Error Analysis and Localization
What can you do?
Possible Causes of Errors in Servo Modules
Possible Solutions and Tips
- Test the motor by reconnecting it.
- Check cable connections.
- Run in jog mode without load.
If these actions 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, which is available for download at the end of this page.
Possible Solutions and Tips
- Warm the device with an external source. If it turns on, this indicates a weak power supply that needs repair.
- Check fuses.
- Check the power supply of 3 x 200 or 220 volts depending on the model.
Further error messages can be found in the alarm list, which is available for download at the end of this page.
Possible Solutions and Tips
- Free the motor from the shaft or belt and test it at different speeds.
- Disconnect the motor connection cables and completely free the motor from load. Then turn it by hand.
If the motor is still stiff or makes unusual noises, the ball bearings may be defective. - Check motor insulation and windings for flashovers.
- Check the encoder.
Further error messages can be found in the alarm list, which is available for download at the end of the form.
Possible Solutions and Tips
- Visually inspect the encoder area for dirt, and if necessary, have it cleaned by a specialized company.
- Check encoder signals: For older motors with analog encoders, read sinusoidal diagrams with an oscilloscope.
For serial encoders, check the operating voltages as well. - Have the encoder replaced.

The Typical Repair Process for Okuma Servo and Spindle Drives, as well as Spindle Motors
The repair process includes the following steps:
Servo and Spindle Drives
- Preventive overhaul - replacing all necessary defective and worn-out parts.
- Intensive cleaning.
- Comprehensive final and load tests on our test benches.
- Parameter matching or restoration of parameters.
- Completion of documentation and checklists.
Spindle Motors
- Preventive overhaul - replacing all necessary defective and worn-out parts. Renewing ball bearings and seals.
- Intensive cleaning, stripping paint, 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
The following spare parts are replaced:
Servo and Spindle Drives
- Electrolytic capacitors
- Large buffer capacitors
- Relays
- Current measuring modules
- Optocouplers
Spindle Motors
- Encoders
- Encoder cables
- Encoder connectors
- Resolvers
- Brakes
- Ball bearings
- Shaft seals
- O-rings
- Power cables
- Power connectors
Additionally, we replace certain components that have proven to be particularly prone to failure over multiple repairs and are therefore replaced preventively based on our extensive experience.
To avoid shortages and discontinuations, we have process-oriented software solutions that monitor our inventory. We order some parts in advance, and for serial repairs, we even secure enough spare parts for a year to always have access to a large stock.
Quality and Level of Repair
The test is conducted on a test bench that simulates the processes as in a real processing plant.
For Servo and Spindle Drives
- BUS control
- POT/NOT (positive and negative over travel)
- Encoder connection
- Alarm states
- Speed
- Current and voltage consumption
- Temperature
- Parameters
For Spindle Motors
- Encoder connection
- Alarm states
- Speed
- Current and voltage consumption
- Temperature
- Vibration
- Noise level
We are continuously expanding our repair portfolio with new series

As drive and power electronics are often discontinued prematurely, you may be under pressure to deliver replacement parts to your customers on time. We assist 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
- Re-development or re-engineering of modules or complete devices if necessary
