Q1: What is the primary function of the 20G1F3D960LNDNNNNN?
It is a PowerFlex 755TR regenerative AC drive with TotalFORCE control technology, designed for high-power motor control applications requiring energy regeneration. It converts DC bus energy back into AC power and feeds it into the supply network during braking, significantly reducing energy consumption compared to traditional braking resistor methods .
Q2: What makes the PowerFlex 755TR different from standard PowerFlex 755 drives?
The 755TR features an Active Front End (AFE) synchronous rectifier that enables regenerative capability — energy from overhauling loads or frequent braking cycles is returned to the AC supply instead of being wasted as heat. This eliminates the need for braking resistors and associated cooling equipment, reduces harmonic distortion, and provides significant energy savings in applications such as cranes, hoists, and centrifuges .
Q3: Does this drive require a braking resistor?
No. The regenerative design of the 755TR eliminates the need for braking resistors and braking choppers. Energy is fed back into the supply network, avoiding the heat dissipation and energy waste associated with traditional dynamic braking .
Q4: What communication and control options are available?
The drive features embedded EtherNet/IP for integration with Allen-Bradley ControlLogix and CompactLogix controllers via Studio 5000 Logix Designer . It has five option slots for additional I/O, feedback (encoder, universal feedback), safety (STO, SSM), and communication modules (DeviceNet, ControlNet, PROFIBUS, etc.) .
Q5: Is the 20G1F3D960LNDNNNNN still available?
Yes. The PowerFlex 755T series is listed as Active Mature by Rockwell Automation, meaning it remains in production and fully supported. This specific configuration (Frame 9, 960A, 480V AC, regenerative) is available through authorized distributors, with pricing starting at approximately $103,188 USD for the drive unit . Lead times vary by configuration and distributor.
