Acc/Dec Time Switch Frequency
You can set a switch frequency (Ad.60) to switch between 2 different Accel times and 2 different
Decel times. Parameters bA.70 (step accel time1) and bA.71 (step decel time1) are in effect below
the switch frequency. Parameters ACC (Accel time) and Dec (Decel time) are in effect above the
switch frequency.

Description
Ad.60
Acc/Dec time
transition
frequency
Set the Acc/Dec transition frequency (Ad.60). Acc/Dec gradients
configured at bA.70 and bA.71 will be used when the inverter’s
operating frequency is at or below the switch frequency.
When the operating frequency exceeds the switch frequency, Acc/Dec
gradients configured at ACC and dEC will be used.
If you configure any of the P1–P5 digital input terminals for multi-step
Acc/Dec gradients (XCEL-L, XCEL-M, XCEL-H), Ad.60 Acc/Dec switch
frequency will not operate.
