5.1.2 DRV-03, DRV-04 Acceleration and Deceleration Times
5.1.2.1 Acc/Dec Time Based on Maximum Frequency
Acc/Dec times are based on maximum frequency (BAS-08 set to ‘0, MaxFreq’). Acceleration time set at
DRV-03 (Acceleration time) refers to the time required for the inverter to reach the maximum frequency
from a stopped (0 Hz) state. Likewise, deceleration time set at DRV-04 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
Description
BAS-08
Ramp T Mode
Set the parameter value to 0 (Max Freq) to setup Acc/Dec time 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 operating frequency.
Example: Maximum frequency is 60.00 Hz, the Acc/Dec times are set to 5
seconds, and the frequency reference for operation is set at 30 Hz (half of
60 Hz), the time required to reach 30 Hz therefore is 2.5 seconds (half of 5
seconds).
