PowerFlex 700 Adjustable Frequency AC Drive – Frames 0…6
Step 1: Read the Precautions and General Information
Qualified Personnel
ATTENTION:
Only qualified personnel familiar with adjustable frequency AC drives and associated machinery must 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
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 following points (refer to pages 28 through
30 for locations):
•
+DC and -DC terminals of the Power Terminal Block
•
+DC terminal of the Power Terminal Block and the chassis
•
-DC terminal of the Power Terminal Block and the chassis
The voltage must be zero for all three measurements.
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 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 hardwired stop circuit can be required to remove the AC line to the drive. An auxiliary braking method can be required.
ATTENTION:
Loss of control in suspended load applications can cause personal injury and/or equipment damage. Loads must always be controlled by the drive or a mechanical brake. Parameters 600…611 are designed for lifting/torque proving applications. It is the responsibility of the engineer and/or end user to configure drive parameters, test any lifting functionality and meet safety requirements in accordance with all applicable codes and standards.

Product Safety
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 can result in malfunction of the system.
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 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.
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 bus voltage is increasing toward a level that causes 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
“OverSpeed Limit” fault (F25) occurs if the speed reaches [Maximum Speed] +
[Overspeed Limit], (parameters 82 and 83). If this condition is unacceptable, action must 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).
•
Actual deceleration times can be longer than commanded deceleration times.
However, a “Decel Inhibit” fault (F24) 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 provides equal or better performance in most cases.
Important: These faults are not instantaneous. Test results have shown that they can take between 2…12 seconds to occur.

EMC Instructions
CE Conformity
Conformity with the Low Voltage (LV) Directive and Electromagnetic
Compatibility (EMC) Directive has been demonstrated by using harmonized
European Norm (EN) standards published in the Official Journal of the
European Communities. PowerFlex Drives
(1)
comply with the EN standards listed below when installed according to the information supplied in this publication and the Wiring & Grounding Guidelines Manual.
CE Declarations of Conformity are available online at: http://www.rockwellautomation.com/rockwellautomation/certification.
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
•
Some drives are equipped with an adhesive label on the top of the drive. 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 must be kept as short as possible to avoid electromagnetic emission as well as capacitive currents.
•
Use of line filters in ungrounded systems is not recommended.
•
PowerFlex drives can cause radio frequency interference if used in a residential or domestic environment. The installer 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.
•
When operated on a public supply system, it is the responsibility of the installer or user to ensure, by consultation with the distribution network operator and Rockwell Automation, if necessary, that applicable requirements have been met.
(1) 600V class drives below 77A (Frames 0…4) are declared to meet the essential requirements of the Low Voltage Directive. It is the responsibility of the user to determine compliance to the EMC directive.
