Troubleshooting
Chapter Objectives Chapter 4 provides information specific to troubleshooting the
Master/Slave version of the 1336 FORCE drive. Much of the
troubleshooting information that pertains to standalone 1336 FORCE
drives can be applied to the Master/Slave drive. Refer to the 1336
FORCE user manual (1336 FORCE-5.12) for tests and diagnostic
routines that can be applied to the Master/Slave. The focus of this
chapter is on components and tests that are specific to the FORCE
Master/Slave units.
Required Equipment For initial troubleshooting, a programming device (or DriveTools) 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
◗ Clamp on Ammeter (AC/DC) with current ratings to 2x rated
output current of the 1336 FORCE Master/Slave drive.
◗ Dual trace oscilliscope with differential capability, digital storage,
two X10 and one X100 calibrated probes (optional but
recommended).
!
ATTENTION: Only qualified personnel familiar with
the 1336 FORCE Master/Slave 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.

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.
