The setting of CT TURNS RATIO can affect the value of J 18 ARM I FB RESISTOR (P.395).
Check J 18 ARM I FB RESISTOR (P.395) and the setting of the J18 jumper if you change
CT TURNS RATIO .
MOTOR RATED ARM AMPS
(P.008)
The rated armature
current from the
motor nameplate. Parameter Range: 0 to 3000.0 amps
Default Setting: 8.0 amps
Parameter Type: Configurable
OIM Menu Path(s): Current Minor Loop ( CML ) - CML Feedback Scaling
Quick Start
The setting of MOTOR RATED ARM AMPS can affect the value of J 18 ARM I FB RESISTOR
(P.395). Check J 18 ARM I FB RESISTOR (P.395) and the setting of the J18 jumper if
you change MOTOR RATED ARM AMPS .
!
ATTENTION: This parameter must be less than the motor rated armature
amps or drive current rating listed on the motor nameplate. If this is
configured incorrectly, overcurrent or excess heating of the motor could
result. Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
CT TURNS RATIO
(P.010)
The drive current
transformer turns
ratio (Tp/Tn).
See Regulator board
replacement
instructions for
information on
determining the
CT
TURNS RATIO . This
parameter is not
restored if a Restore
Defaults is done.
Parameter Range: 139

Default Setting: n/a
(set at the factory based on the drive horsepower and
AC line voltage.
Parameter Type: Configurable

!
ATTENTION: The CT TURNS RATIO parameter is used in the calculation
of the burden resistor value. Do not change this parameter from its
factory default value unless you are replacing the Regulator board.
Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
