documentation and checklists.

High-Quality Spare Parts for High-Quality Repairs

For Yaskawa drive motors, we replace:

Encoders
Encoder cables
Encoder connectors
Resolvers
Brakes
Ball bearings
Shaft seals
O-rings
Power cables
Power connectors

Additionally, we proactively replace certain components that have proven to be susceptible due to recurring defects.

To prevent shortages and product discontinuations, we monitor our inventory using process-oriented software solutions. We order some parts in advance and even stock up on sufficient spare parts for a year for series repairs.

Quality and Level of Repair

A professional repair requires the use of a test stand. For each new series, specifically adapted and complex test equipment is developed. The devices are thoroughly checked for functionality by undergoing a long-term load test.

The test is conducted on a test stand that simulates processes as in a real machining facility.

During the test:

Encoder connection
Alarm states
Speed
Current and voltage consumption
Temperature
Vibration
Noise level

We continuously expand our repair portfolio with new series

As drive and power electronics are often discontinued prematurely, you may find yourself under pressure to provide timely replacements to your customers. We assist you in analyzing bottlenecks and work together on optimal solutions.

Typical processes include:

Development of test stands and procedures
Organization of spare parts
Preventive repair at the component level
If necessary, new development 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:

Preventive overhaul - replacement of all necessary defective and used parts. e.g. ball bearings, plugs, seals, encoders and brakes.
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 motor 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

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.

Questions & Answers

Is the estimate free of charge?

Entrance tests at the test site up to 30 minutes in length are free of charge. If further tests or examinations at component level are necessary, we will inform you of the expected effort and ask for approval.

What does a “standard repair” involve?

More about standard repair

What are the lead times for standard repairs?

A standard repair usually takes 4-7 working days after approval of the estimate. Faster throughput times for smaller servo drives or express repairs are often feasible within two working days.
