MC-700: Allen-Bradley PowerFlex 70/700 Variable Frequency Motor Drives
Course Description
This 32 hour, 4 day hands-on training program is designed to provide
maintenance electricians and engineers with the required knowledge and
skills to install, start‐up and troubleshoot Allen-Bradley PowerFlex 70/700
Variable Frequency AC Drive systems. Emphasis is on using the Human
Interface Module and DriveExplorer software to set and check parameters
used in normal operation and for troubleshooting. Students will locate
power, signal and control terminals, monitor drive conditions, clear faults
and be able to troubleshoot drive and motor problems.
