1. Reduction ratio is to be calculated by the formula in the previous page, using R value in this table.
2. The maximum allowable value at the input rotation speed of 2000r/min
3. The maximum torque when starting and stopping.
4. The maximum torque when it receives shock.
5. The maximum average input speed.
6. The maximum input speed.
7. The life time at the input rotation speed of 2000 r/min and nominal output torque.
