Chapter 4 Commissioning
If the dimensional and electrical prints are not available, a copy can be sent 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
so they may be revised.
Electrical System One-line Diagram
Once the Rockwell Automation electrical and dimensional drawings are clearly
understood, a copy of the electrical system one-line drawing should be obtained.
In studying this drawing, all relevant equipment tag Identification names and
number should be identified. The system should be studied for sources of power
and parallel paths of medium voltage power to the drive. A copy of the one-line
diagram should be retained for the drive commissioning and if possible sent to
the Medium Voltage division where it will be archived and used in the event that
future customer assistance is required.
Verify One-line Diagram on Site
Once all documentation has been reviewed, an on site inspection of the drive
line-up is required. 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. Any discrepancy between
the physical installation and the electrical prints should be reviewed prior to
commencing the drive commissioning.
Inspect Process
Before commencing commissioning on the drive line-up it is important to inspect
the process which the drive has been applied to. This step is not only important as
a means of identifying and understanding how the equipment is designed to
adapt to the customer’s application, but it will also be used to identify any
potential hazards. Review the process and determine what measures need to be
taken 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.
