What does 2 Fault Code mean?

The intermediate circuit DC voltage is too high. This can happen during deceleration or due to power supply issues.

• Static or transient over voltages in the input power supply
• Insufficient deceleration time
• Undersized brake chopper (if present)

Click steps to track your progress.

1. 1

   Check the input power supply for voltage spikes or transients.

2. 2

   Adjust deceleration time parameters if they are too short.

3. 3

   Verify the brake chopper (if used) is adequately sized.

4. 4

   Reset the VFD after addressing the cause.
