Chapter 5 Commissioning the Drive
If the dimensional and electrical prints are not available, request copies from the
factory. In addition, if the drawings require changes to accurately suit the
installation and application of the system, please fax or e-mail them to the factory
for revision.
Electrical System One-line Diagram
After reviewing the Rockwell Automation electrical and dimensional drawings,
obtain a copy of the electrical system one-line drawing to help identify all relevant
equipment tag identification names and numbers. Study the system for power
sources and parallel paths of medium voltage power to the drive. Retain a copy of
the one-line diagram for the drive commissioning and, if possible, send a copy to
the Medium Voltage division for archiving and use in the event of future
customer assistance requests.
Verify One-line Diagram on Site
After reviewing all documentation, perform an on site inspection of the drive.
While referencing the one-line diagram and Rockwell Automation prints,
identify all the locations of the components within the drive line-up by their tag
identification name or number. Trace the power cables from point to point while
following the electrical diagrams. Note and review any discrepancy between the
physical installation and the electrical prints prior to commissioning the drive.
Inspection Process
Before commissioning the drive line-up, you must inspect the process to which
the drive is applied. This step is not only important as a means of identifying and
understanding how the equipment design adapts to the customer’s application,
but also to identify any potential hazards. Review the process and identify any
necessary measures to ensure that commissioning the equipment will not expose
anyone to hazardous situations, or in any way do damage to the equipment
involved in the application.
ATTENTION: Verify that the load is not turning due to the process. A
freewheeling motor can generate voltage that will be back-fed to the
equipment being serviced. Take all action necessary to ensure that motor
regeneration into the drive does not occur while the equipment is being
serviced.
