Note 1: The table shows output values of the actuator.
Note 2: All specifications are applicable for actuators mounted on an aluminum heat sink of size: 150 x 150 x
6(mm).
Note 3: Values indicated by an asterisk (*) are those for the saturated temperature rise. Other values indicate
the temperature at 20ºC. All values are typical.
Note 4: The moment of inertia is the total value of the motor shaft and gear moment of inertia values converted
to the output side.
Note 5: Quad encoder resolution is (motor shaft encoder resolution when multiplied by 4) x (gear ratio).
