18. MR-J4W2-0303B6 SERVO AMPLIFIER
18 - 39
18.3.10 Grounding
WARNING
Ground the servo amplifier and servo motor securely.
To prevent an electric shock, always connect the noiseless grounding terminal
(marked
) 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)67303).
