Accel/Decel TimeH1-oo = 7 Acceleration Time Deceleration TimeClosed C1-03 C1-04n Using S-Curve Characteristics during Acceleration/DecelerationUsing S-curve characteristics to smooth acceleration and deceleration minimizes abrupt shockto the load. Set S-curve characteristic time during acceleration/deceleration at start andacceleration/deceleration at stop.Note: Setting S-curve characteristics will lengthen accel/decel times as follows:Accel Time = Selected Accel Time + (C2-01 + C2-02)/2Decel Time = Selected Decel Time + (C2-03 + C2-04)/2Setting ExampleFigure 4.13 illustrates S-curve characteristics switching between forward and reverse.C2-02C2-01C2-03 C2-04C2-02C2-01C2-03C2-04Forward RunCommandReverse RunCommandOutputFrequencyFigure 4.13 S-Curve Characteristicsu Drive Duty Mode and Carrier Frequency Selection: C6-01 andC6-02n Drive Duty Mode Selection: C6-01The drive has two different duty modes from which to select based on the load characteristics.The drive rated current, overload capacity, carrier frequency, and maximum output frequencywill change depending upon the duty mode selection. Use parameter C6-01 (Duty Cycle) toselect Heavy Duty (HD) or Normal Duty (ND) for the application. The default setting is ND.Refer to Specifications on page 187 for details about the rated current.HD and ND Mode SelectionsMode HD Rating ND Duty RatingC6-01 0 14.5 Basic OperationYASKAWA ELECTRIC TOEP C710606 25B YASKAWA AC Drive J1000 Installation & Start-Up Manual 934 Start-Up Programming& Operation
