3.11 Grounding
WARNING
Ground the servo amplifier and servo motor securely.
To prevent an electric shock, always connect the protective earth (PE) terminal
(marked ) of the servo amplifier to the protective earth (PE) of the cabinet.
The servo amplifier switches the power transistor on-off to supply power to the servo motor. Depending on
the wiring and ground cable 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 always ground.
To conform to the EMC Directive, refer to "EMC Installation Guidelines".
Ensure to connect the
wire to the PE terminal
of the servo amplifier.
Do not connect the wire
directly to the grounding
of the cabinet.
