Warning
A deceleration circuit or shock absorber may be required.
When a driven object is operated at high speed or the load is heavy, the cushioning of
the cylinder 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.
