Precautions when driving

• 1. Make sure that the static and dynamic load acting on the main body is below the basic capacity, allowable input shaft torque, and allowable overhang load. (For details, see the selection method here.)
• 2. If necessary, install a shock absorber to prevent direct impact on the main body.
• 3. Gear motors, servo motors, etc. can be used as the drive source. However, since the main unit is extremely efficient, it will reverse depending on the load. Be sure to use a brake or a motor with a brake to prevent coasting and reverse rotation due to the load. In addition, use a brake with a braking torque of 150% or more and with good response.
• 4. If the average no-load operating torque accounts for 25% or more of the required input torque, torque fluctuations due to the chain's unique meshing action will become significant. To ensure smooth operation, select a torque that is 1.5 times the average no-load operating torque.
• 5. When you first start using the product, the average no-load operating torque may be high, but this is just the initial settling in and will gradually stabilize, so continue using it as is.
• 6. Percentage duty cycle without motor (%ED) [operating time ÷ (operating time + pause time)] depends on the motor and device input, and is therefore based on the capacity of the drive source.
• 7. When using this product in personnel transport equipment, be sure to install safety protection devices on the equipment side.
  There is a risk of personal injury or damage to the device due to runaway.
• 8. When using in a lifting device, be sure to install a safety device on the device to prevent it from falling.
  There is a risk of personal injury or damage to the equipment due to the lifting body falling.
• 9. When using a chain for a suspension system, be sure to install a safety device in case the chain breaks. In addition, install a safety fence and never enter under the suspended object.
• 10. Even when using a servo motor and needing to stop it in an emergency, do not use the motor's built-in mechanical brake. Be sure to use control logic that activates the mechanical brake after deceleration by the dynamic brake. For details, refer to the motor manufacturer's instruction manual.
