Page 15: Topology
Overview of Drive Topology The PowerFlex 7000 utilizes a Pulse Width Modulated (PWM) – Current Source Inverter (CSI) for the machine side converter as shown in Figure 1.1. This topology offers a simple, reliable, cost-effective power structure that is easy to apply to a wide voltage and power range.
Page 16: Rectifier Designs
Overview of Drive Rectifier Designs Active Front-End (AFE) Rectifier An Active Front-End rectifier is particularly attractive since it does not require an isolation transformer to meet IEEE 519-1992. Many competing technologies in today’s MV market require a multi- winding transformer to mitigate the unwanted harmonics through cancellation by phase shifting the transformer secondary windings.
Page 17: Direct-To-Drive" Technology
“Direct-to-Drive” Technology Reduce the cost, size and weight of your medium voltage drive system with the Allen-Bradley PowerFlex 7000 with Direct-to-Drive technology. This is the first and only technology that allows you to directly connect a medium voltage drive to utility power without the requirement of an isolation transformer.
Page 18: Motor Compatibility
Overview of Drive Motor Compatibility The PowerFlex 7000 achieves near sinusoidal current and voltage waveforms to the motor, resulting in no significant additional heating or insulation stress. Temperature rise in the motor connected to the VFD is typically 3 °C (5.4 °F) higher compared to across-the-line operation.

Catalog Number Explanation – Drive Selection PowerFlex 7000 The PowerFlex 7000 drives have been tested on a dynamometer to Performance verify performance under locked rotor, accelerating, and low speed- high torque conditions. Table B-4 below shows the PowerFlex 7000 (Torque Capabilities) drive torque capabilities as a percent of motor rated torque, independent of the drive’s momentary overload conditions.

Page 199: Appendix D Meggering
Appendix Meggering Drive Meggering When a ground fault occurs, there are three zones in which the problem may appear: input to the drive, the drive, output to the motor. The ground fault condition indicates a phase conductor has found a path to ground. Depending on the resistance of the path to ground, a current with magnitude ranging from leakage to fault level exists.
Page 200: Equipment Required
Meggering There exists the possibility of serious or fatal A T T E N T I O N A T T E N T I O N injury to personnel if safety guidelines are not followed. The following procedure details how the Megger test on the PowerFlex 7000A is to be performed.
Page 201 Meggering Note: It is important to disconnect the terminals on the boards rather than from the ground bus as the grounding cable is only rated for 600 V. Injecting a high voltage on the ground cable will degrade the cable insulation. Do not disconnect the white medium voltage wires from the VSBs.
Page 202 Meggering Potential Transformer Fuses A Megger test may exceed the rating of potential transformer fusing. Removing the primary fuses from all potential and control power transformers in the system will not only protect them from damage but remove a path from the power circuit back to the drive control.
Page 203 Meggering The test should produce a reading greater than the minimum values listed below. If the test results produced a value lower than these values start segmenting the drive system down into smaller components and repeat the test on each segment to identify the source of the ground fault.
Page 204 Meggering 6. Reconnect the Power Circuit to the System Ground Voltage Sensing Boards Securely reconnect the two ground conductors on the VSBs. The two ground connections on the VSB provide a reference point for the VSB and enable the low voltage signal to be fed to the SCBs.

Appendix Preventative Maintenance Schedule Preventive Maintenance The preventive maintenance activities on the PF7000 Air-Cooled Drive Check List (“A” Frame or “B” Frame) can be broken down into two categories: • Operational Maintenance – can be completed while the drive is running.
Page 206: Annual Maintenance
Preventative Maintenance Schedule Annual Maintenance As the name implies, these maintenance tasks should be performed on an annual basis. These are recommended tasks, and depending on the installation conditions and operating conditions, you may find that the interval can be lengthened. For example, we do not expect that torqued power connections will require tightening every year.
