DC brake initial frequency at stop: During the process of decelerating to
stop, when the running frequency at stop reaches this frequency, it will start
the process of DC brake at stop.
DC brake waiting time at stop: Prior to the beginning of DC brake at stop,
the inverter will terminate the output, and then start DC brake after this
delay time. It is used to prevent over current fault due to DC brake which
starts at the time of higher velocity.
DC brake current at stop: The DC brake quantity added shall be set
according to the percentage setting of the rated current of the inverter. The
higher the brake current is, more powerful the brake effect is.
DC brake time at stop: It refers to the continuous DC brake time. If this DC
brake time is set to 0, it indicates that there is no DC brake process, and
the inverter will stop according to the set process of decelerating to stop.
DC brake at stop function must be enabled by the external terminal DI.
Refer to “DC Brake at Stop Enable” function of input terminal in Group F2
for details.
The process of DC brake at stop is as shown in Fig.6-15:
