Preventive Maintenance Services
Lost productivity caused by poor performance or unplanned failure of your automation assets can significantly reduce your revenue and profitability. A Rockwell Automation Preventive Maintenance Services Agreement allows you to leverage our global network of technical resources to help you design and implement the most efficient preventive maintenance program for optimizing the performance of your assets including drives, programmable logic controllers and motion systems.
What makes our Preventive Maintenance Service Agreement different?
Total protection and peace of mind with the full support of Rockwell Automation to stand behind your preventive maintenance program:- Full-service warranty that ensures we'll repair or replace the parts in the unlikely event of a failure
- 24/7 remote troubleshooting available to get you back on line faster
- Rockwell Automation fully-warranted new or remanufactured replacement parts which ensures compatibility
- Complete documentation of all activities performed during scheduled visits
- Remediation of equipment problems
Preventive Maintenance Activities
Power Off Checks
- Record/Validate Drive, Motor and Feedback Device Nameplate Information
- Verify input voltage
- Remove/open drive covers and inspect for component damage & discoloration
- Examine environment in which drive is installed. (clean, ambient temperature — visual) and record
- Inspect drive power module for arching, contamination and debris; clean and blow-out (air pressured)
- Verify cooling fans are free of contamination and rotate freely
- Examine all AC and DC power terminations; ensure connections are secure per RA Specifications; verify copper
- Examine all I/O wiring terminations; ensure connections are secure per RA Specifications.
- Verify drive wiring remains in compliance with Standard Practices and RA Specifications (wire sizing, ratings, tightness)
- Verify jumpers are properly installed; remove unnecessary jumpers per RA Specifications
- Perform ground checks on drive system (Megger leads in motor only)
- Check drive control power & AC Input protection (Breakers/Fuses) for proper ratings — Verify fuse connections are secure with no discoloration
- Perform power module checks; Resistance checks per Rockwell Automation specification; record measurements
- Review CHANGES TO WIRING — wiring diagram; compare to actual wiring; record differences
Power On — Standby Checks
- Check all status indicators and LEDs on drive for proper state.
- Review fault and alarm queues; record all previous faults and alarms; clear queue when complete.
- Verify any installed HIM displays are functioning/displaying proper information (if applicable)
- Measure and record incoming phase-to-phase AC line voltage
- Measure and record the incoming Phase to Ground AC Line Voltage
- Measure and record the DC Bus voltage
- Measure and record control voltage (If 120VAC, Verify grounded neutral)
- Measure and record power supply levels — Measure and record AC Ripple (PP MV) on DC Power Supplies to insure Power Supply Capacitors have not deteriorated
- Verify cooling fans are operating/blowing air across power module.
- Upload and save drive parameters to a file — Verify backup file revision dates and equate to operating data
- Compare uploaded drive parameters with previously-saved parameter files.
- Scope AC line phase-to-phase.
- Test Customer Software Backup (Customer Permission Required)
Power On — Run Checks
- Measure incoming AC line voltage and current; compare against standby measurement.
- Monitor AC Motor Voltage
- Measure and Record DC Bus Voltage
- Measure and Record Motor Phase Current
- Scope the AC Line Phase to Phase — Waveform
- Scope encoder or tach signal — waveform (if installed)
- Verify operation of the safety and E-stop circuit
Consultation and Remediation
- Review Maintenance & Operator Logs
- Review onsite spare parts availability
- Review installed equipment revisions and compare against any known PSAs
- Perform maintenance & record
