4.3.6.1
EMC-compliant mounting of the Motion Controller with motherboard
The setup in Fig. 34 shows the assembly of a Motion Controller with motherboard. Each of
the cable shields is connected to earth potential with low impedance using a shield clamp.
Metallisations on screw connections on the PCB must also be connected to earth potential
with low impedance (e.g., conductive base plate).

4.3.6.2
PWM filter (motor-side)
Measures are provided in the device that come close to the effect of a PWM filter. Thus, an
external PWM filter is only necessary in exceptional cases.
4.3.6.3
Emission-reducing, ferrite-based filters (motor side)
These filters can be found in similar form and mode of action on the motherboards. The fil-
ters reduce the rise time of the motor voltage/current and thereby reduce the high-fre-
quency coupling currents on the shield.
