FLD WEAKEN PROP GAIN (P.519)
Only available if the Field Current Regulator kit is installed.
The proportional gain of the field control loop's armature voltage regulator.
See FIELD AUTO WEAKEN for the block diagram.
Parameter Range:
0.01 to 128.00
Default Setting:
0.80
Parameter Type:
Tuneable
OIM Menu Path(s):
Field - Field Current Regulator - Field Loop Tuning
Refer also to Parameters:
FIELD AUTO WEAKEN (P.517)
FLD WEAKEN LEAD FREQ (P.520)
FLD WEAKEN THRESHOLD (P.518)
Only available if the Field Current Regulator kit is installed.
Sets the point at which the field control loop begins regulating armature voltage and the field begins to
weaken. If IR compensation is used, the effective threshold is FLD WEAKEN THRESHOLD less IR
COMPENSATION at rated armature current. See FIELD AUTO WEAKEN for the discussion and block
diagram.
Parameter Range:
0 to 120% of MOTOR RATED ARM VOLTS
Default Setting:
95% of MOTOR RATED ARM VOLTS
Parameter Type:
Tuneable
OIM Menu Path(s):

MOTOR RATED ARM VOLTS (P.009)
FREQ IN FULL SCALE (P.424)
Only available if the I/O Expansion kit is installed.
Specifies the maximum input frequency. This is the frequency that corresponds to a full scale value. For
example, if the frequency input will be used as the speed loop reference (selected by AUTO
REFERENCE SELECT, P.103), this input frequency would correspond to TOP SPEED (P.011), because
TOP SPEED is the basis for speed loop scaling.
Parameter Range:
2.0 to 250.0 kHz
Default Setting:
250.0 kHz
Parameter Type:
Configurable
OIM Menu Path(s):
Input/Output - Frequency I/O
Refer also to Parameters:
FREQ IN (P.491)
FREQ IN ZERO (P.423)
FREQ IN ZERO (P.423)
Only available if the I/O Expansion kit is installed.
Specifies the minimum input frequency. This is the frequency that corresponds to a value of zero. If the
input frequency drops below the frequency specified by this input parameter, the resulting digital value
remains zero (it will not go negative).
Parameter Range:
2.0 to FREQ IN FULL SCALE kHz
Default Setting:
2.0 kHz
Parameter Type:
Configurable
