5.3.2 Stop Mode
You can set the stop mode of the AC drive in F6-10, decelerate to stop and coast to stop. The re-
lated function parameters are listed as follows:

F6-11: The AC drive starts DC injection braking when the running frequency decreases to the
value set in this parameter in the process of deceleration to stop.
If the rated motor current is less than or equal to 80% of the rated AC drive current, the base value
is the rated motor current.
If the rated motor current is greater than 80% of the rated AC drive current, the base value is 80%
of the rated AC drive current.

F6-13: It has the following two different base values.
F6-12: When the running frequency decreases to the value set in F6-11, the AC drive stops out-
put for a period of time and then starts DC injection braking. This prevents the occurrence of fault
such as overcurrent caused by direct DC injection braking at high speed.
5.3.3 Acceleration/Deceleration Time and S-curve Setting
Acceleration time indicates time required by the AC drive to accelerate from 0 Hz to accelerat-
ion/deceleration time base frequency (F0-25).
Deceleration time indicates time required by the AC drive to decelerate from acceleration/de-
celeration time base frequency (F0-25) to 0 Hz.

The AC drive provides totally four groups of acceleration/deceleration time for selection. You can per

form switchover by using a S terminal.
