4 Troubleshooting
Chapter Objectives
The information in this chapter will enable you to:
❏ Maintain the system to ensure smooth, efficient operation
❏ Isolate and resolve system problems
Drive Maintenance
Ensure that the drive's heatplate has proper thermal contact with
the mounting surface. Enclosures must be connected to earth
ground through a grounding electrode conductor to provide a low-
impedance path for ground-fault or noise-induced currents (use a
star washer with the lower mounting screw on the drive). All earth
ground connections must be continuous and permanent. Periodi-
cally check the mounting screws to ensure they are tight.
Motor Maintenance
Inspect the motor regularly to ensure that no bolts or couplings have
become loose during normal operation. This will prevent minor
problems from developing into more serious problems.
Inspect the motor cable periodically for signs of wear. This inspec-
tion interval is duty-cycle, environment, and travel-length dependent.
The cable should not have excessive tensile force applied to it and
should not be bent beyond a one-inch radius of curvature during
normal operation. Tighten all cable connectors.
Reducing Electrical Noise
For detailed information on reducing electrical noise in your system,
refer to the current Compumotor Catalog.
Problem Isolation
When your system does not function properly (or as you expect it to
operate), the first thing that you must do is identify and isolate the
problem. When you accomplish this, you can effectively begin to
resolve and eradicate the problem.
The first step is to isolate each system component and ensure that
each component functions properly when it is run independently.
You may have to dismantle your system and put it back together
piece by piece to detect the problem. If you have additional units
available, you may want to use them to replace existing components
in your system to help identify the source of the problem.
