456 [Fld Weaken Ratio]
The ratio of Motor Nameplate Base Speed to Par 45 [Max Ref Speed] when
Par 469 [Field Mode Sel] = 1 “Field Weaken”. This value is the percentage of
the maximum application speed when field weakening will begin: “Motor
Base Speed” / Par 45 [Max Ref Speed] x 100. If Par 469 [Field Mode Sel] = 0
“Base Speed”, this parameter must be = 100%. Leave set to the default value
for permanent magnet motor applications. Default:

463 [Flux Filter BW]
Adjustable low pass filter on the value of Par 500 [Flux Ref Pct]. The filtered
result is used by the Torque Reference divide by flux function. Leave set to the

467 [Max Fld Flux Pct]
Maximum allowable field flux. The maximum value (100%) corresponds to
the value set in Par 280 [Nom Mtr Fld Amps]. The value of this field linearly
affects the field current, unless a flux curve is set in Pars 916, 917, and 918
