Overcurrent Protection During Deceleration

What does E02. mean?

This fault indicates an excessive current flow through the inverter during motor deceleration. Common causes include overly rapid deceleration settings, the application of mechanical brakes during deceleration, or high inertia loads. The inverter trips when the current exceeds roughly 200% of its rated output to safeguard its internal power circuitry.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Thoroughly inspect the motor and output wiring for any direct short-circuits.

2. 4

   Check for regenerative braking function (b095) settings and consider using external braking resistors if the load has high inertia.
