6.3.3 Acceleration/Deceleration Time and S-curve Setting
Acceleration time indicates time required by the AC drive to accelerate from 0 Hz to acceleration/
deceleration time base frequency (F0-25).
Deceleration time indicates time required by the AC drive to decelerate from acceleration/
deceleration time base frequency (F0-25) to 0 Hz.

The AC drive provides totally four groups of acceleration/deceleration time for selection. You can
perform switchover by using a DI terminal.
● Group 1: F0-17, F0-18
● Group 2: F8-03, F8-04
● Group 3: F8-05, F8-06
● Group 4: F8-07, F8-08
For example, select DI7 and DI8 for switchover.
Related function parameters are set as follows:
