For this module: For this LED:
Status of the
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
