DC injection braking current at start is a percentage value of inverter
’
s rated current. There is no DC injection braking when
the braking time is 0.00s.

After receiving the stopping command, the inverter reduces its output frequency according to Dec time and then start to DC
injection braking after the output frequency reaching the initial frequency of braking at stop as i n P2.06 .
P2.08 refers to the set of DC injection braking current at stop which is the percentage value of inverter
’
s rated current .There
is no DC injection braking when the braking time is 0.0, as shown in Fig.4-12 .
