LERH50K-1-S56P5
LER Series Electric Rotary Table, Continuous Rotation Specification external appearance
LER: basic type / LERH: high-precision type
Table rotation angle range
*1 Range within which the table can move. Make sure the workpiece mounted on the table does not interfere with the workpieces and equipment around the table.
*2 The sensor detection range is recognized as the origin. When detecting the sensor, the table rotates in the reverse direction within the sensor detection range.

*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 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.
*9 The angle displayed on the monitor is automatically reset to 0° every 360°. To set an angle (position), use the "Relative" movement mode. If an angle of 360° or more is set using the "Absolute" movement mode, the correct operation cannot be performed.

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.
