FANUC Drive Repair & Servo Drive Testing
FANUC Drive Repair and Testing
Fletcher Moorland have been servicing Fanuc drives for over 20 years. As part of a major upgrade in our automation repair department, we have combined our Fanuc drives test rig into one universal Fanuc test rig. This is probably the most complete Fanuc drives test facility around, giving us the ability to fully test the entire alpha series of drives. From the low voltage wire controlled alpha drives & PSU, to the High voltage Optical FSSB controlled units including the Spindle types too.
We’ve managed to combine this rig by using a Fanuc PLC giving the motion control signals (either wired or optical FSSB to the drive and running a test routine as would be seen on a CNC or machine.
It gives us and our customers confidence a repair that has been fully tested not just ‘powered up’ as a number of our competitors are limited to.
As with all our repairs, Fanuc drives come with a 12 month ‘in service’ warranty.
Specialist FANUC Drive Testing
Testing is an important part of diagnosing drive faults and verifying equipment operation. Our FANUC drive test-rig capability supports the assessment of compatible units, helping our engineers investigate faults and evaluate drive performance.
For maintenance engineers and production teams, specialist testing can provide valuable information when a drive has failed, is behaving intermittently or needs assessment before being returned to service.
The available testing depends on the particular drive model and the capabilities of the test configuration.
FANUC Drive Fault Diagnosis and Repair
A faulty drive can interrupt machine operation, affect production schedules and put pressure on maintenance teams.
Our engineers assess industrial electronic equipment to identify faults and determine an appropriate repair solution. Where repair is viable, this can offer an alternative to replacing the complete unit.
If your FANUC drive is displaying an alarm, failing to operate correctly or suffering from an intermittent fault, provide the drive model, any fault codes and a description of the symptoms when you contact us
What Information Should You Provide?
To help us assess your FANUC drive enquiry, please provide:
- Drive model and part number
- Any alarm or fault codes displayed
- A description of the symptoms
- Details of the machine or application
- Whether the fault is continuous or intermittent
Photographs of the unit and its identification plate can also help our team understand your requirements.
If a FANUC drive is affecting your production, speak to Fletcher Moorland about assessment and repair options.
Our team can discuss your equipment, the fault symptoms and the next steps.
