VFD Basics Using PowerFlex 525 Drives

Course Overview

This hands-on course provides comprehensive training on Allen-Bradley PowerFlex 525 Variable Frequency Drives (VFDs). Students learn to configure, program, and troubleshoot VFDs for industrial motor control applications, from basic setup through Ethernet integration with PLCs.

Topics Covered

• Variable Frequency Drive fundamentals and theory

• Three-phase AC motor basics

• Power wiring: input (single-phase with derating) and output (3-phase)

• Drive startup procedures and LED status indicators

• HIM (Human Interface Module) operation

• Basic drive parameter setup using the HIM

• Drive control methods: 2-wire and 3-wire start/stop configurations

• Internal versus external control wiring

• 4-20 mA analog speed reference control

• Advanced drive features and parameters

• Ethernet interface module installation

• Drive configuration using Connected Components Workbench

Hands-On Lab Exercises

• Wire power input and motor output connections

• Perform initial drive startup and configuration

• Configure 2-wire and 3-wire start/stop control

• Set up analog speed reference using 4-20 mA signals

• Install and configure Ethernet interface module

• Control the drive from a PLC over Ethernet/IP

• Diagnose and troubleshoot common VFD faults

Who Should Attend

This course is designed for maintenance technicians, controls engineers, and electricians. No prior VFD experience is required.
