        1 When the power is turned off, or output current is turned off (non-excitation state), the actuator loses its thrust force or holding force. As such, it can no longer keep the
            the load in position or withstand an external force.
        2 Use the actuator at or below the following maximum speed in a low-temperature environment (0 to 0 10˚C DRS28 20m/s DRS28 :20mm/s

        3 The maximum thrust force is measured during constant-speed operation in horizontal operation with no load applied to the moving parts (screw shaft and joint). Thrust
            force varies with load mass and acceleration.
        4DRS2840% The maximum holding force at excitation is the value when the automatic current cutback function is ON (DRS28 : 40% DRS42 : 50%).

Note:

        1              When the power is turned off, or output current is turned off (non-excitation state), the actuator loses its thrust force or holding force. As such, it can no longer keep the
