The new Allen-Bradley PowerFlex 755 AC drive from Rockwell Automation has a range of features, allowing more options for motor control and integration flexibility. With safety features, DeviceLogix embedded control technology, embedded Ethernet connectivity and predictive diagnostics, the PowerFlex 755 AC drive is a functional and a cost-effective motor control solution.
Representing the first drive from the new Allen-Bradley PowerFlex 750 series, the PowerFlex 755 AC drive is available in power ranges from 7.5 to 250kW at 400/480V AC and 540/650V DC inputs. It supports multiple languages, meets global standards or certifications and is suitable for industries, including manufacturing, food and beverage, water/wastewater, materials handling, metals, mining and automotive.
According to Rockwell Automation, a variety of supporting options makes the PowerFlex 755 a functional and a cost-effective drive for simple and demanding drive applications. The application flexibility and integration make the PowerFlex 755 drive suitable for OEMs and system integrators looking to reduce engineering costs, deliver machines to market faster and meet end-user demand for higher performance and safer machines.
The embedded Allen-Bradley DeviceLogix control technology in the PowerFlex 755 drive optimises its productivity and simplifies programming. Users have control flexibility to combine inputs and/or outputs and local logic functions to determine the PowerFlex 755 drive’s behaviour. The PowerFlex 755 drive can process up to 90 function blocks with integrated instruction types to help configuration.
The PowerFlex 755 drive has two safety options. Safe torque-off prevents drive restarts following the tripping of safety circuits. Safe-speed monitoring combines the safe-torque-off functionality with Rockwell Automation safe-speed control core technology in one hardware option. Safe-speed control reduces and monitors the speed of an application to allow an operator to inspect and perform some process maintenance work without stopping the machine completely, thereby maximising productivity.
To enable data-driven decisions, embedded Ethernet in the PowerFlex 755 drive allows users to easily configure, control and collect drive data over EtherNet/IP networks. The drive’s predictive diagnostics capability minimises downtime by monitoring drive status such as cooling fans, I/O relay cycles, motor run-time hours or fault warnings and allows preventative action to be taken.
The PowerFlex 755 AC drive’s design incorporates a slot-based mechanical architecture that allows customers to tailor the drive with options such as I/O, feedback, safety, communications and auxiliary control power as per the requirements of their applications.
