Preventative Maintenance Schedule
PowerFlex 6000
Maintenance Schedule This Annual Preventative Maintenance Program includes a visual inspection of
all drive components visible from the front of the unit, 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.
M – Maintenance
This indicates a maintenance task that is outside the normal preventative
maintenance tasks.
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.
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.
