Line Filtering - Advanced Digital SimpleServo SS504 User Manual

Figure 6. Wiring guidelines
Enclosure
The panel in which the servo is mounted must be made of metal, and must be grounded using the
SPG method outlined above.
Proper wire routing inside the panel is critical; power and logic leads must be routed in different
avenues inside the panel .
If you use drives that output over 8 amps, you must ensure that the panel contains sufficient clearance
above and below for the cooling fan to circulate air. Refer to Figure 3 for minimum suggested cooling
air clearance.

INE FILTERING
In addition to EMI/RFI safeguards inherent in the SimpleServo design, external filtering may be
required. High frequency energy can be coupled between the circuits via radiation or conduction. The
AC power wiring is one of the most important paths for both types of coupling mechanisms. There are
many AC line filter manufacturers whose filters can be successively integrated. Advanced Digital
recommends Schaffner filters based on our test results.
The following table shows a typical filter selection for SimpleServo drives.
