E6581595E-555.3 Setting acceleration/deceleration time ：Automatic acceleration/deceleration ：Acceleration time 1 ：Deceleration time 1• Function1) For acceleration time 1  programs the time that it takes for the inverter output frequency to go from0Hz to maximum frequency .2) For deceleration time 1  programs the time that it takes for the inverter output frequency to gotfrom maximum frequency  to 0Hz.5.3.1 Automatic acceleration/decelerationThis automatically adjusts acceleration and deceleration time in line with load size. =* Adjusts the acceleration/deceleration time automatically within the range of 1/8 to 8 times as long as thetime set with the  or , depending on the current rating of the inverter. =* Automatically adjusts speed during acceleration only. During deceleration, speed is not adjustedautomatically but reduced at the rate set with .Outputfrequency (Hz)DecelerationtimeAccelerationtimeWhen load is smallTime[sec]0Shorten acceleration/deceleration timeDecelerationtimeAccelerationtimeWhen load is largeOutputfrequency (Hz)Time[sec]0Lengthen acceleration/deceleration timeSet  (automatic acceleration/deceleration) to  or .[Parameter setting]Title Function Adjustment range Default setting Automatic acceleration/deceleration0: Disabled (manual)1: Automatic2: Automatic (only at acceleration)0, When automatically setting acceleration/deceleration time, always change the acceleration/decelerationtime so that it conforms to the load. The acceleration/deceleration time changes constantly with loadfluctuations. For inverters that requires a fixed acceleration/deceleration time, use the manual settings(, ).efesotomasyon.com -Toshiba inverter,drive,servo,plc
