Grounding
The servo amplifier supplies power to the servo motor by switching on and off a power transistor. Depending on the wiring and
ground wire routing, the servo amplifier may be affected by the switching noise (due to di/dt and dv/dt) of the transistor. To
prevent such a fault, refer to the following diagram and ground it.
For information on how to comply with the EMC Directive, refer to "EMC Installation Guidelines".
