Setting Acceleration and Deceleration Times
Acc/Dec Time Based on Maximum Frequency
Acc/Dec times are based on maximum frequency (bA.08 set to 0 (MaxFreq)), not on inverter
operating frequency. Acceleration time set at ACC refers to the time required for the inverter to
reach the maximum frequency from a stopped (0 Hz) state. Likewise, deceleration time set at dEC
refers to the time required to decelerate from the maximum frequency to a stopped state (0 Hz).

Acc/Dec Time Based on Maximum Frequency – Setting Details
Code and
Features
Description
bA.08
Acc/Dec
reference
frequency
Set bA.08 to 0 (Max Freq) to setup Acc/Dec time based on maximum
frequency.
Configuration
Function
0
Max Freq
Set the Acc/Dec time based on maximum
frequency.
1
Delta Freq
Set the Acc/Dec time based on operating
frequency.
Example: maximum frequency is 60.00 Hz, the Acc/Dec times are set to
5 seconds. With a frequency reference of 30 Hz, the time required to
reach 30 Hz is 2.5 seconds.
bA.09
Time scale
Set the time scale for all time-related values. Set to 0 (0.01sec) when
more precise Acc/Dec times are required. Set to 2 (1sec) when the time
display and setting require less precision or need to be extended
above 60.00 secs.
Configuration
Function
0
0.01sec
Sets 0.01 second as the minimum unit.
1
0.1sec
Sets 0.1 second as the minimum unit.
2
1sec
Sets 1 second as the minimum unit.
