Introduction Chapter 1
• PLC Program: The PLC I/O processes control signals within the drive
and I/O signals to and from the customer’s control system and input
circuit breaker. The PLC program is standardized. However, it may be
customized to address specific customer requirements by Rockwell
Automation during the Application Engineering phase of order execution.
Pre-commissioning Customer Meeting
Before commissioning the drive, it is recommended to schedule a meeting with
the customer.
1. Discuss the activities and documentation needed to review the drive
application
2. Review the start-up activities and timelines
3. Review the Pre-commissioning Checklist (see 6000-IN006_-EN-P)
4. Review the drive application
Review Drive Application
To ensure trouble-free commissioning, it is necessary for all personnel involved in
the start-up to familiarize themselves with the drive and actual application.
Service on the equipment should not be performed without a clear
understanding of how the equipment has been designed to function and how the
equipment has been applied.
Before commissioning the drive, inspect the process that the drive is intended to
control. This identifies how the equipment is designed to suit the application,
and any potential hazards. Determine what measures must be taken to ensure that
commissioning the equipment does not expose anyone to hazardous situations or
damage to the equipment. Verify that the load is not turning due to the process,
as a freewheeling motor can generate voltage that will be back-fed to the
equipment being serviced. Take all actions necessary to ensure that motor
regeneration into the drive does not occur while the equipment is being started
up or being serviced.
Review Electrical System One-line Diagram
Identify all relevant equipment Tag Identification names and numbers. Study the
system for sources of power and parallel paths of medium voltage power. Retain a
copy of the one-line diagram for commissioning the drive. If applicable, send a
copy of the one-line diagram to the Start-up Project Manager to be archived and
used for future customer assistance.
