Are the Cables
damaged?
Visually inspect the following
cables for damage.
X-axis Linear Encoder Cable
(P/N 194985, top) and Y-axis
Linear Encoder Cable (P/N
194986, bottom) connected to
the XY Servo Interface PWA at
connection J23.
Manually verify that the X and Y-
axis Linear Encoder Cables are
securely connected to the XY
Servo Interface PWA at J23.
Are Linear Encoder
Cables securely
connected?
Visually inspect for damage the
Rubber Seal that runs the length
of the guide of Linear Encoders.
Are the Rubber Seals
of the Linear Encoders
damaged?
Using Linear Encoder Alignment
Tool (P/N 194983), check correct
gap between Linear Encoder
Guide and Reader.
Using Linear Encoder Alignment
Tool (P/N 194983), check correct
alignment between Linear
Encoder Guide and X-axis Beam.
Cable(s) (P/N 194985,
194986) have failed
No

Are the Linear
Encoders in need of
adjustment or
alignment?
Go to X-Axis Linear
Encoder Verification
Go to “Adjusting Linear
Encoder Gap” in Module 2.
