(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 and TND20V-471K, manufactured by NIPPON
CHEMI-CON, are recommended. For detailed specification and usage of the varistors, refer to the
manufacturer catalog.
