9-6 Adjusting Voltage and Current Regulation Parameters
1. Set P219 to “0” for normal operation (this value cannot be
changed while the unit is running).
2. Select values for Wn (P137) between 0 and 32767 radians/
second, and Kn (P138) between 0 and 1 of the feedback filter.
3. P141 contains the final DC bus feedback value.
Comparing the DC Bus Reference with the DC Bus Feedback
As shown in Figure 9.5, the error signal is the difference between the
DC bus reference (P128) and the DC bus feedback (P141).
