Who Should Use This 

Manual

This manual is intended for use by personnel familiar with medium voltage 

and solid-state variable speed drive equipment. The manual contains material 

that enables regular operation and maintenance of the drive system.

What Is Not in This Manual This manual provides information specific to maintaining the PowerFlex 7000 

‘B’ frame drive. This document does not include topics such as:

• Physically transporting or siting the drive cabinetry

• Installing or commissioning procedures

• Spare parts lists compiled for your order. 

Rockwell Automation provides the site- and installation-specific electrical and 

design information for each drive during the order process cycle. If they are 

not available on site with the drive, contact Rockwell Automation.

If you have multiple drive types or power ranges, ensure you have the correct 

documentation for each specific PowerFlex 7000 product:

• ‘A’ frame for lower-power air-cooled, configurations (up to 

approximately 1250 hp/933 kW)

• ‘B’ frame for higher-power, air-cooled configurations (standard or 

heatpipe models)

• ‘C’ frame for all liquid-cooled configurations

PowerFlex 7000 Drive Overview

The PowerFlex™ 7000 drive is a general-purpose, standalone, medium voltage 

drive that controls speed, torque, direction, starting, and stopping of standard 

asynchronous or synchronous AC motors. This drive works on numerous 

standard and specialty applications such as fans, pumps, compressors, mixers, 

conveyors, kilns, fan-pumps, and test stands in industries such as 

petrochemical, cement, mining and metals, forest products, power generation, 

and water/waste water. 

The PowerFlex 7000 drive meets most common standards from these 

organizations: 

• National Electrical Code (NEC)

• International Electrotechnical Commission (IEC)

• National Electrical Manufacturers Association (NEMA)

• Underwriters Laboratories (UL)

• Canadian Standards Association (CSA). 

The drive is available with the world’s most common supply voltages at 

medium voltage, from 2400…6600V. The design focuses on high reliability, 

ease of use, and lower total cost of ownership.

Topology The PowerFlex 7000 drive uses a pulse width modulated (PWM) – current 

source inverter (CSI) topology. This topology applies to a wide voltage and 

power range. The power semiconductor switches used are easy-to-series for 

any medium voltage level. Semiconductor fuses are not required for the power 

structure due to the current limiting DC link inductor.

With 6500V PIV rated power semiconductor devices, the number of inverter 

components is minimal. For example, only six inverter switching devices are 

required at 2400V, 12 at 3300…4160V, and 18 at 6600V. 

The PowerFlex 7000 drive also provides inherent regenerative braking for
