FLD WEAKEN LEAD FREQ
(P.520)
PI block lead
frequency of the field
control loop’s
armature voltage
regulator.
Parameter Range: 0.01 to 282.70 RAD / S
Default Setting: 0.50 RAD / S
Parameter Type: Tunable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Tuning
FLD WEAKEN PROP GAIN (P.519)
The proportional gain
of the field control
loop’s armature
voltage regulator. Parameter Range: 0.01 to 128.00
Default Setting: 1.60
Parameter Type: Tunable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Tuning
FLD WEAKEN THRESHOLD (P.518)
Sets the point at
which the field control
loop begins
regulating armature
voltage and the field
begins to weaken. Parameter Range: 0 to 120% of MOTOR RATED ARM VOLTS (P.009)
Default Setting: 95% of MOTOR RATED ARM VOLTS (P.009)
Parameter Type: Tunable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Tuning
If IR compensation is used, the threshold is FLD WEAKEN THRESHOLD at rated
armature current.
