D-30 Programming Parameters
141
Bus Feedback
[Bus Feedback]
This parameter displays the value of the bus
feedback. This bus feedback value is compared
with the Bus Reference (P128) to determine the
bus error (P142) which needs to be corrected by
the PI regulator.

142
Voltage Loop Error
[Bus Error]
This parameter shows the error in the DC bus that
needs to be corrected through the PI regulator.
This value is used to adjust the bus voltage
(shown by the Bus Feedback (P141)) to the
commanded voltage (shown by the Bus
Reference (P128)).

143
Scaled Bus Feedback
[Scaled Bus Fbk]
This parameter shows the calibrated bus
feedback. The value of this parameter is used to
determine the Bus Feedback (P141) and is used
to calculate the DC Bus Current (P107).

Bus Voltage Feedback Calibration
[Bus Volt Cal]
This parameter is used to adjust the voltage value
shown in the bus feedback parameters (i.e. P140,
P141, P143).
To calibrate the feedback, adjust this parameter
until P143 (Scaled Bus Feedback) is equal to the

parameter can only be set when the RGU is
Disabled.
