b2-01
DC injection
braking starting
frequency
Used to set the frequency at which
DC injection braking starts in units
of Hz when b1-03 is set to 0 (decel-
eration to stop).
When b2-01 is less than E1-09, E1-
09 becomes the DC injection brak-
ing starting frequency.

braking time at
start
Used to set the time to perform DC
injection braking at start in units of
