Optimisation of performance with respect to emission and immunity requires the additional EMC
measures:
Ensuring the necessary immunity in industrial uses can require use of an EMC suppressor circuit.

This table shows which additional EMC measures can be implemented to optimise the behaviour of
the equipment in the intended environment with regard to immunity.
The units are intended for industrial use only. If the devices are used in the home, in business or in
commerce or in a small business, appropriate measures must be taken to ensure that the emitted
interference is below the permitted limits!

NOTE
Capacitor C1:
If the ceramic capacitor C1 is used, malfunctions can occur in PWMntarget operating mode.
Use signal source with low internal resistance in PWMntarget operating mode.

NOTE
Capacitor C2:
If using the ceramic capacitor C2, a firmware update with the Motion Manager PC firmware may no
longer be possible.
Remove the C2 capacitor when updating the firmware.
