Yaskawa GA800 E17 Fault — What It Means
E17 does not appear in the standard Yaskawa GA800 fault code table according to manufacturer documentation. This code may be a misread display (such as a different fault shown at an angle), a communication alarm, or a code from a connected keypad or operator interface rather than the drive itself. It could also indicate a region-specific code or a custom parameter alarm set by the integrator. The GA800 uses alphanumeric fault codes, and verifying the exact characters on the display is the first step.
Yaskawa documentation instructs technicians to identify the fault from the drive’s alarm history, remove the underlying cause, and then reset the fault from the keypad. The drive will not resume operation until the condition that triggered the alarm is corrected and the reset procedure is completed.
Common Causes
- Misread or misidentified fault code The display may show a similar code like E.17, F17, or A17, or the code may belong to a connected operator panel rather than the drive itself.
- Communication alarm from external device The code may originate from a connected keypad, PLC, or network device rather than the GA800 drive.
- Custom parameter or user-defined alarm The integrator or system designer may have programmed a custom alarm code that does not appear in standard Yaskawa tables.
- Regional or software version variation Some drive firmware versions or regional models may use codes not listed in general documentation.
- Display or control board fault A failing keypad or control board can display incorrect or phantom fault codes that do not correspond to actual drive conditions.
Step-by-Step Fix
- Verify the exact fault code by viewing the alarm history on the keypad (consult your GA800 manual for accessing the alarm log) and write down the complete alphanumeric sequence including any decimals or letters.
- Check the drive nameplate for the catalog code and model number to confirm you are referencing the correct manual and fault table for your specific GA800 variant.
- Consult the fault code table in your drive’s installation or technical manual to match the verified code, and note that E17 does not appear in standard GA800 tables.
- Inspect external devices including keypads, operator interfaces, PLCs, and communication modules to determine if the code originates from a connected device rather than the drive.
- Power cycle the drive by switching off input power, waiting 60 seconds for capacitors to discharge, then restoring power to see if the code clears or changes.
- Attempt a keypad reset after identifying and clearing the cause by following the reset procedure in your manual (Yaskawa requires the fault cause to be removed before reset will succeed).
- Contact the system integrator or Yaskawa support with your drive’s catalog number, alarm history printout, and the exact displayed code to identify the source if the code remains unidentified.
Parts Often Needed
| Part | Notes |
|---|---|
| Yaskawa GA800 control board | Amazon | Replacement supported by manufacturer if display or control logic faults are confirmed. |
| Yaskawa GA800 cooling fan | Amazon | Field-replaceable component per manufacturer maintenance guide if drive shows thermal issues. |
When to Call a Pro
Call a qualified drive technician or contact Yaskawa technical support if you cannot verify the fault code in your manual, if the code persists after power cycling and inspection, or if you are not trained in VFD diagnostics. The GA800 maintenance guide limits field repair to fan and control board replacement only, and attempting other repairs voids warranties and creates shock hazards. A professional can access Yaskawa’s full fault database, retrieve detailed alarm logs, and identify custom or communication-related codes that do not appear in standard documentation.
