EMC Filtering of the Bassoon Servo Drive Controller
Elmo Motion Control
uses a proprietary FASSTechnolgy to control the power conversion of its drives. Our unique Fast And Soft Switching Technology significantly reduces the EMI typically created
by PWM drives. In most of the applications with Elmo drives no additional external means (such as filters) are required
to meet the EMC requirements.
The Bassoon Servo Drive Controller,
being a very compact, extremely high density “Direct to the Main” servo drive, is a “bit” more sensitive
to the application environment, such as wiring, grounding, etc. In most applications the Bassoon meets the EMC requirements.
However, in some extreme cases, when the drive is exposed to “tough” environmental conditions, an external filter
is recommended.
Below is a typical filter design that can be used in conjunction with the Bassoon
servo drive in applications requiring EMC filtering. Any first order filter which includes a common mode choke and differential capacitors should work. |
