General Precautions
Prior to installation of either the Stand Alone Regulator or Gate Amplifier, read
the following precautions.
ATTENTION: Energized industrial control equipment can be hazardous.
Severe injury or death can result from electrical shock, burn, or unintended
actuation of controlled equipment. Hazardous voltages may exist in the
cabinet even with the circuit breaker in the off position. Recommended
practice is to disconnect and lock out control equipment from power
sources, and discharge stored energy in capacitors, if present. If it is
necessary to work in the vicinity of energized equipment, the Safety
Related Practices of NFPA 70E, “ELECTRICAL SAFETY FOR EMPLOYEE
WORKPLACES” must be followed. DO NOT work alone on energized
equipment!
ATTENTION: The following information is merely a guide for proper
installation. The National Electrical Code and any other governing regional
or local code will overrule this information. Rockwell Automation cannot
assume responsibility for the compliance or the noncompliance to any
code, national, local or otherwise for the proper installation of this drive
regulator or associated equipment. A hazard of personal injury and/or
equipment damage exists if codes are ignored during installation.
ATTENTION: The installation of the Stand Alone Regulator and/or the
Gate Amplifier must be planned such that all cutting, drilling, tapping and
welding can be accomplished with the Gate Amplifier removed from the
enclosure. The Stand Alone Regulator and Gate Amplifier are of the open
type construction and any metal debris must be kept from falling into the
enclosure. Metal debris or other foreign matter may become lodged in the
circuitry resulting in component damage.
ATTENTION: An incorrectly applied or installed Stand Alone Regulator or
Gate Amplifier can result in component damage or a reduction in product
life. Wiring or application errors, such as, incorrect or inadequate supply
voltage or excessive ambient temperatures may result in malfunction of
the system.
ATTENTION: Only qualified personnel familiar with DC drives and
associated machinery should plan or implement the installation, start-up
and subsequent maintenance of the system. Failure to comply may result
in personal injury and/or equipment damage.
ATTENTION: The Stand Alone Regulator and Gate Amplifier contain ESD
(Electrostatic Discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing or repairing
this assembly. Component damage may result if ESD control procedures
are not followed. If you are not familiar with static control procedures,
reference A-B publication 8000-4.5.2, “Guarding Against Electrostatic
Damage” or any other applicable ESD protection handbook.

Chapter 1 Introduction
Product Overview
The PowerFlex DC Stand Alone Regulator (SAR) and Gate Amplifier products
provide an integrated solution for controlling external DC power modules.
Stand Alone Regulator (SAR)
The SAR is a DC drive regulator that provides armature regulation, armature
SCR gate signals and a regulated field supply. The SAR field supply consists of a
single phase, two quadrant (non-reversing,) full wave rectified bridge, available as
40 or 70 Amps. The SAR supports an AC line input voltage range of 230VAC to
690VAC and a field input voltage range of 100VAC to 460VAC.
The SAR uses feedback signals from the AC input line to monitor the incoming
voltage level in order to establish the SCR gate firing sequence relative to the AC
line. The SCR gate firing for the field bridge is established from the AC lines that
supply the field, independent of the armature firing circuit. DC feedback signals
are used to monitor the output voltage from the power module. Additionally,
current signals received from current transformers is used by the SAR regulator to
monitor and control current. The SAR catalog numbers are listed in Catalog
Numbers on page 12. The SAR must be used with the Gate Amplifier in order to
interface with a DC power module(s).
Gate Amplifier
The Gate Amplifier is used to amplify the SCR gate signals supplied by a DC
drive regulator. The gate signal source to the Gate Amplifier can be provided by
either the PowerFlex DC SAR, or the SD3000 PLUS. The Gate Amplifier unit
provides a separate input D-Shell connector for each product. The Power
Module Interface (PMI) Rack is also compatible with the Gate Amplifier and
uses the SD3000 PLUS inputs. The Gate Amplifier model number and
corresponding connection cables part numbers are listed in Model and Cable
Model/Part Numbers on page 12.
In addition to amplifying the gate signals, the forward and reverse signals
provided by the Gate Amplifier are “fanned-out” to enable the driving of multiple
power modules. Four S6 bridges forward and four S6 bridges reverse. When the
S6 bridges are connected in an anti-parallel configuration, the topology is an S6R
providing both motoring and regenerative capability.
The external 48V gate power supply capability of the Gate Amplifier provides the
means to supply additional gate current and voltage and also support the firing of
gate coupler boards connected in series (which requires additional voltage).
Connecting gate couplers in series forces the simultaneous firing of the SCRs,
with power connections in series or parallel. An internal “diode OR” circuit
ensures that the gates are powered by whichever gate power supply voltage is the
greater in amplitude, the internal or the external power supply.

Chapter 2 Stand Alone Regulator Installation, Wiring and Configuration
CE Conformity
Conformity with the Low Voltage Directive and Electromagnetic Compatibility
Directive has been demonstrated using harmonized European Norm (EN)
standards published in the Official Journal of the European Communities. The
PowerFlex DC Stand Alone Regulator complies with the EN standards listed
when installed according to this User Manual.
CE Declarations of Conformity are available online at:
• EN 50178 Electronic equipment for use in power installations.
EMC Directive (2004/108/EC)
• EN 61800-3 Adjustable speed electrical power drive systems Part 3: EMC
product standard including specific test methods.
General Considerations
• For CE compliance, the SAR installation must satisfy requirements related
to both EN 50178 and EN 61800-3 provided in this document.
• The SAR complies with the EMC requirements of EN 61800-3 when
installed according to good EMC practices and the instructions provided
in this document. However, many factors can influence the EMC
compliance of an entire machine or installation, and compliance of the
SAR itself does not necessarily ensure compliance of all applications.
• The SAR is not intended to be used on public supply networks which
supply domestic premises. Without additional mitigation, radio frequency
interference is expected if used on such a network. The installer is
responsible to take measures such as supplementary line filters and
enclosures to prevent interference, in addition to the installation
requirements of this document.
Installation Requirements Related to EN 50178 and the Low
Voltage Directive
• The SAR is compliant with the CE LV Directive when used at altitudes no
greater than 2000 m (6562 ft).
• The SAR provided in enclosure type IP20 must be installed in a pollution
degree 1 or 2 environment to be compliant with the CE LV Directive.
Characteristics of the different pollution degree ratings are provided in

• The SAR must be installed in a suitable enclosure with at least an IP4X
rating at the top of the enclosure.
• The SAR may produce leakage current in the protective earthing
conductor which exceeds 3.5 mA AC and/or 10 mA DC. The minimum
size of the protective earthing (grounding) conductor used in the
application must comply with local safety regulations for equipment with
high protective earthing conductor current.
• The SAR may not be powered from a “corner-earthed” supply system in
order to maintain compliance with the CE LV Directive.
Installation Requirements Related to EN 61800-3 and the EMC
Directive
• The SAR must be earthed (grounded) as described in this User Manual.
• Output power wiring to the motor (field excitation) must employ cable
with a braided shield providing 75% or greater coverage, or the cable must
be housed in metal conduit, or equivalent shielding must be provided.
Continuous shielding must be provided from the SAR enclosure to the
motor enclosure. Both ends of the motor cable shield (or conduit) must
terminate with a low-impedance connection to earth.
• At the motor end, the motor field excitation cable shield or conduit must
terminate in a shielded connector which must be properly installed in an
earthed motor wiring box attached to the motor. The motor wiring box
cover must be installed and earthed.
• All control (I/O) and signal wiring to the SAR, including gate firing
control, must use cable with a braided or foil shield providing 75% or
greater coverage, or the cables must be housed in metal conduit, or
equivalent shielding must be provided. Only the SAR end of the cable
shield should be terminated with a low impedance connection to earth.
• Power cabling must be separated from control and signal wiring wherever
possible.

Safety Ground (PE)
The Safety Ground - PE must be connected to system ground. Ground
impedance must conform to the requirements of national and local industrial
safety regulations and/or electrical codes. The integrity of all ground connections
should be periodically checked.
For installations within a cabinet, a single safety ground point or ground bus bar
connected directly to building steel should be used. All circuits should be
grounded independently and directly to this point/bar.
AC/DC Voltage and Motor
Armature Voltage Feedback
Wiring
The SAR requires AC feedback connections to connector KP (terminals U, V,
and W) from the incoming line to monitor the incoming voltage level and
establish the SCR gate firing sequence relative to the AC line. DC feedback
connections to connector KP (terminals C and D) are required to monitor the
voltage output from the DC power module. The combined information from the
AC and DC feedback inputs is used to determine if the SCRs are firing properly.
See Figure 4 on page 19
S6R.
Fuses are required between the DC output power wiring on the DC power
module to connector KP on the SAR. This will limit the current to the regulator
in the event of an internal fault in the SAR. The recommended fuse types are
shown in DC Feedback Fusing Requirements
for recommended wiring for a typical SAR interface to
on page 22.

Control Circuit Power
Wiring
The control circuit for the SAR (not identified in the drawings contained in this
manual) must be powered by an external 230V AC or 115V AC, single phase
power supply. This power supply provides power for the SAR cooling fans and a
HIM, communication adapter, I/O, encoder, or DC analog tachometer (if
installed). See “Control Circuit Input Power” in the PowerFlex Digital DC Drive
User Manual, publication 20P-UM001
In addition, the control circuit power input terminals require short circuit
protection. See “Control Power Protection” in the PowerFlex Digital DC Drive
User Manual, publication 20P-UM001

Chapter 2 Stand Alone Regulator Installation, Wiring and Configuration
Relay Output and Thermistor/Thermal Switch Wiring
Two normally open relay outputs and one motor thermistor (PTC) or thermal
switch input are available for use and must be configured with the appropriate
parameters. See “Relay Outputs” and “Thermistors and Thermal Switches” in the
PowerFlex Digital DC Drive User Manual, publication 20P-UM001
I/O, Digital Encoder, and DC Analog Tachometer Wiring
The following standard I/O and feedback options are available with the SAR.
• Eight digital inputs, four digital outputs, three analog inputs, and two
analog outputs are available. Additional digital and analog I/O is available
when using the optional I/O expansion circuit board.
• An input terminal block is available for an incremental, dual channel, two
channel optional (with jumper), differential (recommended) or singleended encoder with an input voltage configurable for +2.5V…5.2V or
+5.4V…15.2V.
for details.
SAR Motor Field Current
Configuration
• An input terminal block is available for a DC analog tachometer with a
maximum input voltage of 22.7V, 45.4V, 90.7V, 181.6V, or 302.9V and an
input current of 8 mA full scale.
See “I/O Wiring” in the PowerFlex Digital DC Drive User Manual, publication
20P-UM001
for details.
Resolver Feedback Option Module Wiring
A resolver feedback module is available for purchase separately from the SAR.
The resolver feedback option module includes the PowerFlex DC Drive Resolver
Feedback Option Module Installation Instructions, publication 20P-IN071
the PowerFlex Digital DC Drive User Manual, publication 20P-UM001
resolver configuration details.
The SAR motor field current must be configured with both a hardware DIP
switch (S14) and by setting parameter 374 [Drv Fld Brdg Cur] to the appropriate
value. For each field current rating, in this case 40 and 70 A, there are several
ranges to choose from with regard to the maximum range of the field current.
The lowest range that is greater than the maximum motor field current should be
selected to ensure the best resolution. See “Field Current Configuration” in the
PowerFlex Digital DC Drive User Manual, publication 20P-UM001
instructions.
