Chapter 4 Commissioning the Drive
Inspect for additional control not shown on the electrical diagram. Determine its
purpose, mark the changes on the electrical diagram, and send the prints to the
factory for future reference.
Perform a tug test on all control cables to ensure that they are securely fastened,
and check each plug and connector to ensure it is properly seated in its socket.
Service Data The Commissioning Guidelines document must include all of the system
nameplate data and variable set points as commissioning proceeds.
Why this Information is Needed
When you commission a PowerFlex 7000 ‘B’ Frame medium voltage AC drive,
the start-up sometimes occurs in an artificial environment. There’s usually no
actual process in operation, and no load, at least not a full load. Therefore, the
application situation is artificial and this isn’t an ideal time to establish parameter
baselines to signature the drive. After commissioning is complete, the drive is at
full capacity and realistic load conditions occur; parameters such as speed
regulation may begin to drift and the drive will not perform as designed to meet
processing requirements.
It is important that you complete the service data in a detailed and accurate
manner, and that immediately after their completion, you submit the data sheets
to both the customer and the factory. This data is necessary for further
modifications on the drive line-up once production commences.
It is common to make modifications to the drive’s program some time during the
two-month period following the drive commissioning. This ensures that speed
control, direction, starting and stopping functions are all performing with
precision.
In addition to system modifications, the factory will use the data sheet as an
indication that the system is running. The date on the commissioning data sheets
indicates to the factory the date that the system started up, and will be used to
commence the product warranty.
In the unlikely event the system is not operating as designed, it will be possible to
trend performance between similar applications and topologies. In the event a
product notification or recall is required, the factory uses the datasheets to
identify if the customer falls under the definition for an update.
ATTENTION: Ensure that there is sufficient clearance between the installed
control wiring to the control cabinet and components carrying medium voltage.
Verify that closing the low voltage door does not swing the low voltage cables
into the medium voltage cabling section.
