Failure Analysis and Localization

What can you do?

Faults in Fanuc Servo and Spindle Drives

Possible solutions and tips

  • Warm the device with an external source. If it then switches on, this indicates a weak power supply that needs repair.
  • Check fuses
  • Verify power supply of 3 x 200 or 220 volts, depending on the model.

Further error messages can be found in the alarm list available for download at the end of this page.

Possible solutions and tips

  • Replace the motor as a test.
  • Check cable connections.
  • Run in jog mode without load.

If these measures do not help, the error is usually in the power stage of the drive module.

Further error messages can be found in the alarm list available for download at the end of this page.

The typical process of repairing Fanuc servo and spindle drives

The repair process for Fanuc servo and spindle drives as well as power supplies includes the following steps:

  • Thorough cleaning.
  • Preventive maintenance - replacement of all necessary defective and worn-out parts.
  • Comprehensive final and load testing on our specialized Fanuc test benches.
  • Completion of documentation and checklists.

High-quality spare parts for high-quality repairs

For Fanuc servo and spindle drives, we replace

  • Electrolytic capacitors
  • Large buffer capacitors
  • Relays
  • Current measuring modules
  • Optocouplers

Additionally, we replace certain parts that have proven to fail frequently during multiple repairs and are therefore statistically selected for replacement.

To counter shortages and discontinuations, we use process-oriented software solutions that monitor our inventory. We order some parts in advance, and for series repairs, we even secure sufficient spare parts for a year to ensure access to a large stock at all times.

Quality and standard of repair

Professional repair requires the use of a testing facility. Fanuc servo and spindle drives are inspected and subjected to long-term tests at a specially equipped test station.

The following aspects are extensively tested:

  • Control (computer to drive module)
  • Alarm states
  • Speed (min. & max.)
  • Current and voltage consumption
  • Temperature

We continuously expand our repair portfolio with new series

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

The typical process includes:

  • Development of test stations and procedures
  • Organization of spare parts
  • Preventive repair at component level
  • If necessary, redevelopment 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:
  • 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 drive module 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

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.
