*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.

Precautions

Design/Selection

  • *If the operating conditions involve load fluctuations, ascending/descending movements, or changes in the frictional resistance, ensure that safety measures are in place to prevent injury to the operator or damage to the equipment. Failure to provide such measures could accelerate the operation speed, which may be hazardous to humans, machinery and other equipment.
  • *Power failure may result in a decrease in the pushing force; ensure that safety measures are in place to prevent injury to the operator or damage to the equipment. When the product is used for clamping, the clamping force could be decreased due to power failure, potentially creating a hazardous situation in which the workpiece is released.
  • *If the operating speed is set too fast and the moment of inertia is too large, the product could be damaged. Set appropriate product operating conditions in accordance with the model selection procedure.
  • *If more precise repeatability of the rotation angle is required, use the product with an external stopper (180° ±2°, 90° ±2°) or by directly stopping the workpiece using an external object utilizing the pushing operation.
  • *When using the electric rotary table with an external stopper, or by directly stopping the load externally, be sure to set to [Pushing operation]. Also, ensure that the workpiece is not impacted externally during the positioning operation or in the range of positioning operation.

Mounting

  • *Do not drop or hit the electric rotary table to avoid scratching and denting the mounting surfaces. Even slight deformation can cause the deterioration of accuracy and operation failure.
  • *When mounting the load, tighten the mounting screws within the specified torque range. Tightening the screws with a higher torque than recommended may cause malfunction, while tightening with a lower torque can cause displacement of the mounting position.
  • *When mounting the electric rotary table, tighten the mounting screws within the specified torque range. Tightening the screws with a higher torque than recommended may cause malfunction, while tightening with a lower torque can cause displacement of the mounting position.

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.
