Gemini GT6 Hardware Installation Guide
If your system is not functioning properly, first try these steps.
First Troubleshooting Steps:
• Is the left LED illuminated? If not, look for problems with AC 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 or Pocket Motion Planner
• Verify good RS-232/485 communications
• Save the configuration file
• 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.
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.
Left LED Right LED
(Green/Red) (Yellow/Green)
off Yellow
Red (flashing) off
Red (flashing) Yellow (flashing)
Red Green
Green Green (flashing)
Green Yellow/Green (flashing) Autorun mode
Red off
Green off
If you cannot enable the drive, and examining LED conditions have not solved
your problem, then establish communications with the drive and launch Motion
Planner or Pocket Motion Planner. (See Chapter 2 Installation for detailed
instructions on establishing communications. Information about installing and
using these software programs can be found in the Gemini Programmer's Refer-
ence.)
If you are unable to establish communications, see RS-232/485 Communication
Problems later in this chapter.
