Expanded AC Motor Drive Line
In what the company says is the first of
several planned extensions, Rockwell
Automation has expanded the power
range of its Allen-Bradley PowerFlex 755
AC drives to 700 hp (450 kW).
According to Rockwell, the PowerFlex
755 AC drive’s modular design helps
simplify replacement of drive components,
such as cooling fans, circuit
boards and major subassemblies. This
modularity also allows the drive’s converter
and control pod to remain in the
unit while the inverter is rolled out, so
control wiring can remain connected. An
additional advantage is the ability for the
control pod in this drive to be mounted
remotely for hassle-free access to low
voltage control and diagnostics.
Advanced diagnostic capabilities include
indication of blown fuses and blown
surge protectors. Monitoring and tracking
of operating data on cooling fans, I/O
relay cycles and motor run times also provides
valuable data for preventive maintenance,
helping to reduce unplanned
downtime. The PowerFlex 755 drive comes equipped with an embedded
Ethernet port and five option slots that
allow users to tailor the drive to best suit
their application, and now supports
Rockwell Automation Integrated Motion,
allowing it to be configured and controlled
using motion profiles and instruction
sets in an Allen-Bradley ControlLogix
controller with Rockwell Software
RSLogix 5000 software. According to the
company, the ability to support variable
frequency drives, motion drives, I/O,
smart actuators and other Ethernet/IPconnected
devices on a common network
helps increase design flexibility, improve
system performance and reduce engineering
costs.
