Speed control of three phase induction motors using PowerFlex 525 compact AC drive

Abstract

Most of the control systems have to make things move and that generally involves motors. Lifting, blowers, conveyors, pumping, robotics, and fans - pretty much everything uses a motor of some kind. All-purpose single or three-phase motors are huge for simple on/off systems and Inverter-duty motors are particularly designed for operation with variable frequency drives (VFD). They convert electrical energy into mechanical energy, which produces a mechanical rotary action that does some form of work. Alternating current motors are the common types of motors used in commercial and industrial applications. The fundamentals of drive programming and configuration with the PowerFlex 525 compact Alternating current drive, the CompactLogix PLC and the Studio 5000 Logix Designer software is used for configuring these drives. A characteristic that provides complete parameter groups for all the range applications used for the PowerFlex 525 AC Drive. The PowerFlex drive is used with ControlLogix, CompactLogix controllers and different Allen-Bradley products. Point-to-point positioning mode options used for the accurate motor stop at positioning in that system to save money and time during system operation, development, and maintenance. The addition of Allen-Bradley motor control devices into the Logix control devices helps to reduce programming time, ease startup, commissioning and streamline diagnostics.
