5DX Series 3 Motion Control Assembly
Motor Relay Control
The Motor Relay Control is located on the Motor Relay Control/Stepper Board. It
is utilized by the Motion Enable Control which is discussed in the section entitled
Motion Controller PCI Cards on page 5-38.
On the front edge of the Motor Relay Control/Stepper Board, the Motor Relay
Control supplies signals to several diagnostic LEDs. The LEDs represent the
components monitored by the Motor Relay Control. The LED colors symbolize:
• Red - off under normal conditions and indicating an unexpected state
• Yellow - varies, on or off under normal conditions indicating a controlled event
• Green - on under normal conditions indicating power is supplied
