FIELD REF REGISTER (P.513)
Only available if the Field Current Regulator kit is installed.
Current reference for the field control loop field. This is the field current reference when the drive is not
in field economy. See MOTOR HOT FLD AMPS for the block diagram.
Parameter Range: 0 to MOTOR HOT FLD AMPS
Default Setting: MOTOR HOT FLD AMPS
Parameter Type: Tuneable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Tuning
Refer also to Parameters: MOTOR HOT FLD AMPS (P.510)
FIELD REF SELECT (P.521)
Selects the reference source for a field current regulator. A field current regulator must be installed for
this parameter to be effective. An I/0 expansion kit must be installed to select ANALOG IN 1or ANALOG
IN 2.
REGISTER is the FIELD REF REGISTER (P.513) network register. (Drop_1, register 37).
Parameter Range: 1 = REGISTER
2 = ANALOG MAN TRIM REF
3 = ANALOG IN 1
4 = ANALOG IN 2.
Default Setting: 1
Parameter Type: Configurable
OIM Menu Path(s): Additional Parameters
FLD FEEDBACK GAIN ADJ (P.516)
Only available if the Field Current Regulator kit is installed.
Gain adjustment for the field feedback. See MOTOR HOT FLD AMPS for the block diagram.
In most cases, this will be set for unity gain, typically 1.000.
Parameter Range: 0.90 to 1.100
Default Setting: 1.000
Parameter Type: Tuneable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Feedback Scaling
Refer also to Parameters: FIELD FEEDBACK (P.589)
MOTOR HOT FLD AMPS (P.510)
FLD WEAKEN LEAD FREQ (P.520)
Only available if the Field Current Regulator kit is installed.
PI block lead frequency of the field control loop's armature voltage regulator.
See FIELD AUTO WEAKEN for the block diagram.
Parameter Range: 0.01 to 56.50 rad/s
Default Setting: 0.30 rad/s
Parameter Type: Tuneable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Tuning
