FIELD DELTA (P.588)
The angle of the output of the field current regulator to the regulated field supply gate firing circuit.
Output of the field current PI block.
Parameter Range: 0 to 180 Degree
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Test Points
Refer also to Parameters: FIELD PI PROP GAIN (P.514), FIELD PI LEAD FREQ (P.515)
FIELD ECONOMY ACTIVE (P.599)
Indicates the present state of field economy.
OIM Menu Path(s): Field - Standard/Enhanced Field Supply
Field - Field Current Regulator - Field Loop Test Points
FIELD FEEDBACK (P.589)
Motor field current feedback signal after scaling and gain. Used by the field current regulator and field
loss detection circuit.
Parameter Range: MOTOR HOT FLD AMPS
OIM Menu Path(s): Field - Field Current Regulator -Field Loop Feedback Scaling
or Field - Field Current Regulator - Field Loop Test Points
Refer also to Parameters: MOTOR HOT FLD AMPS (P.510)
FIELD REFERENCE (P.590)
Field current reference testpoint. It is the limited value of FIELD REF REGISTER or the field economy
reference (when FIELD ECONOMY ACTIVE is ON). See MOTOR HOT FIELD AMPS for block diagram.
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Test Points
Refer also to Parameters: FIELD REF REGISTER (P.513), FIELD ECONOMY ACTIVE (P.599)
MOTOR HOT FLD AMPS (P.510)
FLD CURRENT REGULATOR (P.586)
Indicates the rating of the Field Current Regulator kit, if installed. Refer to the Field Current Regulator kit
instruction manual 49’1345.
Parameter Range: NOT INSTALLED, 4 AMP, 10 AMP, 20 AMP (actually 12 or 15 A)
OIM Menu Path(s): Field - Field Current Regulator
or Field - Standard/enhanced Field Supply or Drive Information
FREQ IN (P.491)
Only available if the I/O Expansion kit is installed.
The digital value of the frequency input (terminals 39, 40, and 41 on the I/O Expansion board).
FREQ IN is scaled between FREQ IN ZERO and FREQ IN FULL SCALE.
Parameter Range: 0 to 4095
OIM Menu Path(s): Input/Output - Frequency I/O
Refer also to Parameters: FREQ IN FULL SCALE (P.424), FREQ IN ZERO (P.423)
FREQ IN is zero when the frequency at the input is less than or equal to FREQ IN ZERO.
It is 4095 when the frequency equals FREQ IN FULL SCALE.
