Amplitude Characteristics (60 Hz) The above characteristic curves indicate the relation between half-amplitude and cycle speed, given sine wave motion at the rated load level.
The above indicates the amplitude characteristics given a 60 Hz power supply. Characteristics with a 50 Hz power supply will be
about 5/6 of indicated values.
The above characteristics do not include the frame or load cell characteristics. Compensate for the in uence of these factors to
AF-4 determine actual amplitude characteristics.
QF-10B/AF-10B 25 mm stroke The indicated characteristics values were calculated based on typical characteristics of the servo valve being used, which may result
QF-20B/AF-20B 50 mm stroke in a difference of about 10 % on the frequency axis.
There may be limitations on testing frequencies, depending on jig, sample, or other characteristics.
