Offering power ratings from 0.37 to 30kW at 400 to 480V, PowerFlex 700 ac drives are easily configurable for both volts-per-Hertz and sensorless vector applications -- all in a flexible and compact form factor around half that of similarly rated alternative drives.
The new drive's side-by-side 'zero stacking' design -- combined with directed airflow, dual articulating cover hinges, and book shelf form factor -- reduces its space requirement to around half that of similarly rated competitive brand drives.
Installation and maintenance of the PowerFlex 700 is simple and straightforward, thanks to features such as a removable cable entry plate, and an easy-to-remove cassette housing the main control and I/O board. The cassette is common to all drive ratings, further simplifying training and installation.
Like its compatriot -- the PowerFlex 70 -- the Power Flex 700 meets world power ratings, packaging requirements and electromagnetic compatibility (EMC) standards. Drive compliance includes C-Tick, CE-Mark, CSA/cUL certification and UL listing.
For reduced startup time and operator training, PowerFlex 700 drives use a seven-line, graphical LCD human-interface module (HIM). The LCD HIM supports multi-lingual text for grouping, parameter descriptions, programming, troubleshooting and startup.
The PowerFlex 700 features 'S.M.A.R.T. Start' -- a set of the most commonly programmed parameters, including start/stop, minimum and maximum speed, acceleration and deceleration time, reference source and thermal motor overload.
These parameters allow the user to achieve fast and easy start-up without having an in-depth knowledge of the parameter structure.
For more sophisticated set-ups, complete, prompted startup routines are also available. In addition, the PowerFlex 700 offers a configurable autotune routine, which precisely measures motor parameters to improve torque performance in demanding applications.
The PowerFlex 700's internal communication options support the drive's integration into Rockwell Automation NetLinx open network architecture, as well as other global standard communication networks.
The list of network adaptors includes: DeviceNet, ControlNet, Universal Remote I/O, Profibus and Interbus-S.
The Allen-Bradley PowerFlex family -- PowerFlex 70 (0.37 to15kW), PowerFlex 700, and PowerFlex 7000 medium voltage (373 to 3,700kW) ac drives -- all share a similar programming structure. This ensures ease of use and reduces setup time.
