The PowerFlex 755 series, represented by model 20G1AND415AA0NNNNN, is engineered to deliver superior performance, energy savings, and robust control for demanding industrial applications. Our global logistics network ensures timely delivery to your facility, whether in North America, Europe, or Asia.
The Allen-Bradley PowerFlex 755 is a premium AC drive designed for complex applications requiring high performance and flexibility. This specific model offers dual horsepower ratings: 350 HP for Normal Duty (ND) and 300 HP for Heavy Duty (HD) cycles, providing application versatility. It features advanced control capabilities to optimize motor performance and system efficiency.
Key Features and Technical Advantages:
Dual Horsepower Design: Offers operational flexibility with 350HP (ND) and 300HP (HD) ratings, allowing you to select the optimal power profile for your specific load and duty cycle requirements.
Advanced Control Architecture: Utilizes Allen-Bradley's patented sensorless vector control technology, providing high starting torque, precise speed regulation, and improved process control without the need for a feedback device.
Integrated Safety: Supports embedded safety functions (when configured with appropriate options), helping machines meet safety standards by providing Safe Torque Off (STO) and other safety-rated stops.
Common Components and Design: Shares a common form factor and user interface with other PowerFlex 755 drives, simplifying spare parts inventory, technician training, and maintenance procedures across your facility.
Energy Optimization: Includes intelligent energy-saving algorithms that automatically adjust voltage and current to match motor load, significantly reducing power consumption during light-load conditions.
Durability and Reliability: Built with high-quality components and designed for harsh industrial environments, featuring a robust NEMA Type 1 (Open) enclosure suitable for panel mounting in controlled environments.
Technical Specifications Table:
| Parameter | Specification |
| Input Voltage | 380-480V AC, 3 Phase, 50/60 Hz |

Frequently Asked Questions (FAQ):
Q1: What is the difference between the Normal Duty (350HP) and Heavy Duty (300HP) ratings on this drive?
A: The Normal Duty rating is for applications with standard load cycles and lower overload requirements. The Heavy Duty rating is for applications with high starting torque, constant high load, or frequent overloads (like crushers or conveyors with heavy material). The drive can deliver higher current for short periods in HD mode, but the continuous power is rated at 300HP.
Q2: Is a feedback device (encoder) required for sensorless vector control?
A: No, that is the advantage of "sensorless" vector control. The drive algorithm estimates motor speed and torque based on electrical motor models and input power, eliminating the cost and maintenance of a physical encoder in many applications.
Q3: What communication protocols are supported natively?
A: This drive features built-in dual-port EtherNet/IP. Additional communication protocols like DeviceNet, ControlNet, or Profibus are available through optional plug-in communication adapter modules, providing flexibility for various network environments.
Q4: Can this drive be used for both constant torque and variable torque applications?
A: Yes, the PowerFlex 755 is versatile. Its control modes are suitable for constant torque applications like conveyors and mixers, as well as variable torque applications like pumps and fans, where significant energy savings can be achieved.
Q5: What is included with the drive unit?
A: The drive is supplied as a chassis unit. It typically includes a removable Human Interface Module (HIM) for local control and programming. External braking resistors, line filters, or communication cards are optional and can be sourced separately based on your application needs.
Q6: How do I program and configure this drive?
A: Configuration can be done directly using the built-in HIM keypad. For more advanced setup and monitoring, Rockwell Automation's free Connected Components Workbench (CCW) software can be used over the Ethernet connection.
Q7: What are the typical lead times for this product?
A: As a trading company with established supply channels, we generally maintain stock or can source this model efficiently. Specific lead times depend on current availability and can be confirmed upon inquiry.
Q8: Do you provide technical support for installation and commissioning?
A: We provide basic technical documentation and product support. For complex system integration and on-site commissioning, we recommend working with a certified system integrator or your local Allen-Bradley technical support channel.
