Remarks
Standard pattern. Effective for preventing
the collapse of cargo
carried by lift or
conveyor for example.
Effective for the tension control of winding machine,
to prevent cutting the object to be wound, for
example.
Effective for lift
application because of
the shock less start and
stop.

(2) A131 Curve constant (swelling)
Large A131 value will result in a big swelling. A132 is the same concept as above.
(3) A150~a153 Curvature of EL-S-curve
When using EL-S-curve pattern, you can set the curvatures individually for acceleration
and deceleration. If all the curvatures are set to 50%, the EL-S-curve pattern will be
equivalent to the S-curve pattern.
