Troubleshooting
General Chapter 6 provides information to guide you in troubleshooting. The 1336
FORCE Drive employs extensive diagnostics to aid in correcting many
malfunctions that may occur in the system. This guide is designed to help
you interpret the diagnostic response of the Drive when a malfunction
occurs. Possible corrective measures will be explained to help you get the
Drive repaired or functional as quickly as possible for most types of
malfunctions.
ATTENTION: Only qualified personnel familiar with the
1336 FORCE drive system and the associated machinery should
perform troubleshooting or maintenance functions on the Drive.
Failure to comply may result in personal injury and/or
equipment damage.
!
During Start-up you should have recorded board jumper settings for each
board, board software version numbers, and the drive and motor name
plate data in Table 4.A. If it was not, record it at this time before beginning
any troubleshooting sequences.
Required Equipment For initial troubleshooting, a programming device is required to read fault
codes. In addition to a programming device, the following should be
available 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 1336 FORCE AC 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 improp-
er useage of an oscilliscope and other test equipment. The oscilli-
scope chassis may be at potentially fatal voltage if not properly
grounded. Allen–Bradley does not recommend use of an oscilli-
scope to directly measure high voltages. Use an isolated measur-
ing device with a high voltage probe. Contact Allen–Bradley for
recommendations.
❏ Hand tachometer used to monitor motor velocities.
