Pattern Curve Parameter (Curve Factor)
•Determine a curve factor with reference to the figures below.
•The S pattern has an intermediate section where acceleration/deceleration time is shortened.
•If LAD cancel (LAC) is selected for a multi-function input and that input is turned on, the
acceleration/deceleration pattern is ignored, and the output frequency instantaneously follows the
reference frequency.
EL-S Curve Ratio
If the EL-S pattern is used, you can set a curve ratio (A151 to A153) individually for acceleration and
deceleration.
If all settings are "50 (%)", the Inverter operates in the same manner as with the S curve.
