The Blue servo light indicates that the servos have been turned on. If this won’t illuminate that means that the E-Stop string is open or there is a problem with the drives or the control. If you hear the servos engage (1CR is energized) when the button is pressed, but the blue light is off, replace the bulb (#53 miniature bayonet).

• Check the that the E-stops on CNC and Operator's station Both need to be released.

• Check that the Operator's station is plugged into the CNC control

• Check the 1CR relay on the connect card in the control, be sure it is plugged in.

• Check voltage from chassis to CRDY test-point on Connect Card.

  • At "Please turn servos on" prompt, CRDY should stay near zero volts when Servos On button is pressed.

  • If voltage at CRDY goes up to 12V

    • the ribbon cable to motion card could be bad

    • or the problem could be on motion card (5AX card).

  • If CRDY stays low

    •  the E-Stop string could be open

    • or ribbon cable to front panel connect card could be bad

    • or Servos On push button could be bad.
