WARNING
(1) Connection diagram
The servo amplifier switches the power transistor on-off to supply power to the servo motor. Depending
on the wiring and ground cablerouting, 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).
24VDC
Ground the servo amplifier and servo motor securely.
To prevent an electric shock, always connect the earth terminal (E) of the servo
amplifier to the earth (E) of the control box (refer to (2) of this section for the fitting
method of the earth terminal).
