Wire/Cable Types
AC drive installations have specific requirements for cables. Wire or cable
selection for a drive application must consider a variety of criteria.
The following section covers the major issues and proper selection of cable.
Recommendations are made to address these issues. Cable materials and
construction must consider the following:
• Environment including moisture, temperature and harsh or corrosive
chemicals.
• Mechanical needs including geometry, shielding, flexibility and crush
resistance.
• Electrical characteristics including cable capacitance/charging current,
resistance/voltage drop, current rating and insulation. Insulation may be
the most significant of these. Since drives can create voltages well in
excess of line voltage, the industry standard cables used in the past may
not represent the best choice for customers using variable speed drives.
Drive installations benefit from using cable that is significantly different
than cable used to wire contactors and push buttons.
• Safety issues including electrical code requirements, grounding needs
and others.
Choosing incorrect cable can be costly and may adversely affect the
performance of your installation.

Wire/Cable Types
General
Material
Use Copper wire only. The wire clamp type terminals in Allen-Bradley
drives are made for use with copper wire only. If you use aluminum wire the
connections may loosen.
Wire gauge requirements and recommendations are based on 75 degrees C.
Do not reduce wire gauge when using higher temperature wire.
Exterior Cover
Whether shielded or unshielded, the cable must be chosen to meet all of the
application requirements. Consideration must be given to insulation value
and resistance to moisture, contaminants, corrosive agents and other
invasive elements. Consult the cable manufacturer and the chart below for
proper selection.

Temperature Rating
In general, installations in surrounding air temperature of 50° C should use
90°C wire (required for UL) and installations in 40°C surrounding air
temperature should use 75°C wire (also required for UL). Refer to the drive
user manual for other restrictions
The temperature rating of the wire affects the required gauge. Be certain to
meet all applicable national, state and local codes.
Gauge
The proper wire size is determined by a number of factors. Each individual
drive user manual lists a minimum and maximum wire gauge based on the
amperage rating of the drive and the physical limitations of the terminal
blocks. Local or national electrical codes also set the required minimum
gauge based on motor full load current (FLA). Both of these
requirements should be followed.
Number of Conductors
While local or national electrical codes may determine the required number
of conductors, certain configurations are recommended. Figure 1.2 shows
cable with a single ground conductor, which is recommended for drives up
to and including 200 HP (150 kW). Figure 1.3 shows cable with three
ground conductors, which is recommended for drives larger than 200 HP
(150 kW). The ground conductors should be spaced symmetrically around
the power conductors. The ground conductor(s) should be rated for full
drive ampacity.

Insulation Thickness and Concentricity
Selected wire must have an insulation thickness of equal to or more then 15
mils (0.4 mm/0.015 in.). The quality of wire should not have significant
variations on concentricity of wire and insulation.

Geometry
The physical relationship between individual conductors plays a large role
in drive installation.
Individual conductors in conduit or cable tray have no fixed relationship and
are subject to a variety of issues including: cross coupling of noise, induced
voltages, excess insulation stress and others.
Fixed geometry cable (cable that keeps the spacing and orientation of the
individual conductors constant) offers significant advantages over
individual loose conductors including reducing cross coupling noise and
insulation stress. Three types of fixed geometry multi-conductor cables are
discussed below: Unshielded, shielded, and armored.

Unshielded Cable
Properly designed multi-conductor cable can provide superior performance
in wet applications, significantly reduce voltage stress on wire insulation
and reduce cross coupling between drives.
The use of cables without shielding is generally acceptable for installations
where electrical noise created by the drive does not interfere with the
operation of other devices such as: communications cards, photoelectric
switches, weigh scales and others. Be certain the installation does not
require shielded cable to meet specific EMC standards for CE, C-Tick or
FCC. Cable specifications depend on the installation Type.
Type 1 & 2 Installation
Type 1 or 2 installation requires 3 phase conductors and a fully rated
individual ground conductor without or with brake leads. Refer to Table 1.A
for detailed information and specifications on these installations.

The outer sheathing and other mechanical characteristics should be chosen
to suit the installation environment. Consideration should be given to
surrounding air temperature, chemical environment, flexibility and other
factors as necessary in all installation types.
Shielded Cable
Shielded cable contains all of the general benefits of multi-conductor cable
with the added benefit of a copper braided shield that can contain much of
the noise generated by a typical AC Drive. Strong consideration for shielded
cable should be given for installations with sensitive equipment such as
weigh scales, capacitive proximity switches and other devices that may be
affected by electrical noise in the distribution system. Applications with
large numbers of drives in a similar location, imposed EMC regulations or a
high degree of communications/networking are also good candidates for
shielded cable.
Shielded cable may also help reduce shaft voltage and induced bearing
currents for some applications. In addition, the increased size of shielded
cable may help extend the distance that the motor can be located from the
drive without the addition of motor protective devices such as terminator
networks. Refer to Chapter 5 for information regarding reflected wave
phenomena.
Consideration should be given to all of the general specifications dictated by
the environment of the installation, including temperature, flexibility,
moisture characteristics and chemical resistance. In addition, a braided
shield should be included and specified by the cable manufacturer as having
coverage of at least 75%. An additional foil shield can greatly improve
noise containment.

Type 1 Installation
A good example of acceptable shielded cable for Type 1 installation is
Belden® 295xx (xx determines gauge) or Anixter B209500-B209507.
These cables have 4 XLPE insulated conductors with a 100% coverage foil
and an 85% coverage copper braided shield (with drain wire) surrounded by
a PVC jacket. For detailed specifications and information on these
installations, refer to Table 1.A on page 1-5.

plus one (1) shielded pair of brake conductors. For more information on this
installation, refer to Table 1.A on page 1-5.

Wire/Cable Types
Type 3 Installation
These cables have 3 XLPE insulated copper conductors, 25% minimal
overlap with helical copper tape and three (3) bare copper grounds in PVC
jacket.
TIP: Other types of shielded cable are available, but the selection of these
types may limit the allowable cable length. Particularly, some of the newer
cables twist 4 conductors of THHN wire and wrap them tightly with a foil
shield. This construction can greatly increase the cable charging current
required and reduce the overall drive performance. Unless specified in the
individual distance tables as tested with the drive, these cables are not
recommended and their performance against the lead length limits supplied
is not known. For more information, about motor cable lead restrictions
refer to Appendix A, Conduit on page 4-13, Moisture on page 4-18 and
Effects On Wire Types on page 5-1.
Armored Cable
Cable with continuous aluminum armor is often recommended in drive
system applications or specific industries. It offers most of the advantages
of standard shielded cable and also combines considerable mechanical
strength and resistance to moisture. It can be installed in concealed and
exposed manners and removes the requirement for conduit (EMT) in the
installation. It can also be directly buried or embedded in concrete.
Because noise containment can be affected by incidental grounding of the
armor to building steel (see Chapter 2) when the cable is mounted, it is
recommended the armored cable have an overall PVC jacket.
Interlocked armor is acceptable for shorter cable runs, but continuous
welded armor is preferred.
Cable with a single ground conductor is sufficient for drive sizes up to and
including 200 HP (150 kW). Cable with three ground conductors is
recommended for drive sizes larger than 200 HP (150 kW). The ground
conductors should be spaced symmetrically around the power conductors.
The ground conductor(s) should be rated for full drive ampacity.

A good example of acceptable cable for Type 5 installation is Anixter
7V-5003-3G, which has three (3) XLPE insulated copper conductors, 25%
minimal overlap with the helical copper tape and three (3) bare copper
grounds in PVC jacket. Please note that if a terminator network or output
filter is used, connector insulation must be XLPE, not PVC.
European Style Cable
Cable used in many installations in Europe should conform to the CE Low
Voltage Directive 73/23/EEC. Generally recommended are flexible cables
with a recommended bend radius of 20 times the cable diameter for
movable cable and 6 times the cable diameter for fixed installations. The
screen (shield) should be between 70 and 85% coverage. Insulation for both
conductors and the outer sheath is PVC.
The number and color of individual conductors may vary, but the
recommendation is for 3 phase conductors (customer preferred color) and
one ground conductor (Green/Yellow)

Wire/Cable Types
Input Power Cables
In general, the selection of cable for AC input power to a drive has no
special requirements. Some installations may suggest shielded cable to
prevent coupling of noise onto the cable (see Chapter 2) and in some cases,
shielded cable may be required to meet noise standards such as CE for
Europe, C-Tick for Australia/New Zealand, and others. This may be
especially true if an input filter is required to meet a standard. Each
individual drive user manual will show the requirements for meeting these
types of standards. Additionally, individual industries may have required
standards due to environment or experience.
For AC variable frequency drive applications that must satisfy EMC
standards for CE, C-Tick, FCC or other, Rockwell Automation may
recommend that the same type of shielded cable specified for the AC motors
be used between the drive and transformer. Check the individual user
manuals or system schematic note sheets for specific additional
requirements in these situations.
Motor Cables
The majority of recommendations regarding drive cable address issues
caused by the nature of the drive output. A PWM drive creates AC motor
current by sending DC voltage pulses to the motor in a specific pattern.
These pulses affect the wire insulation and can be a source of electrical
noise. The rise time, amplitude, and frequency of these pulses must be
considered when choosing a wire/cable type. The choice of cable must
consider:
1. The effects of the drive output once the cable is installed
2. The need for the cable to contain noise caused by the drive output
3. The amount of cable charging current available from the drive
4. Possible voltage drop (and subsequent loss of torque) for long wire runs
Keep the motor cable lengths within the limits set by the drive's user
manual. Various issues, including cable charging current and reflected wave
voltage stress may exist. If the cable restriction is listed because of
excessive coupling current, apply the methods to calculate total cable
length, as shown in Figure 1.11. If the restriction is due to voltage reflection
and motor protection, tabular data is available. Refer to Appendix A for
exact distances allowed.

Important: For multi motor applications review the installation carefully.
Consult your distributor drive specialist or Rockwell
Automation directly, when considering a multi motor
application with greater than two motors. In general most
installations will have no issues. However high peak cable
charging currents can cause drive over-currents or ground
faults.
Cable for Discrete Drive I/O
Discrete I/O such as Start and Stop commands can be wired to the drive
using a variety of cabling. Shielded cable is recommended, as it can help
reduce cross-coupled noise from power cables. Standard individual
conductors that meet the general requirements for type, temperature, gauge
and applicable codes are acceptable if they are routed away from higher
voltage cables to minimize noise coupling. However, multi-conductor cable
may be less expensive to install. Control wires should be separated from
power wires by at least 0.3 meters (1 foot)

Cable
Always use shielded cable with copper wire. Wire with insulation rating of
300V or greater is recommended. Analog signal wires should be separated
from power wires by at least 0.3 meters (1 foot). It is recommended that
encoder cables be run in a separate conduit. If signal cables must cross
power cables, cross at right angles. Terminate the shield of the shielded
cable as recommended by manufacturer of the encoder or analog signal
device.

DeviceNet
DeviceNet cable options, topology, distances allowed and techniques used
are very specific to the DeviceNet network. Refer to DeviceNet Cable
System Planning and Installation Manual, publication DN-6.72.
In general, there are 4 acceptable cable types for DeviceNet media. These
include:
1. Round (Thick) cable with an outside diameter of 12.2 mm (0.48 in)
normally used for trunk lines but can also be used for drop lines
2. Round (Thin) cable with an outside diameter of 6.9 mm (0.27 in)
normally used for drop lines but may also be used for trunk lines
3. Flat cable normally used for trunk lines
4. KwikLink drop cable used only in KwikLink systems.

Round cable contains five wires: one twisted pair (red and black) for 24V
DC power, one twisted pair (blue and white) for signal and a drain wire
(bare).
Flat cable contains four wires: one pair (red and black) for 24V DC power
and one pair (blue and white) for signal.
Drop cable for KwikLink is a 4-wire unshielded gray cable.
The distance between points, installation of terminating resistors and
chosen baud rate all play a significant part in the installation. Again, refer to
the DeviceNet Cable System Planning and Installation Manual for detailed
specifics.
ControlNet
ControlNet cable options, topology, distances allowed and techniques used
are very specific to the ControlNet network. For more information refer to
ControlNet Coax Cable System Planning and Installation Manual,
publication 1786-6.2.1.
Depending on the environment at the installation site there are several types
of RG-6 quad shield cables that may be appropriate. The standard cable
recommended is A-B Cat # 1786-RG6, Quad Shield coax (Belden 3092A).
Country, state or local codes such as the U.S. NEC govern the installation.
For:
Light Industrial
Heavy Industrial
High/Low Temperature or Corrosive

• Standard PVC
• CM-CL2
• Lay-on Armored
• Light Interlocking Armor
• Plenum-FEP
• CMP-CL2P
• High Flex
• Flood Burial
The allowable length of segments and installation of terminating resistors
play a significant part in the installation. Again, refer to the ControlNet
Coax Cable System Planning and Installation Manual for detailed specifics.
Ethernet
The Ethernet communications interface wiring is very detailed as to the type
of cable, connectors and routing. Because of the amount of detail required
to bring Ethernet into the industrial environment, planning an installation
should be done by following all recommendations in the Ethernet/IP Media
Planning and Installation Guide, publication ENET-IN001.
In general, Ethernet systems consist of specific cable types (STP shielded
Cable or UTP unshielded cable) using RJ45 connectors that meet the IP67
standard and are appropriate for the environment. Cables should also meet
TIA/EIA standards at industrial temperatures.
Publication DRIVES-IN001I-EN-P
1-14
Wire/Cable Types
Shielded cable is always recommended when the installation may include
welding, electrostatic processes, drives over 10 HP, Motor Control Centers,
high power RF radiation or devices carrying current in excess of 100 Amps.
Shield handling and single point grounding, also discussed in this
document, play an extremely important role in the proper operation of
Ethernet installations.
Finally, there are distance and routing limitations published in detail.
Remote I/O and Data Highway Plus (DH+)
Only 1770-CD, Belden #9463 is tested and approved for Remote I/O and
DH+ installations.
The maximum cable length depends on the chosen baud rate:
Baud Rate
57.6 KBPS
115.2 KBPS
230.4 KBPS
Maximum Cable Length
3,048 m (10,000 ft.)
1524 m (5000 ft.)
762 m (2500 ft.)
All three connections (blue, shield and clear) must be connected at each
node.
Do not connect in star topology. Only two cables may be connected at any
wiring point. Use either series or daisy chain topology at all points.
Serial (RS232/485)
Standard practices for serial communications wiring should be followed.
Belden 3106A or equivalent is recommended for RS232. It contains one
twisted pair and 1 signal common. Recommended cable for RS485 is 2
twisted pair with each pair individually shielded.

Power Distribution
This chapter discusses different power distribution schemes and factors
which affect drive performance.
System Configurations
The type of transformer and the connection configuration feeding a drive
plays an important role in its performance and safety. The following is a
brief description of some of the more common configurations and a
discussion of their virtues and shortcomings.
Delta/Wye with Grounded Wye Neutral
Delta/Wye with Grounded Wye Neutral is the most common type of
distribution system. It provides a 30-degree phase shift. The grounded
neutral provides a direct path for common mode current caused by the drive
output (see Chapter 3 and Chapter 6).
Rockwell Automation strongly recommends the use of grounded neutral
systems for the following reasons:
– Controlled path for common mode noise current
– Consistent line to ground voltage reference, which minimizes
insulation stress
– Accommodation for system surge protection schemes
Publication DRIVES-IN001I-EN-P
2-2
Power Distribution
Delta/Delta with Grounded Leg
or Four-Wire Connected Secondary Delta
or
Delta/Delta with Grounded Leg or Four-Wire Connected Secondary Delta is
a common configuration with no phase shift between input and output. The
grounded center tap provides a direct path for common mode current caused
by the drive output.
Three-Phase Open Delta with Single-Phase Center Tapped
Three
Phase
Loads
Single Phase Loads
Single Phase Loads
Three-Phase Open Delta with Single-Phase Center Tapped is a
configuration providing a Three-Phase delta transformer with one side
tapped. This tap (the neutral) is connected to earth. The configuration is
called the antiphase grounded (neutral) system.
The open delta transformer connection is limited to 58% of the 240V,
single-phase transformer rating. Closing the delta with a third single-phase,
240V transformer allows full rating for the two single-phase, 240V
transformers. The phase leg opposite the midpoint has an elevated voltage
when compared to earth or neutral. The “hottest” high leg must be
positively identified throughout the electrical system. It should be the center
leg in any switch, motor control, three-phase panel board, etc. The NEC
requires orange color tape to identify this leg.
Publication DRIVES-IN001I-EN-P
Power Distribution
2-3
Ungrounded Secondary
Grounding the transformer secondary is essential to the safety of personnel
and safe operation of the drive. Leaving the secondary floating allows
dangerously high voltages between the chassis of the drive and the internal
power structure components. Exceeding the voltage rating of the drive’s
input MOV (Metal Oxide Varistor) protection devices could cause a
catastrophic failure. In all cases, the input power to the drive should be
referenced to ground.
If the system is ungrounded, other general precautions such as a system
level ground fault detector or system level line to ground suppressor may be
necessary or an isolation transformer must be considered with the secondary
of the transformer grounded. Refer to local codes regarding safety
requirements. Also refer to Surge Protection MOVs and Common Mode
Capacitors on page 2-17.
High Resistance Ground
Grounding the wye secondary neutral through a resistor is an acceptable
method of grounding. Under a short circuit secondary condition, any of the
output phases to ground will not exceed the normal line to line voltage. This
is within the rating of the MOV input protection devices on the drive. The
resistor is often used to detect ground current by monitoring the associated
voltage drop. Since high frequency ground current can flow through this
resistor, care should be taken to properly connect the drive motor leads
using the recommended cables and methods. In some cases, multiple drives
(that may have one or more internal references to ground) on one
transformer can produce a cumulative ground current that can trigger the
ground fault interrupt circuit. Refer to Surge Protection MOVs and
Common Mode Capacitors on page 2-17.

TN-S Five-Wire System
L1
L2
L3
PEN or N
PE
TN-S five-wire distribution systems are common throughout Europe, with
the exception of the United Kingdom and Germany. Leg to leg voltage
(commonly at 400V) powers three-phase loads. Leg to neutral voltage
(commonly at 230V) powers single-phase loads. Neutral is a current
conducting wire, and connects through a circuit breaker. The fifth wire is a
separate ground wire. There is a single connection between ground and
neutral, typically in the distribution system. There should be no connections
between ground and neutral within the system cabinets.
AC Line Voltage
In general all Allen-Bradley drives are tolerant to a wide swing of AC line
voltage. Check the individual specification for the drives you are installing.
Incoming voltage imbalances greater than 2% can cause large unequal
currents in a drive. An input line reactor may be necessary when line
voltage imbalances are greater than 2%.
Publication DRIVES-IN001I-EN-P
Power Distribution
AC Line Impedance
2-5
To prevent excess current that may damage drives during events such as line
disturbances or certain types of ground faults, drives should have a
minimum amount of impedance in front of them. In many installations, this
impedance comes from the supply transformer and the supply cables. In
certain cases, an additional transformer or reactor is recommended. If any of
the following conditions exist, serious consideration should be given to
adding impedance (line reactor or transformer) in front of the drive:
A. Installation site has switched power factor correction capacitors.
B. Installation site has lightning strikes or voltage spikes in excess of
6000V Peak.
C. Installation site has power interruptions or voltage dips in excess of
200VAC.
D. The transformer is too large in comparison to the drive. See impedance
recommendation tables Table 2.A on page 7 through Table 2.H on
page 13 that are specific to each drive. Using these tables will allow the
largest transformer size for each product and rating based on
specific differences in construction, and is the preferred method to
follow.
Otherwise, use one of the two following more conservative methods:
1. For drives without built-in inductors, add line impedance whenever the
transformer kVA is more than 10 times larger than the drive kVA, or the
percent source impedance relative to each drive is less than 0.5%.
2. For drives with built-in inductors, add line impedance whenever the
transformer kVA is more than 20 times larger than the drive kVA, or the
percent source impedance relative to each drive is less than 0.25%.
To identify drives with built-in inductors, see the product specific tables.
The shaded rows identify products ratings without built-in inductors.
Use the following equations to calculate the impedance of the drive and
transformer:

0.05) for the formula.
Z xfmr 0.2304

0.22% is less than 0.5%. Therefore, this transformer is too big for the drive
and a line reactor should be added.

Note: Grouping multiple drives on one reactor is acceptable; however, the
reactor percent impedance must be large enough when evaluated for each
drive separately, not evaluated for all loads connected at once.
These recommendations are merely advisory and may not address all
situations. Site specific conditions must be considered to assure a quality
installation.

Multi-Drive Protection
Multiple drives on a common power line should each have their own line
reactor. Individual line reactors provide filtering between each drive to
provide optimum surge protection for each drive. However, if it is
necessary to group more than one drive on a single AC line reactor, use the
following process to verify that the AC line reactor provides a minimum
amount of impedance:
1. In general, up to 5 drives can be grouped on one reactor.
2. Add the input currents of the drives in the group.
3. Multiply that sum by 125%.
4. Use publication 1321-2.0 to select a reactor with a maximum continuous
current rating greater than the multiplied current.
5. Verify that the impedance of the selected reactor is more than 0.5%
(0.25% for drives with internal inductors) of the smallest drive in the group
by using the formulas below. If the impedance is too small, select a reactor
with a larger inductance and same amperage, or regroup the drives into
smaller groups and start over.
Z drive =
Vline - line
3 * I input - rating
Z reactor = L * 2 * 3.14 * f
L is the inductance of the reactor in henries and f is the AC line frequency
Publication DRIVES-IN001I-EN-P
2-16
Power Distribution
Example: There are 5 drives, each is rated 1 HP, 480V, 2.7 amps. These drives do
not have internal inductors.
Total current = 5 * 2.7 amps = 13.5 amps
125% * Total current = 125% * 13.5 amps = 16.9 amps
From publication 1321-2.0, we selected the reactor 1321-3R12-C, which
has a maximum continuous current rating of 18 amps and an inductance of
4.2 mH (0.0042 henries).
Z drive =
Vline - line
3 * I input - rating
=
480
3 * 2.7
= 102.6 Ohms
Z reactor = L * (2 * 3.14) * f = 0.0042 * 6.28 * 60 = 1.58 Ohms
Z reactor
1.58
=
= 0.0154 = 1.54%
Z drive
102.6
1.54% is more than the 0.5% impedance recommended. The 1321-3R12-C
can be used for the (5) 2.7 amp drives in this example.

Surge Protection MOVs and
Common Mode Capacitors
!
2-17
ATTENTION: When installing a drive on an ungrounded,
high-resistance or B phase grounded distribution system,
disconnect the phase-to-ground MOV circuit and the common
mode capacitors from ground.
Note: In some drives, a single jumper connects both the phase-to-ground
MOV and the common mode capacitors to ground.
MOV Circuitry
Most drives are designed to operate on three-phase supply systems with
symmetrical line voltages. To meet IEEE 587, these drives are equipped
with MOVs that provide voltage surge protection as well as phase-to-phase
and phase-to-ground protection. The MOV circuit is designed for surge
suppression (transient line protection) only, not for continuous operation.

With ungrounded distribution systems, the phase-to-ground MOV
connection can become a continuous current path to ground. Exceeding the
published phase-to-phase, phase-to-ground voltage or energy ratings may
cause physical damage to the MOV.
Suitable isolation is required for the drive when there is potential for
abnormally high phase-to-ground voltages (in excess of 125% of nominal
line-to-line voltage), or when the supply ground is tied to another system or
equipment that could cause the ground potential to vary with operation. An
isolation transformer is strongly recommended when this condition exists.
Common Mode Capacitors
Many drives also contain common mode capacitors that are referenced to
ground. In installations with ungrounded or high resistive ground systems,
the common mode capacitors can capture high frequency common mode or
ground fault currents. This can cause bus overvoltage conditions, which
could lead to damage or drive faults. Systems which are ungrounded or have
one phase grounded (commonly called B phase grounded) apply higher than
normal voltage stresses directly to the common mode capacitors, which can
lead to shortened drive life or damage.

Using PowerFlex Drives with
Regenerative Units
!
DC Bus Wiring Guidelines
ATTENTION: If a Regenerative unit (i.e. 1336 REGEN) or
other Active Front End (AFE) is used as a bus supply or brake,
the common mode capacitors should be disconnected as
described in the Drive User Manual. This will guard against
possible equipment damage.
DC bus wiring refers to connecting the DC bus of an AC drive to the DC
connections on another piece of equipment. That equipment could include
any or all of the following:
•
•
•
•
•
•
Additional AC drive
Non-Regenerative DC Bus Supply
Regenerative DC Bus Supply
Regenerative Braking Module
Dynamic Braking Module
Chopper Module
For further information on the types of common DC bus configurations and
applications refer to AC Drives in Common Bus Configurations (publication
DRIVES-AT002).
Drive Line-up
Generally, it is desirable to have the drive line-up match the machine layout.
However, if there is a mix of drive frame sizes used in the line-up, the
general system layout should have the largest drives located closest to the
rectifier source. The rectifier source need not be at the left end of the system
line-up. Many times it is advantageous to put the rectifier in the middle of
the line-up, minimizing the distances to the farthest loads. This is needed to
minimize the energy stored in the parasitic inductance of the bus structure
and thus lower peak bus voltages during transient operation.
The system must be contained in one contiguous line-up. The bus cannot be
interrupted to go to another cabinet for the remainder of the system drives.
This is needed to maintain low inductance.
DC Bus Connections
General
The interconnection of drives to the DC bus, and the inductance levels
between the drives, should be kept to a minimum for reliable system
operation. Therefore, a low inductance-type DC bus should be used, 0.35
µH/m or less.
The DC bus connections should not be “daisy chained.” Configuration of
the DC bus connections should be in a “star” configuration to allow for
proper fusing.

Bus Bar vs. Cable
• DC Bus Bar is recommended.
• When DC Bus Bar cannot be used, use the following guidelines for DC
Bus cables:
– Cable should be twisted where possible, approximately 1 twist per
inch.
– Cable rated for the equivalent AC voltage rating should be used. The
peak AC voltage is equivalent to the DC voltage. For example, the
peak AC voltage on a 480V AC system no load is 480 x 1.414 = 679
Volts peak. The 679 Volts peak corresponds to 679 Volts DC at no
load.
Publication DRIVES-IN001I-EN-P
2-20
Power Distribution
Braking Chopper
Connection of the brake unit should be closest to the largest drive. If all are
the same rating, then closest to the drive that regenerates the most.
In general, brake units should be mounted within 3 meters (10 feet) of the
drive. Resistors for use with chopper modules must be located within 30
meters (100 feet) of the chopper module. Refer to the respective braking
product documentation for details.
An RC snubber circuit is required when using the 1336-WA, WB or WC
Brake Chopper in the configurations listed below:
1. A non-regenerative bus supply configuration using a PowerFlex Diode
Bus Supply.
2. A shared AC/DC Bus configuration containing a PowerFlex 700/700S
Frame 0-4 drive or PowerFlex 40P drive.
3. A shared DC Bus (Piggy Back) configuration when the main drive is a
PowerFlex 700/700S Frame 0 to 4 or PowerFlex 40P drive.
The RC snubber circuit is required to prevent the DC bus voltage from
exceeding the 1200V maximum Brake Chopper IGBT voltage. The 1336
Brake Chopper power-up delay time is 80 milliseconds. During this time,
the IGBT will not turn on. The RC snubber circuit must always be
connected to the DC bus (located close to the braking chopper) to absorb the
power-on voltage overshoot (see Figure 2.3).
The specifications for the RC snubber are:
R = 10 ohm, 100 W, low inductance (less than 50 µH)
C = 20 µF, 2000V

connected to earth through a ground connection or connections of
sufficiently low impedance and having sufficient current-carrying capacity
to prevent the buildup of voltages which may result in undue hazard to
connected equipment or to persons” (as defined by the US National Electric
Code NFPA70, Article 100B). Grounding of a drive or drive system is done
for 2 basic reasons: safety (defined above) and noise containment or
reduction. While the safety ground scheme and the noise current return
circuit may sometimes share the same path and components, they should be
considered different circuits with different requirements.
Grounding Safety Grounds
The object of safety grounding is to ensure that all metalwork is at the same
ground (or Earth) potential at power frequencies. Impedance between the
drive and the building scheme ground must conform to the requirements of
national and local industrial safety regulations or electrical codes. These
will vary based on country, type of distribution system and other factors.
Periodically check the integrity of all ground connections.
General safety dictates that all metal parts are connected to earth with
separate copper wire or wires of the appropriate gauge. Most equipment has
specific provisions to connect a safety ground or PE (protective earth)
directly to it.
Building Steel
If intentionally bonded at the service entrance, the incoming supply neutral
or ground will be bonded to the building ground. Building steel is judged to
be the best representation of ground or earth. The structural steel of a
building is generally bonded together to provide a consistent ground
potential. If other means of grounding are used, such as ground rods, the
user should understand the voltage potential, between ground rods in
different areas of the installation. Type of soil, ground water level and other
environmental factors can greatly affect the voltage potential between
ground points if they are not bonded to each other.
Publication DRIVES-IN001I-EN-P
3-2
Grounding
Grounding PE or Ground
The drive safety ground - PE must be connected to scheme or earth ground.
This is the safety ground for the drive that is required by code. This point
must be connected to adjacent building steel (girder, joist), a floor ground
rod, bus bar or building ground grid. Grounding points must comply with
national and local industrial safety regulations or electrical codes. Some
codes may require redundant ground paths and periodic examination of
connection integrity. Global Drive Systems requires the PE ground to be
connected to the transformer ground feeding the drive system.
RFI Filter Grounding
Using an optional RFI filter may result in relatively high ground leakage
currents. Therefore, the filter must only be used in installations with
grounded AC supply systems and be permanently installed and solidly
grounded to the building power distribution ground. Ensure the incoming
supply neutral is solidly connected to the same building power distribution
ground. Grounding must not rely on flexible cables or any plug or socket
that may be accidentally disconnected. Some codes may require redundant
ground connections. Periodically check the integrity of all connections.
Refer to the instructions supplied with the filter.
Grounding Motors
The motor frame or stator core must be connected directly to the drive PE
connection with a separate ground conductor. It is recommended that each
motor frame be grounded to building steel at the motor. Refer to Cable
Trays in Chapter 4 for more information.
Grounding and TN-S Five-Wire Systems
Do not connect ground to neutral within a system cabinet, when using a
TN-S five-wire distribution system. The neutral wire is a current conducting
wire. There is a single connection between ground and neutral, typically in
the distribution system.
TN-S five-wire distribution systems are common throughout Europe, with
the exception of the United Kingdom and Germany. Leg to leg voltage
(commonly at 400V) powers three-phase loads. Leg to neutral voltage
(commonly at 230V) powers single-phase loads.

Grounding
The grounding scheme can greatly affect the amount of noise and its impact
on sensitive equipment. The power scheme is likely to be one of three types:
• Ungrounded Scheme
• Scheme with High Resistance Ground
• Fully Grounded Scheme
An ungrounded scheme, as shown in Figure 3.2, does not provide a direct
path for the common mode noise current, causing it to seek other
uncontrolled paths. This causes related noise issues.
Figure 3.2 Ungrounded Scheme
Earth Ground Potential
A scheme with a high resistance ground, shown in Figure 3.3, provides a
direct path for common mode noise current, like a fully grounded scheme.
Designers, who are concerned with minimizing ground fault currents,
commonly choose high resistance ground schemes.
Figure 3.3 Scheme with High Resistance Ground
Earth Ground Potential
A fully grounded scheme, shown in Figure 3.4, provides a direct path for
common mode noise currents. The use of grounded neutral systems is
recommended for the following reasons:
– Controlled path for common mode noise current
– Consistent line to ground voltage reference, which minimizes
insulation stress
– Accommodation for system surge protection schemes
Publication DRIVES-IN001I-EN-P
Grounding
3-5
Figure 3.4 Fully Grounded Scheme
Earth Ground Potential
The installation and grounding practices to reduce common mode noise
issues can be categorized into three ratings. The scheme used must weigh
additional costs against the operating integrity of all scheme components. If
no sensitive equipment is present and noise is not be an issue, the added cost
of shielded cable and other components may not be justified.
Acceptable Grounding Practices
The scheme shown below is an acceptable ground layout for a single drive
installation. However, conduit may not offer the lowest impedance path for
any high frequency noise. If the conduit is mounted so that it contacts the
building steel, it is likely that the building steel will offer a lower impedance
path and allow noise to inhabit the ground grid.

Cable Shields
Motor and Input Cables
Shields of motor and input cables must be bonded at both ends to provide a
continuous path for common mode noise current.
Control and Signal Cables
Shields of control cables should be connected at one end only. The other
end should be cut back and insulated.
– The shield for a cable from one cabinet to another must be connected
at the cabinet that contains the signal source.
– The shield for a cable from a cabinet to an external device must be
connected at the cabinet end, unless specified by the manufacturer of
the external device.
Never connect a shield to the common side of a logic circuit (this will
introduce noise into the logic circuit). Connect the shield directly to a
chassis ground.
Shield Splicing
Figure 3.5 Spliced Cable Using Shieldhead Connector
PE
If the shielded cable needs to be stripped, it should be
stripped back as little as possible to ensure that continuity
of the shield is not interrupted. Avoid splicing motor
power cables when ever possible. Ideally, motor cables
should run continuously between the drive and motor
terminals. The most common reason for interrupted cable/
shield is to incorporate an “at the motor” disconnect
switch. In these cases, the preferred method of splicing is
to use fully shielded bulkhead connectors.
Single Point
A single safety ground point or ground bus bar should be
directly connected to the building steel for cabinet
installations. All circuits including the AC input ground
conductor should be grounded independently and directly
to this point/bar.
Isolated Inputs
If the drive’s analog inputs are from isolated devices and the output signal is
not referenced to the ground, the drive’s inputs do not need to be isolated.
An isolated input is recommended to reduce the possibility of induced noise
if the transducer’s signal is referenced to ground and the ground potentials
are varied (Refer to Noise Related Grounds on page 3-3). An external
isolator can be installed if the drive does not provide input isolation.

Safety Guidelines
Grounding to the Component Mounting Panel
In the example below, the drive chassis ground plane is extended to the
mounting panel. The panel is made of zinc-plated steel to ensure a proper
bond between chassis and panel.
Figure 4.1 Drive Chassis Ground Plane Extended to the Panel
Drive ground plane
(chassis) bonded to panel
Note: Where TE and PE terminals are provided, ground each separately to
the nearest point on the panel using flat braid.
In an industrial control cabinet, the equivalent to the copper ground layer of
a PCB is the mounting panel. To make use of the panel as a ground plane it
should be made of zinc-plated mild steel. If painted, remove the paint at
each mounting and grounding point.
Publication DRIVES-IN001I-EN-P
4-2
Practices
Zinc-plated steel is strongly recommended due to its inherent ability to bond
with the drive chassis and resist corrosion. The disadvantage with painted
panels, apart from the cost in labor to remove the paint, is the difficulty in
making quality control checks to verify if the paint has been properly
removed, and any future corrosion of the unprotected mild steel may
compromise noise performance.
Plain stainless steel panels are also acceptable but are inferior to zinc-plated
mild steel due to their higher ohms-per-square resistance.
Though not always applicable, a plated cabinet frame is also highly
desirable since it makes a high frequency bond between panel and cabinet
sections more reliable.
Doors
For doors 2 m (78 in.) in height, ground the door to the cabinet with two or
three braided straps.
EMC seals are not normally required for industrial systems.
EMC Specific Installations
A steel enclosure is recommended. A steel enclosure can help guard against
radiated noise to meet EMC standards. If the enclosure door has a viewing
window, it should be a laminated screen or a conductive optical substrate to
block EMC.
Do not rely on the hinge for electrical contact between the door and the
enclosure - install a grounding wire. For doors 2 m (78 in.) in height, two or
three braided grounding straps between the door and the cabinet should be
used. EMC gaskets are not normally required for industrial systems.
Layout
Plan the cabinet layout so that drives are separated from sensitive
equipment. Choose conduit entry points that allow any common mode noise
to remain away from PLCs and other equipment that may be susceptible to
noise. Refer to Moisture on page 4-18 for additional information.

additional washers as shims so that the chassis does not bend when you
tighten the nuts.
Conduit Entry
Entry Plates
In most cases, the conduit entry plate will be a paint-free conductive
material. The surface of the plate should be clean of oil or contaminants. If
the plate is painted, use a connector that cuts through the paint and makes a
high quality connection to the plate material
Or
Remove the paint around the holes to the bare metal one inch in from the
edge of the plate. Grind down the paint on the top and bottom surfaces. Use
a high quality joint compound when reassembling to avoid corrosion.

Cable Connectors/Glands
Choose cable connectors or glands that offer the best cable protection,
shield termination and ground contact. Refer to Shield Termination on
page 4-15 for more information.
Shield terminating connectors
The cable connector selected must provide good 360o contact and low
transfer impedance from the shield or armor of the cable to the conduit entry
plate at both the motor and the drive or drive cabinet for electrical bonding.
SKINTOP® MS-SC/MS-SCL cable grounding connectors and NPT/PG
adapters from LAPPUSA are good examples of this type of shield
terminating gland.

Pigtail termination is the least effective method of noise containment.
It is not recommended if:
• the cable length is greater than 1 m (39 in.) or extends beyond the panel
• in very noisy areas
• the cables are for very noise sensitive signals (for example, registration
or encoder cables)
• strain relief is required
If a pigtail is used, pull and twist the exposed shield after separation from
the conductors. Solder a flying lead to the braid to extend its length.
Ground Connections
Ground conductors should be connected with care to assure safe and
adequate connections.
For individual ground connections, star washers and ring lugs should be
used to make connections to mounting plates or other flat surfaces that do
not provide proper compression lugs.
If a ground bus system is used in a cabinet, follow the bus bar mounting
diagrams.

Within A Cabinet
When multiple equipment is mounted in a common enclosure, group the
input and output conduit/armor to one side of the cabinet as shown in Figure

susceptible equipment cabling to the opposite side will minimize many
effects of drive induced noise currents.

Common mode noise current returning on the output conduit, shielding or
armor can flow into the cabinet bond and most likely exit through the
adjacent input conduit/armor bond near the cabinet top, well away from
sensitive equipment (such as the PLC). Common mode current on the return
ground wire from the motor will flow to the copper PE bus and back up the
input PE ground wire, also away from sensitive equipment (Refer to Proper
Cabinet Ground - Drives & Susceptible Equipment on page 4-12). If a
cabinet PE ground wire is run it should be connected from the same side of
the cabinet as the conduit/armor connections. This keeps the common mode
noise shunted away from the PLC backplane.

Conduit
Good Solution
Better Solution
Magnetic steel conduit is preferred. This type of conduit provides the best
magnetic shielding. However not all applications allow the use of magnetic
steel conduit. Stainless steel or PVC may be required. Conduit other than
magnetic steel will not provide the same level of shielding for magnetic
fields induced by the motor and input power currents.
Conduit must be installed so as to provide a continuous electrical path
through the conduit itself. This path can become important in the
containment of high frequency noise.
To avoid nicking, use caution when pulling the wire. Insulation damage can
occur when nylon coated wiring such as THHN or THWN is pulled through
conduit, particularly 90°bends. Nicking can significantly reduce or remove
the insulation. Use great care when pulling nylon coated. Do not use water
based lubricants with nylon coated wire such as THHN.
Do not route more than 3 sets of motor cables in one conduit. Maintain the
proper fill rates per the applicable electrical codes.
Do not rely on the conduit as the ground return for a short circuit. Route a
separate ground wire inside the conduit with the motor or input power
wires.

Practices
Cable Trays
When laying cable in cable trays, do not randomly distribute them. Power
cables for each drive should be bundled together and anchored to the tray. A
minimum separation of one cable width should be maintained between
bundles to reduce overheating and cross-coupling. Current flowing in one
set of cables can induce a hazardous voltage and/or excessive noise on the
cable set of another drive, even when no power is applied to the second
drive.

Carefully arrange the geometry of multiple cable sets. Keep conductors
within each group bundled. Arrange the order of the conductors to minimize
the current which induced between sets and to balance the currents. This is
critical on drives with power ratings of 200 HP (150 kW) and higher.
Maintain separation between power and control cables. When laying out
cable tray for large drives make sure that cable tray or conduit containing
signal wiring is separated from the conduit or trays containing power or
motor wiring by 3 feet or more. Electromagnetic fields from power or motor
currents can induce currents in the signal cables. Dividers also provide
excellent separation.

Refer to Shield Splicing on page 3-7 to splice shielded cables. The
following methods are acceptable if the shield connection to the ground is
not accomplished by the gland or connector. Refer to the table associated
with each type of clamp for advantages and disadvantages.
Termination via circular clamp
Clamp the cable to the main panel closest to the shield terminal using the
circular section clamping method. The preferred method for grounding
cable shields is clamping the circular section of 360°bonding, as shown in
Figure 4.13. It has the advantage of covering a wide variety of cable
diameters and drilling/mounting is not required. Its disadvantages are cost
and availability in all areas.
Figure 4.13 Commercial Cable Clamp (Heavy Duty)
Plain copper saddle clamps, as shown in Figure 4.14, are sold in many areas
for plumbing purposes, but are very effective and available in a range of
sizes. They are low cost and offer good strain relief as well. You must drill

The cable connector selected must provide good 360° contact and low
transfer impedance from the shield or armor of the cable to the conduit entry
plate at both the motor and the drive or drive cabinet for electrical bonding.

Practices
Conductor Termination
Terminate power, motor and control connections to the drive terminal
blocks. User manuals list minimum and maximum wire gauges, tightening
torque for terminals and recommended lug types if stud connections are
provided. Use a connector with 3 ground bushings when using a cable with
3 ground conductors. Bending radii minimums per the applicable electrical
code should be followed.
Power TB
Power terminals are normally fixed (non-pull apart) and can be cage
clamps, barrier strips or studs for ring type crimp lugs depending on the
drive style and rating. Cage clamp styles may require a non-standard
screwdriver. Crimp lugs will require a crimping tool. On smaller sizes, a
stripping gauge may be provided on the drive to assist in the amount of
insulation to remove. Normally the three phase input is not phase sensitive.
That is, the sequence of A,B,C phases has no effect on the operation of the
drive or the direction of motor rotation.
Control TB
Control terminal blocks are either pull apart or fixed (non pull apart).
Terminals will be either spring clamp type or barrier strip. A stripping
gauge may be provided on the drive to assist in the amount of insulation to
remove. Some control connections, such as analog input and output signals,
are polarity sensitive. Consult the applicable user manual for correct
connection.
Signal TB
If an encoder or tachometer feedback is used, a separate terminal block or
blocks may be provided. Consult the user manual for these phase sensitive
connections. Improper wiring could lead to incorrect drive operation.
Cables terminated here are typically shielded and the signals being carried
are generally more sensitive to noise. Carefully check the user manual for
recommendations on shield termination. Some shields can be terminated at
the terminal block and others will be terminated at the entry point.

Belden 29500 style cable is a PVC jacketed, shielded type TC with XLPE

Automation research, tests have determined this cable is notably superior to
loose wires in dry, damp and wet applications and can significantly reduce
capacitive coupling and common mode noise. Other cable types for wet

Reflected Wave
This chapter discusses the reflected wave phenomenon and its impact on
drive systems.
Description
The inverter section of a drive does not produce sinusoidal voltage, but
rather a series of voltage pulses created from the DC bus. These pulses
travel down the motor cables to the motor. The pulses are then reflected
back to the drive. The reflection is dependent on the rise time of the drive
output voltage, cable characteristics, cable length and motor impedance. If
the voltage reflection is combined with another, subsequent pulse, peak
voltages can be at a destructive level. A single IGBT drive output may have
reflected wave transient voltage stresses of up to twice (2 pu or per unit) the
DC bus voltage between its own output wires. Multiple drive output wires in
a single conduit or wire tray further increase output wire voltage stress
between multi-drive output wires that are touching. Drive #1 may have a (+)
2 pu stress while drive #2 may simultaneously have a (-) 2 pu stress.
Effects On Wire Types
Wires with dielectric constants greater than 4 cause the voltage stress to
shift to the air gap between the wires that are barely touching. This electric
field may be high enough to ionize the air surrounding the wire insulation
and cause a partial discharge mechanism (corona) to occur. The electric
field distribution between wires increases the possibility for corona and
greater ozone production. This ozone attacks the PVC insulation and
produces carbon tracking, leading to the possibility of insulation
breakdown.
Based on field and internal testing, Rockwell Automation/Allen-Bradley
has determined conductors manufactured with Poly-Vinyl Chloride (PVC)
wire insulation are subject to a variety of manufacturing inconsistencies
which can lead to premature insulation degradation when used with IGBT
drives. Flame-retardant heat-resistant thermoplastic insulation is the type of
insulation listed in the NEC code for the THHN wire designation. This type
of insulation is commonly referred to as PVC. In addition to manufacturing
inconsistencies, the physical properties of the cable can change due to
environment, installation and operation, which can also lead to premature
insulation degradation. The following is a summary of our findings:
Due to inconsistencies in manufacturing processes or wire pulling, air voids
can also occur in the THHN wire between the nylon jacket and PVC
insulation. Because the dielectric constant of air is much lower than the
dielectric constant of the insulating material, the transient reflected wave
voltage might appear across these voids. If the corona inception voltage
Publication DRIVES-IN001I-EN-P
5-2
Reflected Wave
(CIV) for the air void is reached, ozone is produced. Ozone attacks the PVC
insulation leading to a breakdown in cable insulation.
Asymmetrical construction of the insulation has also been observed for
some manufacturers of PVC wire. A wire with a 15 mil specification was
observed to have an insulation thickness of 10 mil at some points. The
smaller the insulation thickness, the less voltage the wire can withstand.
THHN jacket material has a relatively brittle nylon that lends itself to
damage (i.e. nicks and cuts) when pulled through conduit on long wire runs.
This issue is of even greater concern when the wire is being pulled through
multiple 90°bends in the conduit. These nicks may be a starting point for
CIV leading to insulation degradation.
During operation, the conductor heats up and a “coldflow” condition may
occur with PVC insulation at points where the unsupported weight of the
wire may stretch the insulation. This has been observed at 90°bends where
wire is dropped down to equipment from an above wireway. This
“coldflow” condition produces thin spots in the insulation which lowers the
cable's voltage withstand capability.
Refer to NEC Article 100 for definitions of Damp, Dry and Wet locations.
The U.S. NEC permits the use of heat-resistant thermoplastic wire in both
dry and damp applications (Table 310-13). However, PVC insulation
material is more susceptible to absorbing moisture than XLPE (Cross
Linked polyethylene) insulation material (XHHN-2) identified for use in
wet locations. Because the PVC insulating material absorbs moisture, the
Corona Inception Voltage insulation capability of the “damp” or “wet”
THHN was found to be less than ½ of the same wire when “dry.” For this
reason, certain industries where water is prevalent in the environment have
refrained from using THHN wire with IGBT drives. Rockwell Automation
strongly suggests the use of XLPE insulation for wet areas.
Length Restrictions For
Motor Protection
To protect the motor from reflected waves, limit the length of the motor
cables from the drive to the motor. Each drive's user manual lists the lead
length limitations based on drive size and the quality of the insulation
system in the chosen motor.
If the distance between drive and motor must exceed these limits, contact
the local office or factory for analysis and advice. Refer to Appendix A for
complete tables.

Electromagnetic Interference
This chapter discusses types of electromagnetic interference and its impact
on drive systems.
What Causes Common
Mode Noise
Faster output dv/dt transitions of IGBT drives increase the possibility for
increased Common Mode (CM) electrical noise. Common Mode Noise is a
type of electrical noise induced on signals with respect to ground.

Path for Common
Mode Current
There is a possibility for electrical noise from drive operation to interfere
with adjacent sensitive electronic equipment, especially in areas where
many drives are concentrated. Generating common mode currents by
varying frequency inverters is similar to the common mode currents that
occur with DC drives. Although AC drives produce a much higher
frequency then DC drives (250 kHz - 6MHz). Inverters have a greater
potential for exciting circuit resonance because of very fast turn on switches
causing common mode currents to look for the lowest impedance path back
to the inverter. The dv/dt and di/dt from the circulating ground currents can
couple into the signal and logic circuits, causing improper operation and
possible circuit damage. When conventional grounding techniques do not
work you must use high frequency bonding techniques. If installers do not
use these techniques, motor bearing currents increase and system circuit
boards have the potential to fail prematurely. Currents in the ground system
may cause problems with computer systems and distributed control
systems.
Publication DRIVES-IN001I-EN-P
6-2
Electromagnetic Interference
Containing Common Mode
Noise With Cabling
Cable type has a great effect on the ability to contain common mode noise
in a system that incorporates a drive.
Conduit
The combination of a ground conductor and conduit contains most
capacitive current and returns it to the drive without polluting the ground
grid. A conduit may still have unintended contact with grid ground structure
due to straps, support, etc. The AC resistance characteristics of earth are
generally variable and unpredictable, making it difficult to predict how
noise current will divide between wire, conduit or the ground grid.
Shielded or Armored Power Cable
The predominant return path for common mode noise is the shield/armor
itself when using shielded or armored power cables. Unlike conduit, the
shield/armor is isolated from accidental contact with grounds by a PVC
outer coating. Making the majority of noise current flow in the controlled
path and very little high frequency noise flows into the ground grid.
Noise current returning on the shield or safety ground wire is routed to the
drive PE terminal, down to the cabinet PE ground bus, and then directly to
the grounded neutral of the drive source transformer. Take care when
bonding the armor or shield to the drive PE. A low impedance cable or strap
is recommended when making this connection, as opposed to the smaller
gauge ground wire either supplied as part of the motor cable or supplied
separately. Otherwise, the higher frequencies associated with the common
mode noise will find this cable impedance higher and look for a lower
impedance path. The cable’s radiated emissions are minimal because the
armor completely covers the noisy power wires. Also, the armor prevents
EMI coupling to other signal cables that might be routed in the same cable
tray.
Another effective method of reducing common mode noise is to attenuate it
before it can reach the ground grid. Installing a common mode ferrite core
on the output cables can reduce the amplitude of the noise to a level that
makes it relatively harmless to sensitive equipment or circuits. Common
mode cores are most effective when multiple drives are located in a
relatively small area. For more information see the 1321-M Common Mode
Chokes Instructions, publication 1321-5.0.
As a general rule:
IF the distance between the drive and motor or the distance between drive
and input transformer is greater than 75 feet.
AND
IF sensitive circuits with leads greater then 75 feet such as: encoders,
analog, or capacitive sensors are routed, in or out of the cabinet, near the
drive or transformer
THEN
Common mode chokes should be installed.

How Electromechanical
Switches Cause Transient
Interference
6-3
Electromechanical contacts cause transient interference when switching
inductive loads such as relays, solenoids, motor starters, or motors. Drives,
as well as other devices having electronic logic circuits, are susceptible to
this type of interference.
Examine the following circuit model for a switch controlling an inductive
load. Both the load and the wiring have inductance, which prevents the
current from stopping instantly when the switch contacts open. There is also
stray capacitance in the wiring.
VC
Wiring
Capacitance
Power
Load
Inductance
Load
Wiring Inductance
Interference occurs when the switch opens while it is carrying current. Load
and cable inductance prevents the current from immediately stopping. The
current continues to flow, and charges the capacitance in the circuit. The
voltage across the switch contacts (VC) rises, as the capacitance charges.
This voltage can reach very high levels. When the voltage exceeds the
breakdown voltage for the space between the contacts, an arc occurs and the
voltage returns to zero. Charging and arcing continues until the distance
between the contacts is sufficient to provide insulation. The arcing radiates
noise at an energy levels and frequencies that disturb logic and
communication circuits.
If the power source is periodic (like AC power), you can reduce the
interference by opening the contact when the current waveform crosses
zero. Opening the circuit farther from zero elevates the energy level and
creates more interference.
How to Prevent or Mitigate The most effective way to avoid this type of transient interference, is to use
Transient Interference from a device like an Allen-Bradley Bulletin 156 contactor to switch inductive
Electromechanical Switches AC loads. These devices feature “zero cross” switching.

A common method for mitigating transient interference is to put a diode in
parallel with an inductive DC load or a suppressor in parallel with an

withstand the voltage, power and frequency of switching for your
application. These methods are not totally effective, because they do not
entirely eliminate arcing at the contacts.

The application of pulse-width modulated (PWM) inverters has led to
significant advantages in terms of the performance, size, and efficiency of
variable speed motor controls. However, the high switching rates used to
obtain these advantages can also contribute to motor bearing damage due to
bearing currents and Electric Discharge Machining (EDM). Bearing
damage on motors supplied by PWM inverters is more likely to occur in
applications where the coupling between the motor and load is not
electrically conductive (such as belted loads), when the motor is lightly
loaded, or when the motor is in an environment with ionized air. Other
factors, such as the type of grease and the type of bearings used may also
affect the longevity of motor bearings. Motor manufacturers that design and
manufacture motors for use with variable frequency drives can offer
solutions to help mitigate these potential problems.

Motor Cable Length Restrictions Tables
The distances listed in each table are valid only for specific cable
constructions and may not be accurate for lesser cable designs, particularly
if the length restriction is due to cable charging current (indicated in tables
by shading). When choosing the proper cable, note the following
definitions:
Unshielded Cable
• Tray cable - fixed geometry without foil or braided shield but including an exterior cover
• Individual wires not routed in metallic conduit
Shielded Cable
•
•
•
•
Individual conductors routed in metallic conduit
Fixed geometry cables with foil or braided shield of at least 75% coverage
Belden 295xx or Alcatel C1202 needed, as indicated by individual table for specific drive
Continuous weld or interlocked armored cables with no twist in the conductors (may
have and optional foil shield)
Important: Certain shielded cable constructions may cause excessive cable charging
currents and may interfere with proper application performance, particularly
on smaller drive ratings. Shielded cables that do not maintain a fixed
geometry, but rather twist the conductors and tightly wrap the bundle with a
foil shield may cause unnecessary drive tripping. Unless specifically stated in
the table, the distances listed ARE NOT applicable to this type of cable.
Actual distances for this cable type may be considerably less.

Frame 12 drives have dual inverters and require two output reactors. The resistor ratings are per phase values for each reactor.
Some Frame 13 drives require two output reactors to match drive amp rating. The resistor ratings are per phase values for each reactor.
Resistor specification is based on two cables per phase.
Resistor specification is based on three cables per phase.
Resistor specification is based on four cables per phase.

Frame 12 drives have dual inverters and require two output reactors. The resistor ratings are per phase values for each reactor.
Some Frame 13 drives require two output reactors to match drive amp rating. The resistor ratings are per phase values for each reactor.
Resistor specification is based on two cables per phase.
Resistor specification is based on three cables per phase.
Resistor specification is based on four cables per phase.

Drive
Frame 12 drives have dual inverters and require two output reactors. The resistor ratings are per phase values for each reactor.
Some Frame 13 drives require two output reactors to match drive amp rating. The resistor ratings are per phase values for each reactor.
Resistor specification is based on two cables per phase.
Resistor specification is based on three cables per phase.
Resistor specification is based on four cables per phase.

Motor Cable Length Restrictions Tables
1336 PLUS II and IMPACT
To increase the distance between the drive and the motor, some device
(RWR or Terminator) needs to be added to the system. Shaded distances are
restricted by cable capacitance charging current.

Values shown are for nominal input voltage, drive carrier frequency of 2 kHz or as shown and surrounding air temperature at the motor of 40o C. Consult factory
regarding operation at carrier frequencies above 2 kHz. Multiply values by 0.85 for high line conditions. For input voltages of 380, 400 or 415V AC, multiply the table
values by 1.25, 1.20 or 1.15, respectively.
These distance restrictions are due to charging of cable capacitance and may vary from application to application.
Includes wire in conduit. Shielded cable is Belden 295xx or equivalent.
A 3% reactor reduces motor and cable stress but may cause a degradation of motor waveform quality. Reactors must have a turn-turn insulation rating of 2100 Volts
or higher.

Values shown are for nominal input voltage and drive carrier frequency of 2 kHz. Consult factory regarding operation at carrier frequencies above 2 kHz.
When used on 600V systems, 1329R/L motors have a corona inception voltage rating of approximately 1850V.
A 3% reactor reduces motor and cable stress but may cause a degradation of motor waveform quality. Reactors must have a turn-turn insulation rating of 2100 Volts
or higher.

IMPORTANT: A 3% reactor reduces motor stress but may cause a degradation of motor waveform quality. Reactors must have a turn-to-turn insulating rating of 2100
volts or higher. Reactors are not recommended for lightly loaded applications because over voltage trips may result at low output frequencies.
Cable is Belden 295xx series or equivalent.

• Figure A.1 shows wiring for single inverter drives (PowerFlex 70 Frames
A-E, PowerFlex 700 Frames 0-6, PowerFlex 700H Frames 9-11 and
PowerFlex 700S Frames 1-11 & 13).
Figure A.2 describes dual inverter drives (PowerFlex 700H/700S Frame
12).
Figure A.3 is for single inverter drives that require parallel reactors
because the drive amp rating exceeds the rating of the largest available
reactor (PowerFlex 700S Frame 13).
• Configurations shown in Figure A.1 and Figure A.3 can be used for
single inverter drives with single or parallel cables, and single-motor or
multi-motor applications.
• The configuration shown in Figure A.2 is used with dual inverter drives
with single or parallel cables, and single-motor or multi-motor
applications.
• Filter (RWR or L-R) must be connected at drive output terminals, less
than 7.6 meters (25 feet) from the drive.
• See the lead length tables for output reactor and resistor selection. The
resistor specification is based on the number of parallel cables used.
• For PowerFlex 700H & 700S Frame 12 drives and some PowerFlex 700S
Frame 13 drives, two reactors are required. In this case, the resistor ohms
and watts ratings are values per phase for each reactor (see lead length
tables for output reactor selection).
• Resistor must be connected to reactor using 150 degree C wire. Select
wire gauge based on rated resistor power from the lead length tables.
• Recommended cables include; XLPE, EPR and Hypalon.
• Maximum total cable distance for resistor wires is 6.1 meters (20 feet) or
3 meters (10 feet) per side.

Glossary
Ambient Air
Air around any equipment cabinet.
See surrounding air for more detail.
Armored
A fixed geometry cable that has a protective “sheath” of continuous metal
Capacitive Coupling
Current or voltage that is induced on one circuit by another because of their
close physical proximity. For drive installations it is generally seen in two
areas:
1. Coupling between motor leads of two drives, such that the operating drive
induces voltage onto the motor leads (and thus the motor) of a
non-operating drive.
2. Coupling between the conductors /or shields of motor leads that creates a
requirement for more current than the motor itself would demand.
CIV (Corona Inception Voltage)
The amplitude of voltage on a motor or other electrical winding that
produces corona (ionization of air to ozone). CIV is increased by adding
phase paper, placing windings in the proper pattern and reducing or
eliminating air bubbles (voids) in the varnish applied.
Common Mode Core
A ferrite bead or core that can be used to pass control, communications or
motor leads through to attenuate high frequency noise. Catalog Number/
Part Number 1321-Mxxx
Common Mode Noise
Electrical noise, typically high frequency, that is imposed on the ground
grid, carriers in an electrical system
Conduit
Conductive ferrous electrical metal tubing used to contain and protect
individual wires
Damp
Wet locations per U.S. NEC or local code
Publication DRIVES-IN001I-EN-P
Glossary-2
Discrete
Individual, hard-wired inputs or outputs, typically used for control of the
drive (Start, Stop, etc.)
Dry
Dry locations per Per NEC Article 100 or local code
dv/dt
The rate of change of voltage over time
Fill Rates
The maximum number of conductors allowed in a conduit, as determined by
local, state or national electrical code.
Fixed Geometry
Cable whose construction fixes the physical position of each conductor
within the overall coating, usually with filler material that prevents
individual conductors from moving.
IGBT
Insulated Gate Bi-Polar Transistor. The typical power semi conductor
device used in most PWM AC drives today
mil
0.001 inches
MOV
Metal Oxide Varistor
NEC
United States National Electric Code NFPA70
Peak Cable Charging Current
The current required to charge capacitance in motor cable. This capacitance
has various components:
– conductor to shield or conduit
– conductor to conductor
– motor stator to motor frame
Publication DRIVES-IN001I-EN-P
Glossary-3
PVC
Polyvinyl Chloride (typically thermoplastic)
RWR
Reflected Waver Reducer, an RL network mounted at or near the drive, used
to reduce the amplitude and rise time of the reflected wave pulses. Cat No
1204-RWR2-09-B or 1204-RWR2-09-C
Shielded
Cable containing a foil or braided metal shield surrounding the conductors.
Usually found in multi-conductor cable. Shield coverage should be at least
75%.
Signal
Individual hard wired analog inputs or outputs, typically used to issue
reference commands or process information to or from the drive.
Surrounding Air Temperature
The temperature of the air around the drive. If the drive is free standing or
wall mounted, the surrounding air temperature is room temperature. If the
drive is mounted inside another cabinet, the surrounding air temperature is
the interior temperature of that cabinet
Terminator
An RC network mounted at or near the motor, used to reduce the amplitude
and rise time of the reflected wave pulses. Catalog Number 1204-TFxx
THHN/THWN
U.S. designations for individual conductor wire, typically 75°C or 90°C
rated and with PVC insulation and nylon coating.
Unshielded
Cable containing no braided or foil sheath surrounding the conductors. Can
be multi-conductor cable or individual conductors.
Wet
Locations with moisture present - see Damp
XLPE
Cross Linked Polyethylene
