Default Function
0.01 Enter the process controller proportional gain.
Quick control is obtained at high amplifi-
cation. However, if amplification is too great,
the process may become unstable.
999.0 s Enter the process controller integral time.
Obtain quick control through a short integral
time, though if the integral time is too short,
the process becomes unstable. An excessively
long integral time disables the integral action.
Default Function

Size related Enter the value of the d-axis
inductance.
Obtain the value from the permanent
magnet motor data sheet. The de-axis
inductance cannot be found by
performing an AMA.
