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 decel-
erates 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 6-23 Setting Acceleration and Deceleration Times.
The operation after starting or stopping depends on the setting of b1-05 when flux vector control is selected
(A1-02 = 3).
