Troubleshooting

Chapter 6 provides a guide to help you troubleshoot the 1397 Drive.
Included is a listing and description of the various Drive faults and
alarms with possible solutions, when applicable.

!

ATTENTION: Only qualified personnel familiar with
the 1397 Drive and associated machinery should
perform troubleshooting or maintenance functions on
the Drive. Failure to comply may result in personal
injury and/or equipment damage.

During Startup you should have recorded board jumper settings for
each board, software version numbers, and the Drive and motor
nameplate data in Tables 4.A, 4.E and 4.G. If they were not, record
them at this time before beginning any troubleshooting procedures.

For initial troubleshooting, a HIM programming device is required to
read fault codes. In addition to a programming device, the following
equipment is recommended before initiating any troubleshooting
procedures:

Digital Multimeter (DMM) capable of 1000V DC/750VAC,
with one megohm minimum input impedance.

Clamp on Ammeter (AC/DC) with current ratings to 2X rated
current output of 1397 DC Drive.

Dual trace oscilliscope with differential capability, digital
storage, two X10 and one X100 calibrated probes (optional but
recommended).

!

ATTENTION: Potentially fatal voltages may result
from improper useage of an oscilliscope and other test
equipment. The oscilliscope chassis may be at
potentially fatal voltage if not properly grounded.
Allen-Bradley does not recommend use of an
oscilliscope to directly measure high voltages. Use an
isolated measuring device with a high voltage probe.
Contact Allen-Bradley for recommendations.

Hand tachometer used to monitor motor velocities.

HIM Programming Device Instruction Manual and reference
manuals for any option used with the 1397 Drive.
