Page 11: Electric Actuators / Slider Type Common Precautions
Electric actuators / Slider type Common precautions Design Warning 1. When mounting it vertically, at an angle, or in other situations where there is a height difference, install safety measures from the outside. (Latches, Movable bolts, Fall prevention devices, etc.) ・Design the structure so that the human body does not come into direct contact with the driven object or moving parts of the actuator. -
Page 12: Handling
Handling Warning 1. Do not allow the table (slider) to hit the end of stroke. If an incorrect input instruction is given, such as using it outside the specification range or changing the driver setting/origin position to give an operation instruction outside the actual stroke, the table (slider) can conflict. - Page 13 8. When mounting the actuator, use bolts with adequate size and tighten them with adequate torque. Tightening the screws with a higher torque than the maximum may cause malfunction, whilst tightening with a lower torque can cause the displacement of the mounting position or fall. Side support mounting Side support Mounting number: N...
- Page 14 9. Do not operate by fixing the table and moving the actuator body. 10. Vibration may occur during operation, this could be caused by the operating conditions. If it occurs, adjust response value of autotuning of driver to be lower. During the autotuning noise may occur, the noise will stop when the tuning is complete.
