• 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.
