b2-01
Zero speed level (DC
injection braking
starting frequency)
Used to set the frequency which
starts DC injection braking (the ini-
tial excitation for flux vector con-
trol) in units of 0.1 Hz when decel-
eration to stop is selected.

DCInj Start Freq
When b2-01 is less than E1-09,
E1-09 becomes the DC injection
braking starting frequency. Only
with flux vector control is b2-01
used.

rent as a percentage of the Inverter
rated current.

DCinj Current
The initial excitation current for
flux vector control depends on
