Allen-Bradley PowerFlex 755 AC Drives Products Drives & Motors Low Voltage AC Drives Architecture Low-Voltage AC Drives

PowerFlex® 755 AC Drives provide ease of use, application flexibility, and high performance. They include multiple control and hardware options, as well as optional embedded safety features. These drives are well-suited for a wide variety of motor control applications including pumps, fans, and conveyors. With Integrated Motion on EtherNet/IP™, you can place these drives on the same network as Kinetix® drives. A Dual-port EtherNet/IP™ Option Module supports ring, linear, and star topologies, as well as Device Level Ring (DLR) functionality for fault tolerant connectivity and high drive availability.

Pre-engineered Power Option Bay provides cost-effective solution for popular power options

Dual-port EtherNet/IP Option Module helps you leverage EtherNet/IP networks, minimize the number of managed switches, and reduce cabling needs when using Device Level Ring (DLR) networks

Automatic Device Configuration (ADC) allows Logix controllers to detect a replaced drive and download all configuration parameters automatically

V/Hz control, vector control with FORCE™ technology, sensorless vector control, and permanent magnet motor control

Integrated Motion on EtherNet/IP eases drive configuration and control by using profiles and instruction sets embedded in the Studio 5000 Logix Designer® application

Predictive diagnostics for increasing the life of cooling fans and relay outputs

Configuration and programming via integral LCD Human Interface Module (HIM), DriveTools SP software, or Connected Components Workbench software

Supports easy integration through the embedded EtherNet/IP port and five option slots that support feedback, I/O, safety, and communications modules and an auxiliary 24V DC power supply

Available Safety Options

Safe Torque Off option is available as a networked or hardwired solution, both certified at SIL 3, PLe, Cat 3. This option removes rotational power to the motor without removing power from the drive for faster start-up after a demand on the safety system.

Safe Speed Monitor option is certified at SIL 3, PLe, Cat 4 option allows you to safely monitor and control the speed of your application. This allows operators to perform some process or maintenance work without stopping the machine.
