Series LER Electric Rotary Table/ Specific Product Precautions 2 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 1. The high precision type bearing is assembled by pressing into position. It is not possible to disassemble it. Danger Maintenance 1. When an external guide is used, connect it in such a way that no impact or load is applied to it. Use a free moving connector (such as a coupling). 2. INP output signal 1) Positioning operation When the product comes within the set range by step data [In position], the INP output signal will turn on. Initial value: Set to [0.50] or higher. 2) Pushing operation When the effective force exceeds the [Trigger LV] value (including thrust during operation), the INP output signal will turn on. The [Trigger LV] should be set between 40% and [Pushing force]. a) To ensure that the clamping and external stop is achieved by [Pushing force], it is recommended that the [Trigger LV] be set to the same value as the [Pushing force]. b) When the [Pushing force] and [Trigger LV] are set less than the specified range, the INP output signal will turn on from the pushing start position. 3. When the workpiece is to be stopped by the electric rotary actuator with an external stopper or directly by an external object, utilize the “pushing operation”. Do not stop the table with an external stopper or external object by using in the range of the “positioning operation mode”. If the product is used in the positioning operation mode, there may be galling or other problems when the product/workpiece comes into contact with the external stopper or external object. 4. When the table is stopped by the pushing operation mode (stopping/clamping), set the product to a position of at least 1° away from the workpiece. (This position is referred to as the pushing start position.) If the pushing start position (stopping or clamping) is set to the same position as the external stop position, the following alarms may be generated and operation may become unstable. a. “Posn failed” alarm is generated. It is not possible to reach the pushing start position within the target time. b. “Pushing ALM” alarm is generated. The product is pushed back from a pushing start position after starting to push. c. “Deviation over flow” alarm is generated. Displacement exceeding the specified value is generated at the pushing start position. 5.There is no backlash effect when the product is stopped externally by pushing operation. For the return to origin, the origin position is set by the pushing operation. 6. For the specification with an external stopper, an angle adjustment bolt is provided as standard. The rotation angle adjustment range is ±2° from the angle rotation end. If the angle adjustment range is exceeded, the rotation angle may change due to insufficient strength of the external stopper. One revolution of the adjustment bolt is approximately equal to 1° of rotation. 7. When mounting the product, keep a 40 mm or longer diameter for bends in the motor cable.
