When the stop command is executed, please choose the stop mode. There are four
types of stop mode in total, but the DC brake to stop and the coast to stop with timer
can not be used under SV mode.
(1) 07-09=0:
‧ Deceleration to stop based on the setting of 07-09. When the operation command is
removed, the motor will decelerate to the minimum output frequency 01-08(Fmin)，
and then stop.
‧ Deceleration rate is depended on the deceleration time (factory default: 00-15). When
the output frequency has fallen to DC braking initiation frequency (07-06) or the
minimum output frequency (01-08), taking the greater setting value, the DC braking is
enabled and the motor stops.

(2)07-09=1:
. If the operation command is removed, the inverter will be closed, and the motor
will be coasting to stop based on the friction deceleration speed of the driving
system.
. After the operation command is removed, the follow-up operation command will
be ignored until the end of the minimum base block time (07-18).
. Please refer to Figure 4.3.59.
. In SLV mode (00-00 = 2), the next time start after the free operation will enable the
speed search function automatically. If the motor is stopped by mechanical
braking after the device operation command is removed, please modify the
parameter 07-26 to 1 (valid) (parameter 07-26 is only effected in version 1.3 or
later).
