Unnecessary at some output frequencies. Contact the resonator manufacturer. 2. Put them as near the IC as possible. When attached at a distance, these parts lose effect. 3. The optimum value depends on the motor specification (moment of inertia including load, torque constant, standard rotation number). Hitachi America, Ltd. Hitachi Plaza * 2G00 Sierra Point Pkwy.
