(f) Varistor for input power supply (recommended)
Varistors are effective to prevent exogenous noise and lightning surge from entering the servo
amplifier. When using a varistor, connect it between each phase of the input power supply of the
equipment. For varistors, the TND20V-431K, TND20V-471K and TND20V-102K, manufactured by
NIPPON CHEMI-CON, are recommended. For detailed specification and usage of the varistors,
refer to the manufacturer catalog.
