WARNING
•
Gorund the servo amplifier and servo motor securely
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.
