It collects the experience of Danaher Motion engineers who have solved many noise problems in the field. In our experience, common start up problems such as excessive audible noise, intermittent drive faults, and erratic torque perturbations usually result from EMI noise. Moreover, those problems can be avoided by following these eight simple guidelines.

1. Use high-quality cables
Manufacturers who produce high quality hardware generally produce high quality cables designed specifically for use with their servo systems. Experience has shown that customers who use high quality power and feedback cables have far fewer problems than customers who user lesser quality cables, or build their own cables.
