brake time at startup as set, as shown in Fig.6-12.
DC brake current at startup: 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 startup: It refers to the continuous DC brake time. If it is
set to 0, the inverter will be started directly without undergoing DC brake.

MD280 series inverter provides two types of speed-up/speed-down times,
0: Straight speed-up/speed-down
The output frequency increases or decreases along the straight line. It can
select speed-up/speed-down time via the multifunctional digital input
terminals
