1) The table shows output values of the actuator.
2) All specifications are applicable for actuators mounted on an aluminum heat sink of size: 150 x 150 x 6(mm)
3) Values for saturated actuator temperature. Other values are for actuator temperature of 25°C.
4) The moment of inertia is the total value of the motor shaft and Harmonic Drive® gear converted to the output side.
5) All values are typical.
6) Quad encoder resolution is (motor shaft encoder resolution) x 4 x (gear ratio)
