Preventative Maintenance Schedule

7000A-UM151D-EN-P – March 2013

7000 “A” Frame



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. For more details, please refer to Chapter 5
(Component Definition and Maintenance) of this User Manual.

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.
