Step 1: Read the Precautions and General Information
Qualified Personnel
ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and associated machinery can plan or implement the installation, startup,
and subsequent maintenance of the system. Failure to comply can result in personal injury and/or equipment damage.
Personal Safety
ATT EN TIO N: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before per forming any work on the drive. Measure
the DC bus voltage at the +DC terminal of the Power Terminal Block and the -DC test point (refer to Frame A, B, C, D Power Terminal Block, and DC Bus Test
Point s on page 19 for location). The voltage must be zero.
ATT EN TIO N: Risk of injury or equipment damage exists. DPI™ or SCANport™ host products must not be directly connected together via 1202 cables.
Unpredictable behavior can result if two or more devices are connected in this manner.
ATT EN TIO N: The drive start/stop/enable control circuitry includes solid-state components. If hazards due to accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exist, an additional hard-wired stop circuit may be required to remove the AC line to the drive. An auxiliary braking
method may be required.
PowerFlex 70 Adjustable Frequency AC Drive
Product Safety
ATT EN TIO N: An incorrectly applied or installed drive can result in component damage or a reduction in product life. Wiring or application errors, such as,
undersizing the motor, incorrect or inadequate AC supply, or excessive ambient temperatures can result in malfunction of the system.
ATT EN TIO N: This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing,
servicing, or repairing this assembly. Component damage can result if ESD control procedures are not followed. If you are not familiar with static control
procedures, reference Guarding Against Electrostatic Damage, publication 8000-4.5.2 or any other applicable ESD protection handbook.
ATT EN TIO N: Configuring an analog input for 0…20 mA operation and driving it from a voltage source could cause component damage. Verify proper
configuration before applying input signals.
ATT EN TIO N: A contactor or other device that routinely disconnects and reapplies the AC line to the drive to start and stop the motor can cause drive hardware
damage. The drive is designed to use control input signals that start and stop the motor. If an input device is used, operation must not exceed 1 cycle per minute
or drive damage can occur.
ATT EN TIO N: The “adjust freq” por tion of the bus regulator function is useful for preventing nuisance overvoltage faults that result from aggressive
decelerations, overhauling loads, and eccentric loads. It forces the output frequency to be greater than commanded frequency while the drive’s bus voltage is
increasing towards levels that can cause a fault; however, it can also cause either of the following two conditions to occur.
• Fast positive changes in input voltage (more than a 10% increase within 6 minutes) can cause uncommanded positive speed changes; however an F25
“OverSpeed Limit” fault occurs if the speed reaches P82 [Max Speed] + P83 [Overspeed Limit]. If this condition is unacceptable, take theses actions;
1) limit supply voltages within the specification of the drive and,
2) limit fast positive input voltage changes to less than 10%. Without taking such actions, if this operation is unacceptable, the “adjust freq” por tion of the
bus regulator function must be disabled (see parameters 161 [Bus Reg Mode A] and 162 [Bus Reg Mode B]).
• Actual deceleration times can be longer than commanded deceleration times; however, a “Decel Inhibit” fault is generated if the drive stops decelerating
altogether. If this condition is unacceptable, the “adjust freq” portion of the bus regulator must be disabled (see parameters 161 [Bus Reg Mode A] and 162
[Bus Reg Mode B]). In addition, installing a properly sized dynamic brake resistor provides equal or better performance in most cases.
Note: These faults are not instantaneous and have shown test results that take 2...12 seconds to occur.
Rockwell Automation Publication 20A-IN009F-EN-P - April 20185
PowerFlex 70 Adjustable Frequency AC Drive
Output Contactor Precaution
ATT EN TI ON : To guard against drive damage when using output contactors, the following information must be read and understood. One or more output
contactors can be installed between the drive and motors for disconnecting or isolating certain motors/loads. If a contactor is opened while the drive is
operating, power is removed from the respective motor, but the drive continues to produce voltage at the output terminals. In addition, reconnecting a motor
to an active drive (by closing the contactor) could produce excessive current that can cause the drive to fault. If any of these conditions are determined to be
undesirable or unsafe, wire an auxiliary contact on the output contactor to a drive digital input that is programmed as “Enable.” With the drive Enable input
that is wired to the output contactor, the drive can coast-to-stop (cease output) whenever the output contactor is opened.
EMC Instructions
The following section provides instructions for Electromagnetic Compatibility (EMC) compliance.
CE Conformity
Conformity with the Low Voltage (LV) and EMC Directive has been demonstrated by using harmonized European Norm (EN) standards that are
published in the Official Journal of the European Communities. PowerFlex Drives comply with the EN standards that are listed when installed
according to the user manuals and reference manuals.
CE declarations of conformity are available online at:
• EN61800-5-1, electronic equipment for use in power installations.
EMC Directive (2014/30/EU)
• EN61800-3, adjustable speed electrical power drive systems Part 3: EMC product standard including specific test methods.
General Notes
• Some drives are equipped with an adhesive label on the top of the drive. If the adhesive label is removed, the drive must be installed in an
enclosure with side openings less than 12.5 mm (0.5 in.) and top openings less than 1.0 mm (0.04 in.) to maintain compliance with the LV
directive.
• Use a motor cable that is as short as possible to avoid electromagnetic emission and capacitive currents.
• Do not use line filters in ungrounded systems.
• PowerFlex drives can cause radio interference if used in a residential or domestic environment. Follow national and local industrial safety
regulations and/or electrical codes, in addition to the essential requirements for CE compliance (see page 7
• Conformity of the drive with CE EMC requirements does not mean that an entire machine or installation complies with CE EMC
requirements. Many factors can influence total machine/installation compliance.
• PowerFlex drives can generate conducted low-frequency disturbances (harmonic emissions) on the AC supply system. More information
regarding harmonic emissions can be found in the PowerFlex 70 EC and 700 VC Reference Manual, publication PFLEX-RM004.
), to prevent radio interference.

AC Supply Source Considerations
PowerFlex 70 drives are suitable for use on a circuit capable of delivering up to a maximum of 200,000 rms symmetrical amperes, and a maximum of
600V.
ATTENTION: To guard against personal injury and/or equipment damage that is caused by improper fusing or circuit breaker selection, use the recommended
line fuses/circuit breakers that are specified in Drive, Fuse, and Circuit Breaker Ratings on page 22
.
If the drive has a system ground fault monitor (residual current-operated protective device), use Type B (adjustable) devices to avoid nuisance
tripping.
Unbalanced, Ungrounded, High Resistance or B-phase Grounded Distribution Systems
Install an isolation transformer on an ungrounded distribution system where the line-to-ground voltages on any phase could exceed 125% of the
nominal line-to-line voltage. See Wiring and Grounding Guidelines for PWM AC Drives, publication DRIVES-IN001
, for more information on
impedance grounded and ungrounded systems.
Input Power Conditioning
Some events on the power system supplying a drive can cause component damage or shortened product life. These events are divided into two basic
categories that are described:
• All Drives
– The power system has power factor correction capacitors that are switched in and out of the system, either by the user or by the power
company.
– The power source has intermittent voltage spikes in excess of 6000V. These spikes could be caused by other equipment on the line, or by
events such as lightning strikes.
– The power source has frequent interruptions.
• 5 Hp or Less Drives (in addition to all drives above)
– The nearest supply transformer is larger than 100 kVA, or the available short circuit (fault) current is greater than 100,000 A.
– The impedance in front of the drive is less than 0.5%.
If any or all of these conditions exist, we recommend that you install a minimum amount of impedance between the drive and the source. This
impedance could come from the supply transformer itself, the cable between the transformer and drive, or an additional transformer or reactor. To
calculate the impedance, use the information that is supplied in the Wiring and Grounding Guidelines for Pulse Width Modulated (PWM) AC
Drives, publication DRIVES-IN001
.

Single-phase Input Power
The PowerFlex 70 drive is typically used with a three-phase input supply. Underwriters Laboratories (UL) lists the drive to operate on single-phase
input power. Single-phase operation provides 50% of the three-phase rated current. See 208/240 Volt AC Single-phase Input Drive Ratings and
Input Protection Devices on page 24 through 600 Volt AC Single-phase Input Drive Ratings and Input Protection Devices on page 26.

General Grounding Requirements
IMPORTANT The safety ground for the drive (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. Check the integrity
of all ground connections periodically.
For installations within a cabinet, one safety ground point or ground bus bar connected directly to building steel (girder, joist) can be used. All
circuits including the AC input ground conductor can be grounded independently and directly to this point/bar.

Typical Grounding
Safety Ground (PE)
The safety ground for the drive is required by code. This point must be connected to adjacent building steel (girder, joist), a floor ground rod, or bus
bar (see Typical Grounding). Grounding points must comply with national and local industrial safety regulations and/or electrical codes.
Shield Termination - SHLD
The shield terminal (see Typical Power Terminal Block Location (B frame shown) on page 17) provides a grounding point for the motor cable
shield. The motor cable shield can be connected to this terminal on the drive (on the drive end) and the motor frame (on the motor end). A shield
terminating cable gland can also be used.
If you use shielded cable for control and signal wiring, the shield can be grounded at the source end, and not the drive end.
RFI Filter Grounding
IMPORTANT Use RFI filters only in inst allations with grounded AC supply systems that are permanently installed and solidly grounded (bonded) to
the building power distribution ground.
If you use an optional radio frequency interference (RFI) filter, relatively high ground leakage currents can be present. Be sure that the incoming
supply neutral is solidly connected (bonded) to the same building power distribution ground. Grounding must not rely on flexible cables and must
exclude any form of plug or socket that permits inadvertent disconnection. Some local codes require redundant ground connections. Periodically
check the integrity of all connections. See the instructions that are supplied with the filter
ATT EN TI ON : The PowerFlex 70 does not provide branch short circuit protection. See Drive, Fuse, and Circuit Breaker Ratings on page 22
for the recommended fuse or circuit breaker to protect against short circuits.
.
Power Wiring
ATTENTION: National Codes and standards (NEC, VDE, BSI, and others) and local codes outline provisions for safely installing electrical
equipment. Installation must comply with specifications regarding wire types, conductor sizes, branch circuit protection, and disconnect
devices. Failure to do so can result in personal injury and/or equipment damage.
Cable Types Acceptable for 200…600V Installations
Various cable types are acceptable for drive installations. For many installations, unshielded cable is adequate as long as the cable is separated from
sensitive circuits. As an approximate guide, provide a spacing of 0.3 m (1 ft) for every 10 m (32.8 ft) of length. In all cases, do not use long parallel
runs. Do not use cable with an insulation thickness fewer than 15 mils (0.4 mm/0.015 in.). Use copper wire. Wire gauge requirements and
recommendations are based on 75 °C (167 °F). Do not reduce wire gauge when using higher temperature wire.
20Rockwell Automation Publication 20A-IN009F-EN-P - April 2018
PowerFlex 70 Adjustable Frequency AC Drive
Unshielded
Thermoplastic High Heat-resistant Nylon-coated (THHN), Thermoplastic Heat and Water-resistant Nylon-coated (THWN), or similar wire is
acceptable for drive installation in dry environments as long as adequate free air space and/or conduit fill rate limits are provided. The wire must
have a minimum insulation thickness of 15 mils (0.4 mm/0.015 in.) and cannot have large variations in insulation concentricity.
IMPORTANT Do not use THHN or similarly coated wire in wet areas.
Shielded/Armored Cable
Shielded cable contains the general benefits of multi-conductor cable with the added benefit of a copper braided shield that can contain much of the
noise that is generated by a typical AC Drive. Use shielded cable for installations with sensitive equipment such as weigh scales, capacitive proximity
switches, and other devices that can 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 can also help reduce shaft voltage and induced bearing currents for some applications. In addition, the increased impedance of
shielded cable can help extend the distance that the motor can be from the drive without the addition of motor protective devices, such as
terminator networks. See Reflected Wave in Wiring and Grounding Guidelines for PWM AC Drives, publication DRIVES-IN001
Consider the general specifications of the environment of the installation, including temperature, flexibility, moisture characteristics, and chemical
resistance. In addition, a braided shield can be included and be specified by the cable manufacturer as having coverage of at least 75%. An additional
foil shield can greatly improve noise containment.
A good example of recommended cable is Belden 295xx (xx determines gauge). This cable has four Cross-linked Polyethylene (XLPE) insulated
conductors with a 100% coverage foil and an 85% coverage copper braided shield (with drain wire) surrounded by a Polyvinyl Chloride (PVC)
jacket.
Other types of shielded cable are available, but the use of these types can limit the allowable cable length. For example, some of the newer cables
bundle four conductors of THHN wire and wrap them tightly with a foil shield. This type of construction can greatly increase the cable charging
current that is 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 is not known.

ATTENTION: To avoid a possible shock hazard that is caused by induced voltages, unused wires in the conduit must be grounded at both
ends. Also, if a drive sharing a conduit is being serviced or installed, disable all drives that are using that conduit. Disabling all drives helps
minimize the possible shock hazard from cross coupled motor leads.
Motor Cable Lengths
Typically, motor lead lengths less than 30 m (approximately 100 ft) are acceptable. However, if your application requires longer lengths, refer to
Wiring and Grounding Guidelines for Pulse Width Modulated (PWM) AC Drives, publication DRIVES-IN001, for details.

Drive, Fuse, and Circuit Breaker Ratings
Integral solid-state short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance
with the National Electric Code (NEC) and any additional local codes, or the equivalent. The tables on the following pages provide drive ratings
(including continuous, 1 minute and 3 seconds) and recommended AC line input fuse and circuit breaker information. Both types of short circuit
protection are acceptable for UL and IEC requirements. Sizes that are listed are the recommended sizes that are based on 40 °C (104 °F) and the
U.S. N.E.C. Other country, state, or local codes may require different ratings.
Fusing
The recommend fuse types are listed. If available current ratings do not match those listed in the tables that are provided, choose the next higher
fuse rating.
• IEC – BS88 (British Standard) Parts 1 & 2, EN60269-1, Parts 1 & 2
• UL – UL Class CC, T, RK1, or J should be used.
Circuit Breakers
The “non-fuse” listings in the following tables include inverse time circuit breakers, instantaneous trip circuit breakers (motor circuit protectors),
and 140M self-protected combination motor controllers. If one of these devices is chosen as the desired protection method, the following
requirements apply:
• IEC – Both types of circuit breakers and 140M self-protected combination motor controllers are acceptable for IEC installations.
• UL – Only inverse time circuit breakers and the specified 140M self-protected combination motor controllers are acceptable for
UL installations.

Jumper Installation, Removal, and Storage
PowerFlex 70 drives use plug-in style jumpers. Most drives have a jumper storage area inside the front cover. Store any extra jumpers, or jumpers that
have been removed, in this storage area.
In some cases, a protective cover is installed over the jumper pins that extend from the board. If there is a protective cover, remove the cover, install
(or remove) the jumper, and replace the cover.

Step 4: I/O Wiring
Important points to remember about I/O wiring:
• Use copper wire. Wire gauge requirements and recommendations are based on 75 °C (167 °F). Do not reduce wire gauge when you are using
higher temperature wire.
• Wire with an insulation rating of 600V or greater.
• Control and signal wires must be separated from power wires by at least 0.3 m (1 ft).
IMPORTANT I/O terminals that are labeled “(–)” Digital In Common or “Common” are not connected to earth ground and are designed to greatly reduce common mode
interference. Grounding these terminals can cause signal noise.
ATT EN TI ON : Hazard of personal injury or equipment damage exists when usin g bipolar input sources. Noise and drift in sensitive input circuits can cause
unpredictable changes in motor speed and direction. Use speed command parameters to help reduce input source sensitivity.

By default, you can program a digital input as an enable input. The status of this input is interpreted by drive
software. If the application requires the drive to be disabled without software interpretation, a hardware
enable configuration is used. To use the hardware enable configuration, remove the enable jumper (ENBL
JMP) and connect the enable input to Digital In 6 (see below).
1. Remove the drive cover.
2. Locate and remove the enable jumper on the main control board (see the diagram).
3. Connect the enable to Digital In 6 (see I/O Terminal Designations – Enhanced Control

Safe Torque Off Board Option
The optional PowerFlex Safe Torque Off board, when used with suitable safety components, provides
protection according to EN ISO 13849-1 and EN 62061 for Safe Torque Off and protection against restart.
The PowerFlex safe torque off option is just one safety control system. All components in the system must be
chosen and applied correctly, to achieve the desired level of operator safeguarding.
IMPORTANT The drive enable digital input is a solid-state circu it. The safety outputs on the safety module must not be
configured for pulsed/safety pulse test.
PowerFlex 70 Adjustable Frequency AC Drive
IMPORTANT The drive ships with the hardware enable jumper (ENBL JMP) installed. You must remove the jumper if you
are using the DriveGuard Safe Torque Off option. If you do not remove the jumper, the drive faults when a
start command is issued.

The PowerFlex 70 is designed so that startup is simple and efficient. If you have an LCD HIM, two start-up methods are provided. Select the desired
start-up routine that is needed for the application:
• S.M.A.R .T. Start
This routine lets you quickly configure the drive by programming values for the most commonly used functions (see Running S.M.A.R.T. Start on
).
page 43
• Assisted Startup
This routine prompts you for information to start up a drive for most applications, such as line and motor data, commonly adjusted parameters, and
I/O. With enhanced control, two levels of assisted startup are available: basic and detailed (see Running an Assisted Startup on page 43
IMPORTANT Power must be applied to the drive when viewing or changing parameters. Previous
programming can affect the drive status when power is applied.
