Troubleshooting Your 8720MC Servo Drive
Chapter Objectives This chapter provides information to help you determine the cause of
a drive fault or improper 8720MC Drive operation and define possible
corrective actions. This chapter includes:
• Required Equipment
• Start-up Troubleshooting Procedures
• Viewing the Fault Queue
• Fault Descriptions
• Understanding the Fault Parameters
• Troubleshooting the Digital I/O
• Troubleshooting SCANport I/O
• Troubleshooting the 8720MC-RPS Regenerative Power Supply
• Supplemental Troubleshooting Information
Required Equipment The 8720MC can be equipped with a resident HIM display module. If
not, it will be necessary to use a remote HIM module or DriveExplorer
to troubleshoot the drive. The A-B remote HIM (catalog number
1203-HA2, Series B or later) or (20-HIM-Ax) can be connected to the
external SCANport connector. As an alternative to the HIM, a
computer running Windows
®
or a handheld running Windows CE
®
can be used as a diagnostic tool. The available computer should be
equipped with the A-B DriveExplorer
software. Use of DriveExplorer
also requires the 1203-SSS Serial to SCANport adapter. For operating
instructions refer to the DriveExplorer Getting Results Manual
(publication 9306-GR001x-EN-E). In addition to these diagnostic tools
a volt meter, a battery box, and some small hand tools may be
necessary. In rare instances an oscilloscope may be necessary to
analyze feedback signals.
