Note 2) The maximum value of the horizontal work load. An external guide is necessary to support the load. The actual work load changes according to the condition of the external guide. Please confirm using actual device. Note 3) The force setting range for the pushing operation (Speed control mode, Torque control mode). The pushing force changes according to the set value. Set it with reference to “Force Conversion Graph” on page 68. Note 4) The allowable collision speed for the pushing operation. Note 5) Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and a perpendicular direction to the lead screw. (Test was performed with the actuator in the initial state.) Vibration resistance: No malfunction occurred in a test ranging between 45 to 2000 Hz. Test was performed in both an axial direction and a perpendicular direction to the lead screw. (Test was performed with the actuator in the initial state.) Note 6) Each value is a guide. Use such value to select a motor capacity. Lead [mm] (including pulley ratio) Shaft length [mm] Thread size [mm] Actuation unit weight [kg] (.
