• The transition from acceleration/deceleration time 1 to acceleration/deceleration time 4, may also be enabled by the external
terminals. The external terminal has priority over Pr. 01-23.
• It is used to give the smoothest transition between speed changes. The accel./decel. curve can adjust the S-curve of the
accel./decel. When it is enabled, the drive will have different accel./decel. curve by the accel./decel. time.
• The S-curve function is disabled when accel./decel. time is set to 0.
• When Pr.01-12, 01-14, 01-16, 01-18 ³ Pr.01-24 and Pr.01-25,
the Actual Accel. Time = Pr.01-12, 01-14, 01-16, 01-18 + (Pr.01-24 + Pr.01-25)/2
• When Pr.01-13, 01-15, 01-17, 01-19 ³ Pr.01-26 and Pr.01-27,
the Actual Decel. Time = Pr.01-13, 01-15, 01-17, 01-19 + (Pr.01-26 + Pr.01-27)/2
