Overview Rockwell Automation recognizes that following a defined maintenance
schedule improves drive performance and operational lifespan. By following
this maintenance schedule, you can expect the highest possible uptime.
Annual maintenance 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.
I – Inspection
This indicates that the component should be inspected
for signs of excessive accumulation of dust/dirt/etc. or
external damage (for example, looking at filter
capacitors for bulges in the case, inspecting the
heatsinks for debris clogging the air flow path).
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 or
heating.
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.
