Periodic and Preventive Maintenance
Schedule Codes Explanations
The following codes are used to indicate the tasks that are associated with the
components that are identified in the recommended tasks and maintenance
schedule tables on pages
.
ATTENTION:
Servicing energized industrial control equipment can be
hazardous. Severe injury or death can result from electrical shock, burn, or
unintended actuation of controlled equipment.
Recommended practice is to disconnect and lock out / tag out control
equipment from power sources, and discharge stored energy in the system, if
present. If it is necessary to work in the vicinity of energized equipment, only
qualified personnel are permitted to perform such work. Adhere to all
applicable safety practices and wear protective equipment.
IMPORTANT
Review product manuals for detailed maintenance information relevant for
a particular model.
Code
Task
Description
I
Inspect
Inspect the component for signs of excessive accumulation of dust, dirt, or
external damage. For example, inspect the drive heatsink fan inlet screen for
debris that can block the airflow path.
C
Clean
Clean the components, specifically the drive heatsink fan inlet screen.
M
Maintain
This type of maintenance task can include tightening loose terminal and cable
connectors.
R
Replace
This component has reached its mean operational life. Replace the component to
decrease the chance of failure. It is likely that components can exceed the
designed life in the drive, but component life is dependent on many factors such
as usage, and heat.
RFB/R
Refurbish/Replace
The parts can be refurbished, at lower cost, or replaced with new ones.

Review
A discussion with Rockwell Automation® personnel is recommended to help
determine whether any of the enhancements/changes made to the drive
hardware and control could benefit the application.
