6. Description of Parameters
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.
Figure 6-35 Acceleration/Deceleration time
The AC drive provides totally four groups of acceleration/deceleration time for selection. You can
perform switchover by using a DI terminal.
