Sensor holder L Proximity sensor assembly Series LER Electric Rotary Table/ Specific Product Precautions 1 Be sure to read before handling. Refer to “Handling Precautions for SMC Products” (M-E03-3) for Safety Instructions and the Operation Manual for Electric Actuator Precautions. Please download it via our website, http://www.smcworld.com Through-hole mounting Warning Mounting 1. 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. 2. 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. Warning Design/Selection 1. 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. 2. If more precise repeatability of the rotation angle is required, use the product with an external stopper, with repeatability of ±0.01° (180° and 90° with adjustment of ±2°) or by directly stopping the workpiece using an external object utilizing the pushing operation. 3. When using the electric rotary table with an external stopper, or by directly stopping the load externally, ensure that the [Pushing operation] is utilized. Also, ensure that the workpiece is not impacted externally during the positioning operation or in the range of positioning operation. Caution 3. 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, whilst the tightening with a lower torque can cause the displacement of the mounting position. 1. 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. 2. 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, whilst the tightening with a lower torque can cause the displacement of the mounting position. Mounting the workpiece to the electric rotary table The load should be mounted with the torque specified in the following table by screwing the bolt into the mounting female thread. If long threads are used, they can interfere with the body and cause a malfunction, etc. Warning Mounting Model Bolt Thread length [mm] Max. tightening torque [N・m] LER�ｮ10 M4 x 0.7 6 1.4 LER�ｮ30 M5 x 0.8 8 3.0 LER�ｮ50 M6 x 1 10 5.0 Model Bolt Max. tightening torque [N・m] LER�ｮ10 M5 x 0.8 3.0 LER�ｮ30 M6 x 1 5.0 LER�ｮ50 M8 x 1.25 12.0 Model L [mm] (Initial setting) Cable entry: Basic type/Entry on the left side (Between the sensor holder end face and proximity sensor end face) LER�ｮ10-1 31/31 LER�ｮ30-1 42/42 LER�ｮ50-1 51.5/51.5 Body mounting/Bottom 4. The mounting face has holes and slots for positioning. Use them for accurate positioning of the electric rotary table if required. 5. If it is necessary to operate the electric rotary table when it is not energized, use the manual override screws. When it is necessary to operate the product by the manual override screws, check the position of the manual override screws of the product, and leave necessary space. Do not apply excessive torque to the manual override screws. This may lead to damage and malfunction. 6. The 360° type proximity sensor for return to origin can be changed ±30°. When changing the position of the proximity sensor for return to origin, tighten the screws with a tightening torque of 0.6±0.1 [N・m].
