* The setting range is 0 or 1 for flux vector control and open-loop vector control 2.
Deceleration to Stop
If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 0, the motor deceler-
ates to a stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration Time
1))
If the output frequency when decelerating to a stop falls below b2-01, the DC injection brake will be applied
using the DC current set in b2-02 only for the time set in b2-04.
For deceleration time settings, refer to page 6-16 Setting Acceleration and Deceleration Times .

Used to set the time to perform DC injec-
tion braking at start in units of 1 second.
Used to stop coasting motor and restart it.
When the set value is 0, DC injection
braking at start is not performed.
