(2) Restart time of automatic reset (07-01)
. When 07-01 is set to 0, the automatic restart time interval is the smallest base block
time (07-18).
. When 07-01 <07-18, the auto-restart interval is set by 07-18.
. When 07-01> 07-18, the automatic restart interval is set by 07-01
. Refer to Figure 4.3.56 for setting automatical restart interval.

. If DC voltage is applied on the operating motor, the motor will produce braking torque,
which is DC braking. The parameters from 07-06 to 07-08 and 07-16 will regulate
these settings.
. When performing the speed search function, it is necessary to relieve the DC braking
firstly.
. DC braking function can be enabled by supplying DC current to the motor. This will
occur in DC braking time 07-16 before the start and in DC braking time 07-18 in
stopping.
. In response to the start point 07-16 of DC braking time, set the DC braking action
time when the motor is started. That can prevent the "windmill effect" due to the load
drives the motor, ensuring the stop of motor.
. If 07-16 is set to 0 (DC Injection Braking Time at Start), the inverter will start from the
