(f) Varistors 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.
