When reading this document, look for this symbol “ Step x ” to guide
you through the 5 BASIC STEPS needed to install, start-up and
program the PowerFlex 70. The information provided Does Not
replace the User Manual and is intended for qualified drive service
personnel only. For detailed PowerFlex 70 information including
application considerations and related precautions refer to the following:

Read the General Precautions
ATTENTION: 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 may result if ESD control procedures are not
followed. If you are not familiar with static control procedures,
reference A-B publication 8000-4.5.2, “Guarding Against Electrostatic
Damage” or any other applicable ESD protection handbook.
ATTENTION: 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 may result in malfunction of
the system.
ATTENTION: Only qualified personnel familiar with adjustable
frequency AC drives and associated machinery should plan or
implement the installation, start-up and subsequent maintenance of the
system. Failure to comply may result in personal injury and/or
equipment damage.
ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has discharged before performing 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 the User
Manual for location). The voltage must be zero.

PowerFlex 70 Adjustable Frequency AC Drive Quick Start
ATTENTION: Configuring an analog input for 0-20mA operation and
driving it from a voltage source could cause component damage. Verify
proper configuration prior to applying input signals.
!
ATTENTION: Hazard of personal injury or equipment damage exists
when using 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.
!
ATTENTION: 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.
!
ATTENTION: The “adjust freq” portion of the bus regulator function
is extremely useful for preventing nuisance overvoltage faults resulting
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 would
otherwise cause a fault; however, it can also cause either of the
following two conditions to occur.
1. Fast positive changes in input voltage (more than a 10% increase
within 6 minutes) can cause uncommanded positive speed changes;
however an “OverSpeed Limit” fault will occur if the speed reaches
[Max Speed] + [Overspeed Limit]. If this condition is unacceptable,
action should be taken to 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” portion of the bus regulator function
must be disabled (see parameters 161 and 162).
2. 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 and 162). In addition, installing a properly sized
dynamic brake resistor will provide equal or better performance in most
cases.
Note: These faults are not instantaneous and have shown test results
that take between 2 and 12 seconds to occur.

EMC Instructions
CE Conformity
Conformity with the Low Voltage (LV) Directive and Electromagnetic
Compatibility (EMC) Directive has been demonstrated using
harmonized European Norm (EN) standards published in the Official
Journal of the European Communities. PowerFlex Drives comply with
the EN standards listed below when installed according to the User and
Reference Manuals.
CE Declarations of Conformity are available online at:
http://www.ab.com/certification/ce/docs.
Low Voltage Directive (73/23/EEC)
•
EN50178 Electronic equipment for use in power installations.
EMC Directive (89/336/EEC)
•
EN61800-3 Adjustable speed electrical power drive systems Part 3:
EMC product standard including specific test methods.
General Notes
•
If the adhesive label is removed from the top of the drive, 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.
•
The motor cable should be kept as short as possible in order to avoid
electromagnetic emission as well as capacitive currents.
•
Use of line filters in ungrounded systems is not recommended.
•
PowerFlex drives may cause radio frequency interference if used in a
residential or domestic environment. The user is required to take
measures to prevent interference, in addition to the essential
requirements for CE compliance listed below, if necessary.
•
Conformity of the drive with CE EMC requirements does not
guarantee 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 Reference Manual.

Essential Requirements for CE Compliance
Conditions 1-6 listed below must be satisfied for PowerFlex drives to
meet the requirements of EN61800-3.
1. Standard PowerFlex CE compatible Drive.
2. Review all important precautions/attention statements throughout
this manual prior to drive installation.
3. Grounding as described on page 1-4 of the User Manual.
4. Output power, control (I/O) and signal wiring must be braided,
shielded cable with a coverage of 75% or better, metal conduit or
equivalent attenuation.
5. All shielded cables should terminate with the proper shielded
connector.
6. Conditions in Table A.

If the wires are short and contained within a cabinet which has no sensitive circuits, the use of
shielded wire may not be necessary, but is always recommended.

Start-Up Check List
❏ 1. Verify input supply voltage.
❏ 2. Check output wiring.
❏ 3. Check control wiring.
❏ 4. Apply AC power and control voltages to the drive.
If any of the six digital inputs are configured to Stop – CF
(CF = Clear Fault) or Enable, verify that signals are present or the
drive will not start. Refer to Troubleshooting – Abbreviated Fault &
Alarm Listing on page 16 for a list of potential digital input conflicts.
If the STS LED is not flashing green at this point, refer to Status

Type 2 Alarms
Some digital input programming may
cause conflicts that will result in a Type
2 alarm. Example: [Digital In1 Sel] set
to 5 “Start” in 3-wire control and
[Digital In2 Sel] set to 7 “Run” in2-wire.
Refer to Troubleshooting –
Abbreviated Fault & Alarm Listing on
page 16 for information on resolving
this type of conflict.
(5) Auto/Manual - Refer to Figure 1.6 in
the User Manual for details.
(6) Opening an “Enable” input will cause
the motor to coast-to-stop, ignoring
any programmed Stop modes.
(7) A “Dig In ConflictB” alarm will occur if a
“Start” input is programmed without a
“Stop” input.

Manually Clearing Faults
Step
1. Press Esc to acknowledge the fault. The fault information will be
removed so that you can use the HIM.
2. Address the condition that caused the fault.
The cause must be corrected before the fault can be cleared.
3. After corrective action has been taken, clear the fault by one of
these methods:
• Press Stop
• Cycle drive power
• Set parameter 240 [Fault Clear] to “1.”
