4.10 Setting Acceleration and Deceleration Times
4.10.1 Acc/Dec Time Based on Maximum Frequency
Acc/Dec time values can be set based on maximum frequency, not on inverter operation
frequency. To set Acc/Dec time values based on maximum frequency, set BAS- 08 (Acc/Dec
reference) in the Basic group to 0 (Max Freq).
Acceleration time set at the ACC (Acceleration time) code in the DRV group (DRV-03 in an LCD
keypad) refers to the time required for the inverter to reach the maximum frequency from a
stopped (0 Hz) state. Likewise, the value set at the Dec (deceleration time) code in the DRV group
(DRV-04 in an LCD keypad) refers to the time required to return to a stopped state (0 Hz) from the
maximum frequency.

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.
If, for 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).
