Note1: * The table above shows output values of output shaft.
Note2: * The values in the table above are obtained when connected to HA-770 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, for specific environmental tolerances.
Note4: * Value after angular position of the HA-770 servo driver is corrected.
