Probability How-To Steps Need More?
High
1. Power off the machine (see "Power Off the Machine" (page35)).
2. Examine the connectors at the J6 connection at the machine control board,
and the ribbon cables at the axes drivers:
a. Remove the connectors, and inspect them for any bent pins or
discoloration.
b. Firmly reseat the connectors.
Examine the ribbon cable 423 from the
control board (J6) to the axes motors.
Cause: The DC-BUS board is malfunctioning.
Probability How-To Steps Need More?
Medium The loss of DC-BUS board power to one or more axes is likely if the axes driver
LEDs are not on, if they're dim, or if they're a color other than green.
Examine the axis status LEDs on the axis drivers.
For information, see "There's a blown
fuse on the DC-BUSboard" in "One
Axis Won't Move (or Only Moves in
One Direction), and Other Axes Move"
(below).
Cause: PathPilot isn’t commanding the move, or there's a controller problem.
Probability How-To Steps
Low
1. Jog the axes and, from the PathPilot interface, examine the value displayed in their DRO fields. If the position
doesn't change while you're jogging, there's a problem with the controller.
2. Select the Main tab, then, on the keyboard, select the Esc key.
3. Try to jog the axes again, and examine the value displayed in their DROfields.
4. If the problem persists, restart the controller.
7.14.2 One Axis Won't Move (or Only Moves in One Direction), and Other Axes Move
Cause: There are loose wires or ribbon cables.
Probability How-To Steps
High
1. Power off the machine (see "Power Off the Machine" (page35)).
2. Examine the connection of the J6 ribbon cable and the power wires from the DC-BUS board to the affected driver.
3. Power on the machine (see "Power On the Machine" (page33)) and test for operation.
