！ Warning
A deceleration circuit or shock absorber may be required.
When a driven object is operated at high speed or the load is heavy, a
cylinder's cushion will not be sufficient to absorb the shock. Install a
deceleration circuit to reduce the speed before cushioning, or install an
external shock absorber to relieve the shock. In this case, the rigidity of the
machinery should also be examined.
