4.2.2 EMI Protection
Electromagnetic interference (EMI) is an important concern for users of digital
servo control systems. EMI will cause control systems to behave in unexpected and
sometimes dangerous ways. Therefore, reducing EMI is of primary concern not only
for servo control manufacturers such as Lenze, but the user as well. Proper shielding,
grounding and installation practices are critical to EMI reduction.
4.2.3 Enclosure
The panel in which the PositionServo is mounted must be made of metal, and must be
grounded using the SPG method outlined in section 4.2.1.
Proper wire routing inside the panel is critical; power and logic leads must be routed in
different avenues inside the panel.
You must ensure that the panel contains sufficient clearance around the drive. Refer
to Section 3.2 suggested cooling air clearance.
