In case you are running several servo drives behind a contactor, please use an uni-directional TVS diode on
each drive because of the inductances of the wiring.
1.2.2.1.1.1.1.1 Functional Earth
Functional Earth (FE) and the Ground (GND) of the electronic boards are electrically isolated.
The blank bottom side of the heatsink has a flat conductive surface and can be used as a connection for
Functional Earth (FE).
For a better EMI shielding around the electronic boards, it is necessary to electrically connect the
conductive surfaces (marked blue in the following picture) to the chassis of the motor or the robot.
Important
Please ensure that the chassis is properly grounded.
