Chapter 3 Component Definition and Maintenance
• If there have been any changes to the system during the outage, place the
drive in System Test Operating Mode and verify all functional changes.
Final Power Checks (pre-Restart)
• Ensure all cabinets are cleared of tools, and all component connections are
back in place and in the running state.
• Put all equipment in the normal operating mode, and apply medium
voltage.
• If there were any input or output cables removed, verify the input phasing,
and bump the motor for rotation.
• If there were any changes to the motor, input transformer, or associated
cabling, you will have to retune the drive to the new configuration using
Autotuning.
• Save all parameter changes (if any) to NVRAM.
• Run the application up to full speed/full load, or to customer satisfaction.
• Capture the drive variables while running, in the highest access level if
possible.
Additional Preventive Maintenance Tasks
• Investigation of customer’s concerns relating to drive performance
– Relate any problems found during above procedures to customer issues.
• Informal instruction on drive operation and maintenance for plant
maintenance personnel
– Reminder of safety practices and interlocks on MV equipment, and on
specific operating concerns
– Reminder of the need to properly identify operating conditions
• Recommendation for critical spare parts which should be stocked in-plant
to reduce production downtime
– Gather information on all spare parts on site, and compare that with
factory-recommended critical spares to evaluate whether levels are
sufficient.
– Contact MV Spare Parts group for more information.
• Vacuum Bottle Integrity Testing using a Vacuum Checker or AC Hipot
– Refer to Publications 1502-UM050_EN-P (Series D) and 1502-
UM052_-EN-P (Series E) for a detailed description of all 400A
contactor maintenance.
Final Reporting
• A complete, detailed report on all steps in the Preventive Maintenance
procedures should be recorded to identify changes.
– A completed copy of this checklist should be included.
