. If the operation command is removed, the inverter will perform base block (b.b)
based on the minimum base block time (07-18) and the motor will be stopped by DC
braking set by 07-07.
.The DC braking time (t
DCDB
) of Figure 4.3.60 is determined by the set value of
07-08 (DC Braking start time) and the frequency that operation command is
removed.

. If the over-current protection occurs in DC braking process, you can increase the
minimum b.b time (07-18) until the protection happens no longer.
. Please refer to Figure 4.3.60 to understand the function of DC braking to stop.

. If the operation command is removed, the inverter will perform base block and the
motor will be coasting to stop. Before the achievement of operation waiting time,
the inverter will not perform operation and the operation command will be ignored
if the operation is input.
. When the operation command is removed, the operation waiting time (T1) is
determined by the deceleration time (00-15,17, 22 or 24) and the output
frequency.
