P03.37
High-frequency
current-loop
proportional
coefficient
In the closed-loop vector control mode
(P00.00=3), when the frequency is lower than
the current-loop high-frequency switching
threshold (P03.39), the current-loop PI
parameters are P03.09 and P03.10; and when
the frequency is higher than the current-loop
high-frequency switching threshold (P03.39),
the current-loop PI parameters are P03.37
and P03.38.
Setting range of P03.37: 0–20000
Setting range of P03.38: 0–20000
Setting range of P03.39: 0.0–100.0% (of the
maximum frequency)
