Generating a Voltage Loop I
d
Command
The voltage loop I
d
command can originate in one of four ways as
determined by user-configurable P103. That resulting I
d
command is
then processed through the I
d
current limiter to arrive at a voltage
loop I
d
command. The current limiter makes adjustments to maintain
the minimum and maximum I
d
limit values. Refer to Figure 9.8 for a
firmware diagram.
