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 6-20 Setting Acceleration and Deceleration Times.

Coast to Stop
If
the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 1, the Inverter output
voltage
is interrupted. The motor coasts to a stop at the deceleration rate that counterbalances damage to the
machine
and inertia including the load.

INFO
After the stop command is input, run commands are ignored until the Minimum Baseblock Time (L2-03) has
elapsed.
