FIELD DELTA HIGH LIM (P.587)
High limit of the field current PI block. See FIELD AUTO WEAKEN for block diagram.
Parameter Range: 0 to 180 Degree
Default Setting: 130 Degree
Parameter Type: Configurable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Test Points
Refer also to Parameters: FIELD AUTO WEAKEN (P.517)
FIELD ECONOMY DELAY (P.501)
After the motor stops, the drive maintains full field for FIELD ECONOMY DELAY minutes before
entering field economy. When the motor starts again, the drive immediately returns to full field. FIELD
ECONOMY DELAY has no effect on the operation of the standard field supply. Field economy cannot be
disabled.
Parameter Range: 0 to 27 minutes
Default Setting: 5 minutes
Parameter Type: Tuneable
OIM Menu Path(s): Field - Standard/Enhanced Field Supply
Field - Field Current Regulator - Field Loop Configure
FIELD ECONOMY REF (P.511)
Only available if the Field Current Regulator Kit is installed.
The percentage of MOTOR HOT FLD AMPS set as a reference for field economy mode.
This parameter must be set above the FIELD LOSS THRESHOLD value to avoid field loss faults.
Field economy becomes active after the delay specified by FIELD ECONOMY DELAY from the time the
motor stops. The drive enters field economy when first powered up. FIELD ECONOMY ACTIVE
indicates when field economy is active.
Parameter Range: 0 to 100%
Default Setting: 0%
Parameter Type: Tuneable
OIM Menu Path(s): Field - Field Current Regulator - Field Loop Configure
Refer also to Parameters: FIELD ECONOMY ACTIVE (P.599), FIELD ECONOMY DELAY (P.501),
FIELD LOSS THRESHOLD (P.512), FIELD REF REGISTER (P.513),
MOTOR HOT FLD AMPS (P.510)
WARNING
The incorrect setting of this parameter can cause a motor overvoltage condition.
Set MOTOR HOT FLD AMPS to the motor's nameplate value. Make sure FIELD ECONOMY REF
and/or FIELD REF REGISTER (P.513) is above FIELD LOSS THRESHOLD (P.512).
Failure to observe this precaution can result in bodily injury and damage to the equipment.
