 This function does not require external terminal switching function, it will switch the accel. / decel.
time automatically by Pr. 01-23 setting. If the external terminal is set, it will be prior to Pr. 01-23.
 When using this function, please set S-curve acceleration time as 0 if 4
th
acceleration time is set
too short.

Pr. 01-45 = 1: 0.0~250.0 sec.
 This parameter is used to set slow start when the drive begins to accelerate at start. The accel. /
decel. curve can adjust the S-curve accel. / decel by setting parameter value. 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  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  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
