1.0 INTRODUCTION
The products described in this instruction manual are manufactured or distributed by Reliance
Electric Industrial Company.
This instruction manual describes how to install and configure the optional Field Current Regulator
kits used by FlexPak 3000 drives. The Field Current Regulator, which includes a field regulator and
a field supply, can be used only in drives that have software version 3.00 (REGULATOR SW
VERSION parameter = 3.00) or later. When the kit is installed, a field control loop is enabled, allowing
the user to adjust field control functions. The field control loop operates in both the constant torque
(armature control) range and the constant power (field control) range. See Appendix A for a
description of the field control loop.
There are three Field Current Regulator kits available for use in FlexPak 3000 drives. They differ
according to the maximum motor field current they support. Use the kit that provides the maximum
motor field current (including that necessary for field forcing) required for your application. Note that
using a Field Current Regulator with a higher amperage rating than is needed will decrease control
resolution. Refer to table 1.1 to ensure you have the correct kit for your application and to table 1.2
for a list of the kit contents. See figures 1.1 and 1.2 for illustrations of the Field Current Regulator
board and cable assemblies.

Appendix A
Field Current Regulator Description
Description of the Field Control Loop
The FlexPak 3000 version 3 regulator will detect the presence of the Field Current Regulator kit at powerĆup.
The output parameter FLD CURRENT REGULATOR indicates whether or not the Field Current Regulator kit is
installed. When the Field Current Regulator kit is installed, the field current control loop operates and drive
parameters ENHANCED FLD VOLT ADJ and J21 FLD SUPPLY JUMPER are ignored. The regulated field loss
and field economy circuits become active in place of those used by the standard and enhanced field supĆ
plies. See figure A.1 for a block diagram of the field control loop.
NOTE: The regulator board jumper J20 (Field Loss Detect) is ignored when the Field Current Regulator is
installed. Therefore, setting J20 to the DISABLE position will NOT disable field loss detection.
The field control loop contains two regulators: a field current regulator and an armature voltage (counterĆEMF
or CEMF) regulator. The field control loop can be configured to decrease armature voltage when the armaĆ
ture voltage feedback (ARMATURE VOLTAGE) exceeds the FLD WEAKEN THRESHOLD voltage and the field
begins to weaken (see figures A.1 and A.2). The armature IR drop can be compensated for by using the IR
COMPENSATION parameter (P.206).
The output of the Field Current Regulator determines the firing angle of the regulated field supply gate firing
circuit. The output parameter FIELD DELTA represents the angle in degrees. If the factory defaults for the
Field Current Regulator are in effect, it will operate in a fixed voltage mode by firing the field SCRs at a fixed
angle of 117º. This will produce a field voltage of 150 VDC at 230 VAC line input or 300 VDC at 460 VAC line
input. For other motor field voltages, MOTOR HOT FLD AMPS must be set properly before the motor field is
connected. While the Field Current Regulator is producing fixed voltage, the value for MOTOR HOT FLD
AMPS will be set to 0.01 amps. After a valid value is entered for MOTOR HOT FLD AMPS, the userĆassigned
value for FIELD LOSS THRESHOLD becomes effective. The Field Current Regulator will NOT regulate field
current until a valid value for MOTOR HOT FLD AMPS is entered. While in fixed voltage mode, a field loss
fault will only occur if there is a complete loss of field current. This is similar to having a standard or enhanced
field supply installed.
CAUTION: If the factory defaults for the Field Current Regulator are not in effect (e.g., MOTOR HOT FLD
AMPS was modified via the network or CS3000), extreme care must be exercised to ensure the correct value
for MOTOR HOT FLD AMPS is present when power is applied to the drive. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
Both field loop regulators contain proportional plus integral (PI) control. There is no userĆconfigurable low
limit parameter associated with these PI blocks. The low limit is always fixed at zero. The high limit (FIELD
DELTA HI LIM) is userĆconfigurable up to 180 degrees, allowing fullĆon field voltage of 207 VDC @ 230 VAC
and 414 VDC @ 460 VAC. To regulate greater field voltages, a stepĆup transformer must be used to supply
the AC side of the Field Current Regulator.
As the motor speed increases beyond base speed, the armature voltage will increase above rated voltage.
The PI block monitoring armature voltage will reduce the high limit of the PI block controlling field current. As
field current decreases, field flux and armature voltage will also decrease. Field current continues to decrease
until armature voltage is reduced to FLD WEAKEN THRESHOLD volts. Control of armature voltage during
field weakening is only permitted when a tachometer is used (FEEDBACK SELECT ≠ ARMATURE VOLTS).
Automatic field weakening can be disabled by setting FIELD AUTO WEAKEN = DISABLED. The drive can
also be operated in the constant power (field control) range by controlling the field current reference excluĆ
sively (FIELD REF REGISTER).

Figure A.2 Ć Drive Operation Over the Constant Torque and Constant Power Range
Field Current Feedback Scaling
There are three Field Current Regulator ratings: 4 amps, 10 amps, and 15 amps. The Regulator board hardĆ
ware provides three different gains for the field current feedback signal: 1, 2, and 5. The user must enter the
motor nameplate value for rated field amps (MOTOR HOT FLD AMPS) to properly scale the feedback signal.
The software will automatically select the feedback gain (in hardware) which produces the largest full scale
digital value in the analogĆtoĆdigital converter. MOTOR HOT FLD AMPS will be limited based on the rating of
the Field Current Regulator kit installed. Table A.1 shows what the software will select as the feedback gain
depending on motor hot field amps.

AĆ3
When the Field Current Regulator is operating in fixed voltage mode, a field current loss fault will be generĆ
ated only when there is a complete loss of field current. When the Field Current Regulator is regulating field
current (that is, not in fixed voltage mode), a field current loss fault will be generated when the field current
drops below the userĆset FIELD LOSS THRESHOLD.
The same field feedback signal used by the Field Current Regulator is used by the field loss detection circuit.
The field current feedback will be compared against a userĆentered FIELD LOSS THRESHOLD. If the feedĆ
back is less than the threshold value, a fault will be generated. FIELD LOSS THRESHOLD is entered as a perĆ
centage of
MOTOR HOT FLD AMPS (0Ć100% (speed regulator), 50Ć100% (armature voltage regulator)). FIELD ECONĆ
OMY REF must be set above FIELD LOSS THRESHOLD to avoid field loss faults when the drive enters field
economy.
A field loss fault will also occur if the digital value on the A/D converter reaches full scale (approximately 28%
above the rated field output).
The regulator board hardware jumper, J20 Field Loss Detect, is designed to allow the user to separately exĆ
cite the motor field winding, and is not intended as a means of bypassing field loss detection when using an
internal field supply. Therefore, when the Field Current Regulator kit is installed, this jumper is ignored. Note
that leaving J20 in the DISABLE position will NOT disable field loss detection.
The output parameter FIELD ECONOMY ACTIVE indicates when field economy is active. Field economy beĆ
comes active after a userĆdefined time delay (FIELD ECONOMY DELAY) from the time the motor stops or the
drive is powered up. When the Field Current Regulator is operating in fixed voltage mode, a constant field
voltage is generated, regardless of the state of FIELD ECONOMY ACTIVE.
The Field Current Regulator will provide field economy with a userĆadjustable field current reference (FIELD
ECONOMY REF). This parameter is entered as a percentage of MOTOR HOT FLD AMPS. FIELD ECONOMY
REF must be set above FIELD LOSS THRESHOLD to avoid nuisance field loss faults.
Overspeed detection is active only when a tachometer is being used (FEEDBACK SELECT ≠ ARMATURE
VOLT). Because of this, the amount of field weakening is limited when the drive is configured as a voltage
regulator (FEEDBACK SELECT = ARMATURE VOLT).
Armature overvoltage protection is always active, regardless of the type of feedback. This will reduce the
chance of overvoltaging the armature due to a weakened field. An overvoltage fault will occur when the armaĆ
ture terminal voltage exceeds 130 percent of MOTOR RATED ARM VOLTS.
