Chapter 7 Basic Functions
You can change the Acc/Dec slope without using the multi-function terminal. The inverter operates at the slope set at
BAS-70, 71 below the Acc/Dec switching frequency set at ADV-60 of the operating frequency. However, if the operating
frequency rises over the Acc/Dec switching frequency, the inverter runs at the Acc/Dec slope set at DRV-03 and 04.
If you set and input the function of the multi-function input terminal at sequential Acc/Dec (Xcel-L, Xcel-M[HZ]), the
inverter runs by Acc/Dec input regardless of the Acc/Dec switching frequency.

This sets the pattern of the Acc/Dec slope. There are 5 patterns, which have the following functions.
Type Function
0 Linear The output frequency is constant and increases or decreases linearly.
1 S-curve
Frequency
FX
BAS-70
DRV-03
DRV-04
Used for applications requiring smooth Acc/Dec such as lift load and elevator
door. The curve rate of S-curve can be adjusted by using the functions of
03~06.
Caution
ADV-60
BAS-71
Be careful when you set the Acc/Dec pattern at S-curve because it gets longer
than the set Acc/Dec time. For actual Acc/Dec time, see Page 7-21.
