Yaskawa GA800 F010 Fault — What It Means
The F010 fault code does not appear in available Yaskawa GA800 documentation. The GA800 maintenance manual does not list F010 as a valid error code for this drive series. In other manufacturer’s equipment (specifically Siemens Masterdrive systems), F010 indicates DC link overvoltage, but this definition cannot be applied to the Yaskawa GA800 without confirmation. If you are seeing F010 on your GA800 display, the code may be misread, the drive may be a different model, or it could be a non-standard alarm specific to your system configuration.
Because no verified meaning exists for F010 on the GA800, troubleshooting must begin with confirming the exact fault code displayed. Check your drive’s operator panel carefully and record the complete alarm or fault number. The Yaskawa GA800 Technical Manual (document series SIEPC*) contains the authoritative fault code table for your drive, and Yaskawa Technical Support can confirm whether F010 is valid for your specific firmware version and configuration. Do not attempt repairs based on fault codes from other manufacturers or drive families.
Before You Replace Anything
Do not replace control boards or power modules based on an unverified fault code. Contact Yaskawa Technical Support with your drive’s model number, serial number, and exact displayed fault to confirm the code is valid before ordering any parts.
Common Causes
- Misread or incorrect fault code (~40%) The displayed code may be a different alphanumeric combination that resembles F010, or the drive may be a model other than the GA800.
- Firmware-specific or configuration alarm (~30%) Some GA800 firmware versions or custom configurations may use non-standard fault codes not listed in general documentation.
- Cross-reference with wrong manufacturer (~20%) F010 is a documented Siemens Masterdrive fault (DC link overvoltage), and technicians may mistakenly apply Siemens troubleshooting to Yaskawa drives.
- Display or control board error (~10%) A failing operator panel or control board can show garbled or invalid fault codes that do not correspond to actual drive faults.
Quick Diagnosis
Answer these to narrow it down fast.
Does your drive nameplate confirm it is a Yaskawa GA800 series?
No: Identify the correct drive manufacturer and model, then consult that manufacturer's fault code documentation.
Is the fault code displayed as exactly 'F010' with no other characters or symbols?
No: Write down the complete fault code including all letters, numbers, and symbols, then look it up in the GA800 Technical Manual or contact support.
Do you have access to the GA800 Technical Manual (SIEPC* series) for your drive?
No: Contact Yaskawa Technical Support or your drive supplier to obtain the correct technical manual and verify the fault code definition.
Step-by-Step Fix
- Power down the drive safely following lockout/tagout procedures and wait for the DC bus to discharge before performing any inspection.
- Record the complete fault information from the operator display, including the exact code, any accompanying text, and any other alarms or warnings shown.
- Verify the drive model by reading the nameplate on the drive enclosure and confirming it is a Yaskawa GA800 series VFD, not a different manufacturer or model.
- Consult the GA800 Technical Manual (document series SIEPC*) and locate the fault code table to see if F010 is listed for your drive’s firmware version.
- Contact Yaskawa Technical Support with your drive’s complete model number, serial number, and the exact fault code to confirm whether F010 is valid and obtain the correct troubleshooting procedure.
- Do not attempt component replacement until you have confirmed the fault code definition and followed manufacturer-recommended diagnostics, as the GA800 maintenance manual limits user repair to fan and control board replacement only.
- If the fault is confirmed as DC overvoltage (based on manufacturer confirmation, not assumption), check supply voltage, inspect for regenerative braking conditions, and verify braking resistor operation per Yaskawa guidance.
Parts Often Needed
| Part | Notes |
|---|---|
| Yaskawa GA800 Control Board | Amazon | Only replace if Yaskawa support confirms a control board fault after verifying the code definition; the GA800 maintenance manual lists the control board as a user-replaceable component. |
| Yaskawa GA800 Cooling Fan | Amazon | User-replaceable per the GA800 maintenance manual; relevant only if overheating is confirmed as a contributing factor after fault verification. |
When to Call a Pro
Call a qualified VFD technician or contact Yaskawa Technical Support immediately if you see F010 or any unrecognized fault code on your GA800 drive. The GA800 maintenance manual explicitly states that repair information is limited to fan and control board replacement, and all other service must follow the GA800 Technical Manual or manufacturer guidance. Do not attempt to diagnose or repair high-voltage VFD components without proper training and safety equipment. A professional with access to Yaskawa technical resources can verify the fault code, perform proper diagnostics, and determine whether the issue is a supply problem, a drive component failure, or a configuration error. VFD troubleshooting requires specialized knowledge of DC bus operation, inverter circuits, and regenerative braking, and incorrect repairs can damage the drive or create safety hazards.
