PowerFlex 755T Drives Overview
PowerFlex 755T drive products provide harmonic mitigation, regeneration, non-regenerative, and common bus solutions that help reduce energy costs, gain flexibility, and increase productivity. PowerFlex drives use TotalFORCE technology to achieve motor control through precise, adaptive control of torque, velocity, and position. TotalFORCE technology incorporates several patented features that are designed to help optimize your system and maintain productivity through improved machine uptime.
PowerFlex 755TL and 755TR drives expand the proven PowerFlex family product portfolio and provide solutions for harmonic mitigation and regeneration. These drives offer energy saving features and simplified installation and startup. PowerFlex 755TL and 755TR products include enhanced corrosive gas protection (XT) to help provide electrical reliability and suitability in industrial environments with corrosive atmospheres.
PowerFlex 755TS drives incorporate TotalFORCE technology into a traditional six-pulse drive. These drives can be used in a wide range of applications from fans, pumps, and conveyors to more advanced motor control processes that require high performance features typically found in specialized drive solutions. PowerFlex 755TS drives also offer real-time operational intelligence, automated commissioning, and optimization.

Safe Stop Functional Safety
The Integrated Safety Functions option module provides a networked STO (Safe Torque Off) function via an EtherNet/IP™ network. It is also equipped for Integrated (drive-based) Timed SS1, Monitored SS1, and Safe Brake Control, which operate in the drive and are activated through the network safety connection.
The Integrated Safety Functions option module also supports select controller-based EN/IEC 61800-5-2 safety functions operating in safety controllers that use the EtherNet/IP network to communicate with the safety I/O. This support includes the safety function instructions that are provided on the Drive Safety tab in the Logix Designer application.
This chapter provides detailed instructions for starting up a regenerative drive, regenerative bus supply, and common bus inverter after you have completed repairs and before power has been applied.
