The DC band-tape brake/brake injection current means the brake current outputted at the time of inverter DC
band-type brake/brake. Its set value is the percentage with respect to the rated current.

Running time
F0.4.48 Restart after power-off
Setting range: 0, 1
Factory default: 0
It is mainly for the trigger starting modes including “panel control, bus control and three-line control”. If the
function of restart after power-off is set to be effective, when the inverter is powered off, the running
command/status before power-off will be automatically saved, and it will automatically restore to the running
status before power-off after the waiting time after power-on again.
In case of the restart after power-off, it will resume running in the mode of restart at detected speed.
F0.4.49 Restart delay time
Setting range: 0.1~10.0Sec.
Factory default: 0.5
It means the time of waiting status before the inverter automatically executes the function of restart after
power-off.
F0.4.50 Direction change delay
time
Setting range: 0.00~5.00Sec.
Factory default: 0.00
The forward and reverse transition dead time is used to set the waiting time for the motor to shift from FWD
to REV or from REV to FWD. This function is used to overcome reversal current compact caused by
mechanical dead zone, as shown in Figure 7-21.
