Acceleration and deceleration pattern
(1) Selection of pattern
Pattern of acceleration and deceleration speed is possible to set up
corresponding to each system.
Select the pattern of acceleration and deceleration with A097 and A098.

Collapsing the cargo
such as the going up
and down machine,
conveyor it uses it for
prevention.
Cutting the tension control, rolled book such
as the volume collector machine it uses it for
prevention.
It is possible to set the pattern of both acceleration, deceleration.
(2) The curve constant (the swelling degree)
It makes the rough sketch reference and please decide the swelling degree.
There is the range which the midway adjustable-speed time becomes fast in the S character pattern.
