Preface
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.
Finding the Noise
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
Solutions
Grounding
Shielding
Filtering
