What can cause the display to show DCb on an ATV58

Issue:
DCB
 
Product Line:
ATV58, Flex58
 
Environment:
All models and serial numbers

Cause:
The DCb indicates a drive state is performing direct current injection and can be caused by
 1.  A logic input with DC injection having been enabled.
 2.  The deceleration ramp has completed and the automatic dc injection is being enabled.

Resolution:
1.  Un assign the DC Injection function of the logic input.
2. This is a normal function to cause the drive to come to a complete stop.  If this is not required then it can be disabled by setting parameter AdC to "no".
