PM Motor current loop controller parameters
 When 11-51(P.390) = 0, the speed loop PI parameters (11-00(P.320)、11-01(P.321)、11-03(P.323)、11-04(P.324)、
11-23(P.412)、11-24(P.413)) are set manually;
 when 11-51(P.390) = 1, the speed The loop PI parameters (11-00(P.320)、11-01(P.321)、11-03(P.323)、11-04(P.324)、
11-23(P.412)、11-24(P.413)) are automatically set, and with the reasonable setting of system inertia (05-17/05-18),
Can achieve the ideal speed loop response characteristics; please adjust 11-48(P.387)、11-49(P.388)、11-50(P.389)
respectively according to the responsiveness requirements. The larger the setting, the faster the speed loop
response. If the setting is too large, it will cause system oscillation. We suggest increases
11-48(P.387)~11-50(P.389) slowly, and return to the previous setting value right after the system oscillates.

Set velocity loop output low-pass filter time constant
If vibration is caused due to low mechanical rigidity, please gradually increase this value based on the increment of
1.0ms, usually not required to be set.
