Maintenance Schedule, Cont’d
Rockwell recognizes that following a defined maintenance schedule will deliver the maximum product availability. By rigorously following this maintenance schedule, the Customer can expect the highest possible
uptime. This Annual Preventative Maintenance Program includes a visual inspection of all drive components visible from the front of the unit, resistance checks on the power components, power supply voltage level
checks, general cleaning and maintenance, checking of all accessible power connections for tightness, and other tasks.
Schedule Codes
I – Inspection
This indicates that the component should be inspected for signs of excessive accumulation of dust/dirt/etc. or external damage (e.g. looking at Filter Capacitors for bulges in the case, inspecting the heatsinks for
debris clogging the air flow path, etc.).
M – Maintenance
This indicates a maintenance task that is outside the normal preventative maintenance tasks, and can include the inductance testing of Line Reactors/DC Links, or the full testing of an isolation transformer.
R – Replacement
This indicates that the component has reached its mean operational life, and should be replaced to decrease the chance of component failure. It is very likely that components will exceed the design life in the drive,
and that is dependent on many factors such as usage, heating, etc.
C – Cleaning
This indicates the cleaning of a part that can be reused, and refers specifically to the door-mounted air filters in the liquid-cooled drives and some air-cooled drives.
Rv – Review
This refers to a discussion with Rockwell Automation to determine whether any of the enhancements/changes made to the Drive Hardware and Control would be valuable to the application.
RFB/R – Refurbishment/Replacement
The parts can be refurbished at lower cost OR the parts can be replaced with new ones.
MAINTENANCE OF INDUSTRIAL CONTROL EQUIPMENT
ATTENTION: Servicing energized Industrial Control Equipment can be hazardous. Severe injury or death can result from electrical shock, bump, or unintended actuation of controlled equipment. Recommended
practice is to disconnect and lockout control equipment from power sources, and release stored energy, if present. Refer to National Fire Protection Association Standard No. NFPA70E, Part II and (as applicable)
OSHA rules for Control of Hazardous Energy Sources (Lockout/Tagout) and OSHA Electrical Safety Related Work Practices for safety related work practices, including procedural requirements for lockout-tagout, and
appropriate work practices, personnel qualifications and training requirements where it is not feasible to de-energize and lockout or tagout eectric circuits and equipment before working on or near exposed circuit
parts.
