When an AC motor drive is installed in a noisy environment, radiated and/or conducted noise via

signal and power cables can interfere with the correct functioning, cause errors or even damage to

the drive. To prevent this, some AC motor drives have an enhanced noise resistance but the

results are limited and it is not economical. Therefore, an effective method would be finding the

cause of the noise and use the right solution to achieve "no emission, no transmission and no

reception of noise". All three solutions should be applied.

Ascertain whether the error is caused by noise.

Find the source of the noise and its transmission path.

Confirm the signal and the source of noise
