Note 1: The table shows typical output values of actuators.
Note 2: Values for saturated temperature under the conditions that the actuator is driven by an appropriate driver.
Note 3: All values are typical.
Note 4: Quad encoder resolutions are obtained by [motor encoder resolution] x 4 x [reduction ratio]
Note 5: Refer to the HA-800 manual for details.
Note 6: All parts, except the rotary sliding parts (oil seal) and connectors, are protected against solid bodies of
superior dimensions to 1mm, and against the water sprays.
