Select the acceleration/deceleration pattern according to the following table.
Use the following graphs to determine the curve factor.
• The S-shape pattern has a portion where acceleration/deceleration time is faster in the middle of the
curve.
• If the LAD cancel (LAC) function is allocated to a multi-function input terminal and that terminal turns
ON, the acceleration/deceleration pattern is ignored and the output frequency follows the reference
frequency instantaneously.

Description
The motor
accelerates/
decelerates linearly
until the set output
frequency value is
reached.
This pattern is
effective to prevent
the collapse of load
on an elevator,
conveyor, etc.
These patterns are effective for tension
control and roll-break prevention
applications for winding equipment etc.
This pattern, with a
linear portion in the
middle of the curve,
provides shockless
start/stop as with
the S-shape
pattern.
