yoke
properly.
Yoke loose in the
carriage
Inspection for any motion of the yoke or looseness in the Yoke mounting screws.
Oil lines sheared
Visual inspection.
Oil line blockage
Pump the oil and ensure that it flows evenly to the ways, ball screws and cross-slide.
Z Ball screws not
aligned properly
Manually turn the ball screw through the length of its travel. Pay particular attention
to the movement near the headstock, the middle and the tailstock.
NOTE:
Ball screws are inspected throughout their entire travel for backlash and consistent torque. A ball
screw should be good for millions of inches of travel if installed properly. Do not be too quick to replace a
ball screw if there is insufficient indication that it is bad; this will just be a costly delay to resolving the real
problem.

4.3 Pendant and Computer Module Diagnostics
The following table lists some problems and what these problems can lead to.
Possible problems
Can lead to
Poor cable connections
There are 2 cable connections on the rear of the
pendant. This is the Ethernet cable and I/O cable
(ends with a DB25 connector). Make sure both cables
are properly fastened on both the Pendant and the
Computer Module
Pendant locks up
On the rear of the Pendant, identify the “Key Press”
LED (third from the top of the right LED group). Press
a numerical key and confirm the LED turns on when
the key is pressed. Turns off when the key is no
longer pressed. This confirms the software is running.
Press the E-stop button and see if lock up clears if not
then do the following:
Turn the pendant off (remove power from the
computer module), wait at least 30 seconds, and
connect power back to the computer module. Check
to see if the malfunction has been remedied.
Low voltage or power problem for the
pendant.
Can cause the system to lock up, RSG to fail and the
flash drive to act abnormally.
Refer to the diagnostic LEDs on the rear of the
Pendant. The three power LEDs (+5VDC, +12VDC
and +24VDC) should be on.
If not, ensure the cables on the rear of the pendant
are securely connected to both the pendant and
computer module. Ensure power is supplied to the
computer module.
Possible problems
Can lead to
Flash drive failure
If the flash drive fails, all programs and machine
