What can cause the display to show DCb on an ATV58
All models and serial numbers
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.
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".
