2.8 DC INJECTION BRAKING Continued
C. Sn-19: Multi-function Analog Data 07 : DC Injection Braking
Input (Term. 16) Current Adjust
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
Cn-11), which directly controls the amount of DC injection voltage applied to the motor.
D. Sn-15 thru Sn-18: Multi-function Data 60 : DC Injection Braking
Inputs (Term. 5 thru 8) Command
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 GPD
503 output frequency is below the DC Braking
Start Frequency (Cn-10).

Sn-18 = 60
