The Allen Bradley PowerFlex 755T Series is a high-performance line of variable frequency drives (VFDs) engineered for advanced motor control, regenerative energy systems, and harmonic mitigation in industrial environments. These drives are built for large-scale operations requiring precision, reliability, and energy efficiency—offering features like active front-end (AFE) technology, common DC bus capability, and embedded Safe Torque Off (STO). PowerFlex 755T drives are widely used in water treatment plants, heavy manufacturing, cranes, mills, and high-inertia systems that demand continuous uptime and sophisticated motor coordination.

The PowerFlex 755T is used in high-demand applications that require precise speed and torque control, energy regeneration, and improved power quality. It’s commonly deployed in coordinated drive systems, multi-motor control panels, and energy-intensive operations where performance and efficiency are essential.
PowerFlex 755T drives are available in 400V, 480V, and 690V classes, supporting motor outputs from 10 HP to well over 3000 HP depending on configuration. These drives come in both air- and liquid-cooled versions for flexible integration in a variety of industrial settings.
Each PowerFlex 755T part number provides detailed information about voltage, current, enclosure, and options. For example:
20G14ND156JA0NNNNN │ │ │ │ └─ Options and firmware │ │ │ └─ Enclosure/configuration │ │ └─ Output current or HP (156 = 156A) │ └─ Voltage class (D = 480V) └─ Family code (20G14 = PowerFlex 755T)
PowerFlex 755T drives include active front-end (AFE) capability, regenerative braking, and built-in harmonic mitigation. They also support Safe Torque Off (STO), Safe Speed Monitor (SSM), and seamless Logix integration for advanced control and diagnostics. These features make the 755T ideal for energy-critical and safety-rated environments.
Yes. PowerFlex 755T drives are designed to integrate directly with Studio 5000 Logix Designer via Add-On Profiles (AOPs). This allows for centralized configuration, drive diagnostics, safety setup, and real-time feedback through a Logix-based PLC system.
