F0.4.43 Start delay
Setting range:
0.00~10.00Sec.
Factory default: 0.0
Start delay means the waiting time before the inverter starts after receiving the running command.
F0.4.44 DC band-type brake
control
Setting range: 0000~0001 Factory default: 0
_ _ _ X : DC band-type brake control
The DC band-type brake means to lead DC current into the motor rotor so as to generate braking torque. The
DC band-type braking function cannot be used when synchronous motor is driven.
When both the set value and the actual speed of the motor has decreased below [F0.4.45], the inverter will
stop generating sine current but will inject direct current to the motor, and the current value is to be set by the
parameter [F0.4.47]. When the given speed or the motor speed has surpassed the parameter [F0.4.45], the
inverter will stop DC power supply and restore to the normal running status.
If it is started, the permission signal will be disconnected, and the DC band-type brake will be void.
F0.4.45 DC injection brake
application frequency
Setting range: 0.0Hz~[F0.1.21] Factory default: 2.00
In the deceleration and stop process of the inverter, when the output frequency is lower than the DC
band-type brake/brake start frequency/speed, the DC band-type brake/brake function will be started.
F0.4.46 DC brake action time Setting range: 0.00~10.00Sec. Factory default: 0.0
F0.4.47 DC injection brake
current level
Setting range: 0.0~100% Factory default: 50.0
The DC brake time is the duration of the output DC braking current. If it is selected that the external terminal
stop DC braking is effective, the parameter of DC braking action time will be void.

Figure 7-19 DC band-type brake sketch
¾ Injecting current to the moor may lead over-temperature of the motor. In the circumstances
where long-time DC band-type brake is needed, forced air-cooling motor should be used.
During the long time of band-type braking, if there is constant load in the motor band-type
brake, DC band-type brake will not guarantee that the motor shaft will not rotate.
