Yaskawa GA800 E14 Fault — What It Means
E14 does not appear in the official Yaskawa GA800 fault and alarm code tables provided in the manufacturer documentation. The GA800 uses fault codes for conditions like overcurrent, overvoltage, and communication errors, but E14 is not listed among them. If your keypad is displaying E14, you may be looking at a different drive model, a PLC or servo alarm, or misreading the displayed code.
Yaskawa’s standard procedure for any GA800 fault is to identify the exact code shown on the keypad, consult the fault table in the manual that matches your drive’s catalog number, remove the cause of the fault, and then reset the drive. Without confirmation that E14 is a valid GA800 code, any repair attempt should start by verifying the drive model and checking the correct manual.
Common Causes
- Misidentified drive model The fault code may belong to a different Yaskawa product line or another manufacturer’s equipment.
- Misread display The keypad may be showing a different alphanumeric code that resembles E14 but is actually a documented GA800 fault.
- Incorrect manual reference Using a manual for a different drive series can lead to confusion over fault code meanings and repair steps.
- Custom parameter or communication alarm Some installations use custom alarms or network diagnostics that may display non-standard codes.
Step-by-Step Fix
- Verify the drive model by reading the nameplate or catalog code on the drive itself and confirm it is a GA800 series unit.
- Check the keypad display carefully and write down the exact fault or alarm code, including all letters and numbers, to avoid misreading.
- Locate the correct manual for your specific GA800 catalog number and turn to the fault and alarm code table in that document.
- Cross-reference the displayed code in the table to find the official description and recommended corrective action from Yaskawa.
- Remove the cause of the fault as directed in the manual, which may involve checking wiring, motor parameters, or power supply conditions.
- Reset the drive from the keypad according to the manual procedure after the underlying problem has been addressed.
- Contact Yaskawa Technical Support with your drive model number, serial number, and the exact fault code if it does not match any entry in the official table.

When to Call a Pro
Call a qualified drive technician or contact Yaskawa Technical Support if you cannot locate E14 in your GA800 manual, if the fault persists after following the manual’s corrective steps, or if you need help identifying the correct drive model and fault table. Yaskawa’s maintenance documentation states that repair guidance beyond fan and control board replacement is limited and recommends professional support for undefined or recurring faults.
