Open output Immediate disconnection

What does 82 mean?

This fault occurs in 'VFC hoist' operating mode when two or all output phases to the motor are interrupted. It can also indicate a significant mismatch where the rated motor power is too small relative to the inverter's power. The inverter detects an open circuit condition on its output, leading to immediate disconnection.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Confirm that the rated motor power is correctly matched to the inverter's power rating, and update startup data if adjustments are made.

2. 4

   Perform a new startup procedure after checking connections and power ratings to re-evaluate the system.
