PowerFlex 70 Adjustable Frequency AC Drive

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

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 Frame A, B, C, D Power Terminal Block, and DC Bus Test Points on page 19 for location). The voltage must be zero.

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 hard-wired stop circuit may be required to remove the AC line to the drive. An auxiliary braking method may be required.

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: 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.

ATTENTION: 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.

ATTENTION: The “adjust freq”portion 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”portion 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 2018

PowerFlex 70 Adjustable Frequency AC Drive

Output Contactor Precaution

ATTENTION: 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(1)

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:

http://www.rockwellautomation.com/rockwellautomation/certification/overview.page

Low Voltage Directive (2014/35/EU)

• 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), to prevent radio interference.

•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.

(1) CE certification testing has not been completed for 600V class drives.

Step 3: Wire the Drive – Wire Recommendations

This section describes wiring recommendations for the drive.

Opening the Cover

To open the cover, follow the steps for your drive enclosure that is shown.

IP20 NEMA/UL Type 1

1. Loosen the cover screw.

2. Pull the cover straight off the chassis to avoid damaging the connector pins.

IP66 NEMA/UL Type 4X/12 (for Indoor Use Only)

1. Loosen the cover screws.

2. Pull the cover straight off the chassis.

IMPORTANT Torque cover screws to 0.79 N•m (7 lb•in).

IP66 NEMA/UL Type 4X/12 Indoor Installations

Use the plugs that are supplied with IP66 NEMA/UL Type 4X/12 rated drives to seal unused holes in the conduit entry plate.

For the best seal, be sure that the inner rim of the plug is fully seated against the edge of the conduit entry hole.
