5.10 DC INJECTION BRAKING
C . H 3 - 0 5 : Multi-function Analog Input
(Term. 16)
The multi-function analog input at terminal 16 may be configured to allow analog control of
the amount of DC injection braking current (from 0% to 100% of the current level set in
b 2 - 0 2 ), which directly controls the amount of DC injection voltage applied to the motor.

D . H 1 - 0 1 thru H 1 - 0 6 : Multi-function Inputs
Any multi-function input terminal can be utilized
to control DC injection braking. When used, DC
injection current will be applied until the input is
removed, provided that the drive output
frequency is below the DC Braking Start
Frequency ( b 2 - 0 1 ) .
EXAMPLE:
H 1 - 0 6 = 60
