    Note1: * The table above shows output values of output shaft.
    Note2: * The values in the table above are obtained when connected to HA-720 servo driver.
    Note3: * The repeatability positioning precision and Absolute positioning accuracy repeatability
    are the values measured in an environment of 23 ±0.3°C in temperature, 50% RH in humidity
    and with output shaft facing upward in mounting direction.
    Please contact Harmonic Drive LLC, if you inquire to use with different environmental condition.
    Note4: * Value after angular position of the HA-720 servo driver is corrected.
