Iq Reference Rate Limit
[Iq Change Rate]
This parameter defines the rate limit for the Iq
reference. This value is used by the current limiter
to prevent the Iq Reference (P96) from changing
too rapidly.

Related Parameters
P198
For example, a 575V AC M-code RGU, bydefault,
would not allow the Iq reference to change more than
200A (33.33% of 602A (P11)).

Per Unit Internal Capacitance Charge Rate
[Int Charge Rate]
This parameter indicates the charge rate of the
RGU internal capacitance.
To determine the rate, divide P16 (Nominal DC
Bus Voltage) by this value.

External Capacitance
[Ext Capacitance]
This parameter specifies the estimated sum
capacitace of the all the AC units connected to the
DC bus. This value is used to calculate the
proportional and integral gains in the PI regulator
(P118 and P119).
