*1 Pushing force accuracy is LER10: ±30% (F.S.), LER30: ±25% (F.S.), LER50: ±20% (F.S.).
*2 The angular acceleration, angular deceleration and angular speed may fluctuate due to variations in the moment of inertia. Refer to the "Moment of Inertia—Angular Acceleration/Deceleration, Effective Torque—Angular Speed" graphs on pp. 406 and 407 for confirmation.
*3 The speed and force may change depending on the cable length, load, mounting conditions, etc. Furthermore, if the cable length exceeds 5 m, then the speed and force will decrease by up to 10% for each 5 m. (At 15 m: reduced by up to 20%)
*4 A reference value for correcting an error in reciprocal operation.
*5 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 from 45 to 2,000 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.)
*6 The power consumption (including the controller) is for when the actuator is operating.
*7 The standby power consumption when operating (including the controller) is for when the actuator is stopped in the set position during operation.
*8 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.
Table rotation angle range
External stopper: 180°
External stopper: 90°
*The figures show the origin position for each actuator.
*1 Range within which the table can move when it returns to origin. Make sure the workpiece mounted on the table does not interfere with the workpieces and equipment around the table.
*2 Position after return to origin. The position varies depending on whether there is an external stopper.
*3 Element in parentheses applies when the direction of return to origin has changed.

Mounting the workpiece to the electric rotary table
The load should be mounted to the product by screwing the screw into the female mounting thread. See the table below for appropriate tightening torque and screw length. If the threaded portion is too long, it can interfere with the body and cause a malfunction.
