Troubleshooting Guidelines
If your system is not functioning properly, first try these steps.
First Troubleshooting Steps:
•
Are the LEDs illuminated? If not, look for problems with AC and/or +24VDC power.
Also see
System Problems at the end of this chapter.
•
Is the left LED illuminated RED? Try to enable drive by connecting pins 1 and 2 of
the 50 pin DRIVE I/O connector, and issuing a DRIVE1 command.
•
Cycle power to the drive. Cycling power clears most faults.
•
Check wiring and feedback connections
If these steps do not solve your problem, follow the general troubleshooting
procedure outlined below:
General Troubleshooting Procedure
•
Check the LEDs (see the chart below)
•
Launch Motion Planner
•
Verify good RS-232/485 communications
•
Use software commands for problem identification:
TERRLG
reports the last 10 error conditions
TAS
reports on axis status
TASX
extended reports on axis status and conditions
TCS
reports codes for specific faults and warnings
•
Look for non-Drive problems (problems with other parts of the system)
Detailed procedures for each of these topics are given in the rest of this chapter.
LEDs
The drive has two LEDs. The LED on the left can be red or green. The LED on the
right can be yellow or green. LED illumination states, and the conditions they
indicate, are tabulated below.

Establish Communications and Verify Drive Configuration
If you cannot enable the drive, and examining LED conditions has not solved your
problem, then establish communications with the drive and launch Motion
Planner. (See
Chapter 2 Installation
for detailed instructions on establishing
communications. Information about installing and Motion Planner can be found in
the
Gemini GV6K/GT6K Command Reference
.)
If you are unable to establish communications, see
RS-232/485 Communication
Problems
later in this chapter.
