3.21.2 23-1* Maintenance
Wear and tear calls for periodic inspection and service of
elements in the application, e.g. motor bearings, feedback
sensors and seals or filters. With Preventive Maintenance
the service intervals may be programmed into the
frequency converter. The frequency converter will give a
message when maintenance is required. 20 Preventive
Maintenance Events can be programmed into the
frequency converter. For each Event the following must be
specified:
•
Maintenance item (e.g. "Motor Bearings")
•
Maintenance action (e.g. "Replace")
•
Maintenance Time Base (e.g. "Running Hours" or
a specific date and time)
•
Maintenance Time Interval or the date and time
of next maintenance
NOTE
To disable a Preventive Maintenance Event the associated
23-12 Maintenance Time Base must be set to Disabled [0].
Preventive Maintenance can be programmed from the LCP,
but use of the PC-based VLT Motion Control Tool MCT10 is
recommended.
