Acc/Dec times can be set based on the time required to reach the next step frequency from the
existing operation frequency. To set the Acc/Dec time values based on the existing operation
frequency, set BAS-08 (acc/dec reference) in the Basic group to ‘1 (Delta Freq)’.

Mode
Set the parameter value to 1 (Delta Freq) to set Acc/Dec times based on
Maximum frequency.
Configuration Description
0 Max Freq Set the Acc/Dec time based on Maximum frequency.
1 Delta Freq Set the Acc/Dec time based on Operation frequency.
If Acc/Dec times are set to 5 seconds, and multiple frequency references are used
in the operation in 2 steps, at 10 Hz and 30 Hz, each acceleration stage will take 5
seconds (refer to the graph below).
