4.0 Description of Functionality:
4.1 Full Range DC Injection
When n005 = 2 and the run command is removed, the drive will Baseblock for the time in parameter n170
(Minimum Baseblock Time) and then apply DC injection. The DC injection time is based on n090 (DC
Injection Time at Stop) and output frequency as shown below. Although the minimum Baseblock time
can be set as low as 0.1 Sec, caution should be observed when setting this parameter to avoid
Overvoltage or Overcurrent faults. The acceptable minimum setting will vary based on the motor and
application.
