Note1: * The table above shows output values of output shaft.
Note2: * The values in the table above are obtained when connected to HA-730
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 ask Harmonic Drive Systems, if
you inquire use with different environmental condition.
Note4: * Value after angular position of the HA-730 servo driver is corrected. |
