Our 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.
What's New?
Expand predictive maintenance to your plant
By combining FactoryTalk® Analytics™ GuardianAI™ with PowerFlex 755 VFDs, you can get an unprecedented view into the health of your plant assets.
This solution continuously monitors variable frequency drives and plant assets and alerts you to problems before they occur, giving you more time to plan and act. With actionable insights, you can reduce risk, optimize maintenance plans and keep applications running more reliably.
Monitor VFD health
- Calculate the expected life of critical drive components based on actual use and environment
- Project the remaining life span of fans, transformers, air filters and more
- See component runtime hours for power cells, fans and temperatures out of normal operating range
Monitor plant assets
- Analyze live electrical signal data from your existing PowerFlex VFDs, at high speeds right at the edge without the overhead of cloud infrastructure
- Predict and identify failures of your pump, fan or blower
- Get notifications of flow restrictions, cavitation, loose mounting, blade misalignments, bearing faults, and so on

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 lets operators perform some process or maintenance work without stopping the machine.
- The integrated safety functions option module provides advanced safety on an EtherNet/IP network. Safety instructions are based on IEC 61800-5-2 and include the ability to monitor speed, direction and position. When it is used as part of an integrated safety system that includes a GuardLogix® 5580ES controller or Compact GuardLogix 5380ES controller, the integrated safety functions option module provides safety ratings up to and including SIL CL3 and PLe Cat 4. Studio 5000 Logix Designer® application version 31 or later is also required.
Applications
The PowerFlex® 755 AC drives meet the needs of a wide range of applications, including:
- Material handling
- Metals
- Mining
- Oil and gas
- Refining
- Tire and rubber
PowerFlex 755 On-Machine Drive
If you’re looking for a variable-frequency drive that combines the performance of the well-established PowerFlex 755 VFD with the benefits of an on-machine solution, you just found the perfect answer.
Our PowerFlex® 755 On-Machine™ Drive is a simple, cost-effective pre-engineered product that can be mounted right on or near your machine. The drive has an IP66 environmental rating and incorporates I/O, network communications and safety options into a single package that connects easily to your application.
On-machine advantages
Placing your AC drive on or near your machine provides benefits that can save you both time and money. It can also reduce floor space and help to cut downtime. Here’s how:
- The IP66 enclosure rating allows the drive to be mounted near the machine or motor to reduce the length of cables and installation costs
- Panels can be smaller, resulting in more available floor space for production
- Plug ‘n play connections reduce installation and commissioning time
- Using a pre-engineered solution saves design time and helps with faster installation with fewer mistakes
