The system module and each axis module has one LED visible from the front of the module. The LEDs are labeled "Status" on all axis modules and "Status" for GMC, Analog Servo, and 9/440 versions and "I/O Ring Status" for the CNC Interface system. They indicate status as follows:
For this module: For this LED: Status of the
LED: Potential Cause: Possible resolution:
GMC Turbo, GMC or Analog Servo System Module
Status Steady red Malfunctioning system module. • Verify wiring.
• Secure wiring connections. • Replace the module.
• Contact your local Allen-Bradley Support Representative.
Flashing red A fault has occurred in system. • Verify wiring.
• Secure wiring connections. Alternating
red and green
DC bus is not up. • Apply three-phase power. • Check DC bus LED. Open fuse or malfunctioning
contactor on user-supplied 3 phase input.
• Check wiring to start/stop circuitry. • Check fuse.
Malfunctioning system module. Replace the module. Steady green The bus is up and axes are enabled. None needed. Flashing
green
The bus is up, but no axis is enabled (Analog Servo only).
• Check axes and enable them, if necessary. • Verify that enable wiring is correct and not
open. Enable signal from position
controller is not present (Analog Servo only).
• Check axes and enable them, if necessary. • Verify that enable wiring is correct and not
open.
• Check connections on input wiring board. Position controller has detected a
machine system malfunction and will not enable the 1394 (Analog Servo only).
• Check position controller. • Check the machine.
• Check the enable status at the Analog Servo wiring board.
System enable is not powered (GMC only).
• Check the enable status.
• Check for 24V DC on system enable signal, TB1 and TB2 (refer to the chapter Wiring
1394 GMC and GMC Turbo Systems, Figure
4.1 and Figure 4.2). Not
illuminated
There is no power to the system module.
For this module: For this LED: Status of the
LED: Potential Cause: Possible resolution:
CNC Interface System Module
I/O Ring Status
Steady red The fiber optic ring has failed at some point before the 1394 system module.
Check all components and connections before the 1394 on the fiber optic ring.
Flashing red The fiber optic ring has failed at some point after the 1394 system module.
Check all components and connections after the 1394 on the fiber optic ring.
Not illuminated
No power to the system.
This LED is not illuminated when operating normally.
Check 24V control power and 460V AC input power for the 1394.
9/440 System Module
XILINX Steady red Operating normally. None needed. Not
illuminated
Power to the system module is not on.
• Cycle power.
• Apply power to the system module. An XILINX hardware fault has
occurred.
• Replace the system module.
• Contact your local Allen-Bradley Support Representative.
WATCHDOG Steady red Operating normally. None needed. Not
illuminated
Power to the system module is not on.
Apply power to the system module. Watchdog has timed out and a
processor failure has occurred.
• Cycle power.
• Replace the system module.
• Contact your local Allen-Bradley Support Representative.
Status Steady red Operating normally. None needed. Not
illuminated
Power to the system module is not on.
Apply power to the system module. Watchdog has timed out and a
processor failure has occurred.
• Cycle power.
• Replace the system module.
• Contact your local Allen-Bradley Support Representative.
R-I/O Steady or flashing red
For systems with remote I/O, this indicates that communication with remote I/O is occurring.
None needed.
Not illuminated
Your system does not have remote I/O or you have not enabled remote I/O in your program.
• Verify that you have purchased the remote I/O option for this system.
• Verify that you have enabled the remote I/O in your PAL program.

LED: Potential Cause: Possible resolution:
Axis Module Status Steady red Malfunctioning axis module. • Verify wiring.
• Verify that the slider and terminator are securely engaged.
• Secure wiring connections. • Replace the module. Flashing red Axis fault has occurred. • Verify wiring.
• Secure wiring connections.
• Check fault status on the HIM (Analog Servo only), in GML (GMC only), or on the operator panel (CNC Interface and 9/440). • Check 460V AC input power.
• Check axis status on the HIM (Analog Servo only), in GML (GMC only), and on the operator panel (CNC Interface and 9/440)
Alternating red and green
DC bus is not up. • Check the system module’s LED.
• Check slider connections to verify that they are properly seated.
• Verify that the terminator is present on the last axis.
Flashing green
Axis is not enabled. • Check axes and enable them, if necessary. • Verify that enable wiring is correct and not
open. Enable signal from position
controller is not present (Analog Servo only).
• Check axes and enable them, if necessary. • Verify that enable wiring is correct and not
open. Incorrect wiring or loose
connections.
Check connections on the input wiring board. Axis setups may not be correct for
the application.
• Verify that axis definitions are correct. • Check tuning parameters.
Not illuminated
There is no power to the axis module.
Verify that the terminator is present on the last axis.
There is no power to the system. • Verify that the terminator is present on the last axis.
