Make sure a workpiece mounted on the table does not interfere with the workpieces and facilities around the table. Note 2) The sensor detection range is recognized as origin. When detecting the sensor, the table rotates in the reverse direction within the sensor detection range. Note 1) Pushing force accuracy is LER10: ±30% (F.S.), LER30: ±25% (F.S.), LER50: ±20% (F.S.). Note 2) The angular acceleration, angular deceleration and angular speed may fluctuate due to variations in the inertia moment. Refer to page 3 “Moment of Inertia.Angular Acceleration/Deceleration, Effective Torque.Angular Speed” graphs for confirmation. Note 3) The speed and force may change depending on the cable length, load and mounting conditions. Furthermore, if the cable length exceeds 5 m, then it will decrease by up to 10% for each 5 m. (At 15 m: Reduced by up to 20%) Note 4) Impact resistance: No malfunction occurred when the slide table 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 5) The power consumption (including the controller) is for when the actuator is operating. Note 6) The standby power consumption when operating (including the controller) is for when the actuator is stopped in the set position during operation. Note 7) The maximum instantaneous power consumption (including the controller) is for when the actuator is operating. This value can be used for the selection of the power supply. Note 8) The angle displayed on the monitor is automatically reset to 0° every 360°. To set an angle (position), use the INC (relative) operation method. If an angle of 360° or more is set using the ABS (absolute) operation method, the correct operation cannot be performed. 6 Electric Rotary Table Series LER Continuous Rotation Specification A
