EMI Filter Installation
All electronic equipment (including servo drive) generates high or low frequency noise
during operation and interfere the peripheral equipments via conduction or radiation. With
EMI Filter and the correct installation, much interference can be eliminated. It is suggested
to use Delta’s EMI Filter to suppress the interference better.
When installing servo drive and EMI Filter, please follow the instructions of the user manual
and make sure it meets the following specification.
1. EN61000-6-4 (2001)
2. EN61800-3 (2004) PDS of category C2
3. EN55011+A2 (2007) Class A Group 1
General Precaution
In order to ensure the best performance of EMI Filter, apart from the instructions of servo
drive installation and wiring, please follow the precautions mention below:
1. The servo drive and EMI Filter should be installed on the same metal plate.
2. When installing servo drive and EMI Filter, the servo drive should be installed above
the EMI Filter.
3. The wiring should be as short as possible.
4. The metal plate should be well grounded.
5. The metal cover of the servo drive and EMI Filter or grounding should be firmly fixed
on the metal plate. Also, the contact area should be as large as possible.
