4.1.3.3 Acceleration/Deceleration Time
The acceleration time indicates the time required for the AC drive to accelerate from 0 Hz to F0-25
(acceleration/deceleration base frequency). The deceleration time indicates the time required for the
AC drive to decelerate from F0-25 (acceleration/deceleration base frequency) to 0 Hz.
Figure 4-32 Acceleration/Deceleration time
The AC drive provides totally four groups of acceleration/deceleration time, which can be selected by
using a DI terminal (assigned with function 18/19). The acceleration/deceleration time is defined by the
following parameters:
Group 1: F0-17, F0-18
Group 2: F8-03, F8-04
Group 3: F8-05, F8-06
