▲ Set FIELD CURRENT 6 (P.527).
▲ Set FIELD CURRENT 7 (P.528).
▲ Set FIELD CURRENT 8 (P.529).
▲ Set FIELD SHAPING LAG (P.538) to specify a lag frequency for the field
shaping output.

Set FIELD LOSS THRESHOLD (P.512). This is the value of motor field current that
is compared with FIELD FEEDBACK (P.589), and is set as a percentage of
MOTOR HOT FLD AMPS (P.510). It is usually set for 85% of the motor nameplate
field weakened current to check for field loss. The choices are:
50 to 100% of MOTOR HOT FLD AMPS (P.510) when FEEDBACK SELECT (P.200) is
set to ARMATURE VOLT .
0 to 100% of MOTOR HOT FLD AMPS (P.510) when FEEDBACK SELECT (P.200) is
set to DC TACH or ENCODER .
.
Range: 0 to 5000 RPM P.537 = RPM
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.522 = AMPS
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.523 = AMPS
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.524 = AMPS
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.525 = AMPS
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.526 = AMPS
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.527 = AMPS
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.528 = AMPS
Range: 0.00 to MOTOR HOT FLD AMPS (P.510) P.529 = AMPS
Range: .01 to 13.96 RAD / S P.538 = RAD / S
!
ATTENTION: Setting FIELD LOSS THRESHOLD (P.512) too low can
eliminate field loss protection. Set P.512 such that field loss protection
will shut the drive down before it reaches unsafe speed. Failure to
observe this precaution could result in severe bodily injury or loss of life.
Range: 50 to 100% of P.510 or 0 to 100% of P.510 P.512 = %
