Chapter 6 Description of Function Codes
Acceleration time indicates the time required by the AC drive to accelerate from 0Hz to"Acc-
eleration/Deceleration base frequency" (F00.15), that is, t1 in Figure 6-1.
Deceleration time indicates the time required by the AC drive to decelerate from"Accelertion/-
Deceleration base frequency" (F00.15) to 0Hz, that is, t2 in Figure 6-1.

Fig.6-1 Acceleration/Deceleration time
When the set frequency is equal to the reference frequency of acceleration and deceleration,
the actual acceleration and deceleration time is consistent with the set acceleration and
deceleration time.
When the set frequency is less than the reference frequency of acceleration and decelerat-
ion, the actual acceleration time is less than the set acceleration and deceleration time.
Actual acceleration and deceleration time = set acceleration and deceleration time * (set
frequency / acceleration and deceleration reference frequency)
The provides totally four groups of acceleration/deceleration time for selection. You can perf-
orm switchover by using a DI
terminal.
Group 1: F00.12, F00.13 Group 2: F09.00, F09.01
Group 3: F09.02, F09.03 Group 4: F09.04, F09.05

Note:
When modifying this function parameter, the decimal places of all frequency-related
parameters will change, and the corresponding frequency value will also change. Special
attention should be paid during use.
