PowerFlex 70 Adjustable
Frequency AC Drive
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:
Title Publication
PowerFlex 70 User Manual 20A-UM001x
PowerFlex Reference Manual PFLEX-RM001x
Available… on the CD supplied with the drive or at www.ab.com/manuals/dr
Step 1 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.

!
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 .

Control and signal wires should be separated from power wires by at least 0.3 meters (1 foot).
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.
I/O terminals labeled “(–)” or “Common” are not referenced to earth ground and are designed to greatly reduce common mode interference. Grounding these terminals can cause signal noise.

A start command is required following initiation of this setting. The parameter returns to “Ready” (0) following the test, at which time another start transition is required to operate the drive in normal mode. Important: Used when motor is uncoupled from the load. Results may not be valid if a load is coupled to the motor during this procedure.

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.

this type of conflict.

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.”
