What does 6 Fault Code mean?

The intermediate circuit DC voltage is insufficient. This can occur if the input power is unstable.

• Missing phase in the input power supply
• Blown fuse in the power circuit
• Under voltage on the main circuit

1. 1

   Check the input power supply for all phases.

2. 2

   Inspect fuses in the main power circuit and replace if blown.

3. 3

   Verify the main circuit voltage is within the acceptable range.

4. 4

   Reset the VFD after verifying power supply.
