Configuring Acc/Dec Time Switch Frequency
You can switch between two different sets of Acc/Dec times (Acc/Dec gradients) by configuring the
switch frequency without configuring the multi-function terminals.

Acc/Dec Time Switch Frequency Setting Details
Code Description
bA.69
Xcel Change Fr
When the Acc/Dec switch frequency (bA.69, Xcel Change Fr) is set and the inverter
operation is at or below the set frequency, it will use the accel and decel times set
in parameters bA.70 and 71. If the operation frequency is above the switch
frequency, it will use the accel and decal times set in parameters ACC and dEC
codes.
If you configure the P1
–
P5 multi-function input terminals for multi-step Acc/Dec
gradients (XCEL-L, XCEL-M, XCEL-H), the inverter will operate based on the
Acc/Dec inputs at the terminals instead of the Acc/Dec switch frequency
configurations.
Acc/Dec Pattern Configuration
Acc/Dec gradient level patterns can be configured to enhance and smooth the inverter’s
acceleration and deceleration curves. The linear pattern features a linear increase or decrease to the
output frequency, at a fixed rate. With an S-curve pattern, a smoother and more gradual increase or
decrease of output frequency is performed. S-curve gradient level can be adjusted using codes Ad.
