Short circuit

What does 16 mean?

A direct short circuit exists in the motor windings or the motor wiring connected to the frequency converter's output terminals. This is a critical fault that can cause immediate and severe damage to the frequency converter's output stage if power is not removed quickly. Continued operation is highly dangerous.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Using a multimeter, check the resistance between motor phases and between each phase and ground to pinpoint the short circuit location.

2. 4

   Repair or replace the short-circuited motor or wiring before reapplying power.
