Grounding

The ground connection of all relevant components must be made
with the largest possible cross-section, with a low impedance, over a
wide area and via a short connection to a conductive fastener with a
wide area. The shields have to be applied with a sufficiently large
contact area on both sides.
The shield of the AX8000 multi-axis servo system is connected via
the grounding hangers and hexagonal nuts, similar to DIN 6923 with
flange and serrations class 8 with the galvanized surface. These
components are included in the scope of supply of the AX8206 or
AX81x8 axis module.
Use of components of a higher EMC category
The AX8000 multi-axis servo system conforms to EMC category C3
for industrial areas with respect to conducted interference emis-
sions. If you wish to use components that conform to a higher cate-
gory, you can limit the conducted interference emissions using addi-
tional filters to the extent that the EMC category C2 for residential
and industrial areas is complied with.
Example drive system
In this chapter, the device connection is shown by the example of a
multi-axis drive system consisting of an AX8620 power supply mod-
ule and two AX8206 and AX8108 axis modules.
