15.3.8 Grounding
WARNING
Ground the servo amplifier and the servo motor securely.
To prevent electric shock, be sure to connect the noiseless grounding (
) terminal
of the servo amplifier to the grounding terminal 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 the EMC Installation Guidelines (IB(NA)67310).
