Why is my ATV630 drive noisy?

Issue:

Has a ATV630 drive that is noisy

Product Line:

ATV630

Environment:

Noise issues

Cause:

n/a

Resolution:

First question would be is the noise coming from an internal fan, inside the drive or is there excessive motor noise with the drive, running the motor?

If it is coming from the internal fan, could be some blockage keeping the fan from turning as it should? Could also be an issue with the fan itself?

If the problem is motor noise, then here are some suggestions:

Go to 5.2 menu and recheck all the motor parameters and make sure they match the motor nameplate.

Could reduce the switching frequency and make sure the noise reduction is turned on.

Be sure you are using shielded cables.

Always separate power cables and control cables.
