Chapter 2 Preventative Maintenance and Component Replacement
Regular Maintenance Intervals
The annual maintenance requirements are summarized in the preventative
maintenance schedule on page 19
as a guideline. Detailed procedures referred
to in that table are described the following chapters:
• Chapter 3, Component Inspection and Test Procedures on page 27
• Chapter 4, LV Control Cabinet on page 35
•Chapter 5, Isolation Transformer Cabinet on page 53
• Chapter 6, Power Cell Cabinet on page 59
• Chapter 7, Inspect Connections on page 65
Medium Voltage Motor control equipment should be inspected periodically.
Inspection intervals should be based on environmental and operating
conditions and adjusted as indicated by experience. An initial comprehensive
inspection, within 3 to 4 months after installation, is suggested. See the
following standards for general guidelines for setting-up a periodic
maintenance program.For countries following NEMA standards, refer to
National Electrical Manufacturers Association (NEMA) Standard No. ICS 1.1
(Safety Guidelines for the Application, Installation, and Maintenance of Solid-
Sate Control) for MV Drives and ICS 1.3 (Preventive Maintenance of Industrial
Control and Systems Equipment) for MV Controllers. For countries following
IEC standards, refer to IEC 61800-5-1 Sec. 6.5 for MV Drives and IEC 60470 Sec.
10, IEC 62271-1 Sec. 10.4 for MV Controllers.
The maintenance work for PowerFlex 6000T drives should normally be
performed on a yearly cycle. This work is carried out by Rockwell Automation
medium voltage drive customers. The customer may extend the maintenance
interval appropriately according to the installation conditions and operating
conditions of the drive. Determine the maintenance cycle and component/
items according to the customer site application. The purpose of performing
annual maintenance is to locate potential failures and take preventive
measures before a real failure occurs. Therefore it is recommended to spend
about 16 hours to perform annual maintenance to verify that the drive is
functioning reliably. This can greatly reduce the risk of unplanned downtime.
Before starting preventive maintenance, you should record some important
information, including:
• Report of the previous preventive maintenance (if any)
• Get motor parameters and applications
• Check the current settings of the drive
• Check the fault/warning queue
• Save parameters to a recipe file
(a)
or parameter record
• Record the board part number, serial number, and edition
(b)
(a) For devices with recipe function options.
(b) Records are required only if spare parts replacement is replaced after preventive
maintenance activities.
