The S shape has an intermediate section where acceleration/deceleration time is shortened.
If "46: LAC (LAD cancel)" is selected for a multi-function input and the input is turned ON, the
acceleration/deceleration pattern is ignored and the output frequency instantaneously follows
to the reference frequency.
EL-S shape Ratio
When the EL-S shape is used, various Curve Ratios (A150 to A153) can be set for
acceleration/deceleration.
If all settings are "50 [%]", the Inverter operates in the same manner as with the S shape.
