Driver Error
Omron · MX2 Inverter
What does E30 mean?
This fault is triggered by an instantaneous overcurrent event in the IGBT (Insulated Gate Bipolar Transistor) output stage of the inverter. It signifies a rapid and severe current spike that could damage the IGBTs, causing the inverter to immediately shut off the output to protect these critical power devices, and preventing retry operations.
Additional Steps
Steps 1–2 are listed in Priority Fix.
- 3
Ensure acceleration and deceleration times (F002/F003/A092/A093) are not set too aggressively for the application's inertia.
- 4
Inspect the IGBT module (if accessible and by qualified personnel) for any signs of physical damage or overheating.
- 5
If external factors are ruled out, the IGBT driver circuit or the IGBT module itself may be faulty; contact Omron technical support.
