Troubleshooting Basics
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 have accomplished this, you
can effectively begin to resolve 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 exchange them with existing components in your system to help identify the
source of the problem.
Determine if the problem is mechanical, electrical, or software-related. Can you repeat or re-
create the problem? Random events may appear to be related, but they are not necessarily
contributing factors to your problem. You may be experiencing more than one problem. You
must isolate and solve one problem at a time.
Log (document) all testing and problem isolation procedures. You may need to review and
consult these notes later. This will also prevent you from duplicating your testing efforts.
Once you isolate the problem, refer to the problem solutions contained in this chapter. If the
problem persists, contact your local technical support resource (see Technical Support below).
Reducing Electrical Noise
Refer to the guidelines on page 21. General information on reducing electrical noise can be
found in the Engineering Reference section of the Parker Compumotor/Digiplan catalog.
Appendix B (page 47) provides guidelines on how to install the OEM6250 in a manner most
likely to minimize the OEM6250’s emissions and to maximize the OEM6250’s immunity to
externally generated electromagnetic interference.
Diagnostic LEDs
STATUS ............. Green if +5VDC (4A min.) power is connected. Red if power reset is required.
Off if no power.
DISABLED .......... Off = O.K. On (red) if drive is disabled; potential causes:
• Drive is not connected.
• No AC power to the drive.
• Shutdown (
SHTNC or SHTNO ) input is active; potential causes:
- DRIVE¯, DRIVEx¯, or DRIVE¯¯ command was executed.
- Drive Fault (
DFT ) input is active, or an erroneous drive fault error was
detected because the drive fault level (DRFLVL setting) is incorrect.
- Enable ( ENBL ) input is not grounded.
- Max. allowable position error (SMPER value) exceeded.
- A Kill command (K, !K or K) was issued, or a Kill input
or user fault input was activated while the Disable Drive on Kill
feature was enabled (refer to the KDRIVE command).
Test Options
• Test Panel. Motion Architect’s Panel Module allows you to set up displays for testing
system I/O and operating parameters.
• Hardware Test Procedure (see pages 22-23).
