Functional Description
The dual X-Y positioning system contains the X and Y positioning tables
which are actuated by the servo drive motors. When the motors receive a
signal they move the positioning system to predetermined coordinates con-
tained in the pattern program. Rotary encoders monitor the positioning sys-
tem location to ensure the positional accuracy. The X and Y tables mount on
the base and position the dual rotary tables.
Maintenance Concept
The following table defines the recommended Maintenance Concept for this
assembly. For a more detailed explanation of the Maintenance Concept and
its structure refer to the Prerequisite Information/Introduction module and the
periodic preventive maintenance as presented on page 49 of this document.

Rotary Disk Alignment
Purpose:
The rotary disk alignment proceduret aligns the rotary disk to the X axis
table.
Several associated assemblies rely on one another. If one assembly is ad-
justed, the rest are affected. It may be necessary to alternate between one
step of the procedure and another several times until the rotary disk is
aligned.
Read the entire rotary disk alignment procedure before attempting the
adjustment.
Rotary disk alignment is correct when, with the rotary disk locked in the
FRONT position, the dowel pins can be inserted and removed by hand
through the rotary disk and into the X axis table.
Due to the tolerance build up, interference may be felt when inserting
and removing the pins. This is normal and in no way means the table is
not properly aligned. If the pins can not be inserted into the holes with
force, the disk is not properly aligned.
After the rotary disk is aligned, the two locator pin assemblies drop into
their corresponding locator holes. The additional pressure exerted by
the lock assembly may cause the rotary disk to shift. This shift prevents
the insertion or extraction of the guide pins and additional adjustment of
the lock assembly is required.
If the locator pins slide into the holes after the lock and drive
assemblies are in position, alignment is correct. Proceed to the X-Y
axes encoder adjustments.
Machines with Board Handling System have two low profile guide
wheels which require a special wrench and procedures. These
differences are noted as applies in the following procedure.

Special Tools:
Torque Wrench (in./lbs.)
Torque Gage (in./oz.) (46808001)
(Waters Mfg. model 651C-30)
Torque Adapter (45081601) (High profile guide wheels)
Dowel pins (1/4 x 2) (80010109) with collars (18333000)
Wrench (46758401) (Low profile guide wheels)
Adjustment Procedure:
Depending on the machine configuration, covers and/or assembly
components will have to be removed to allow access to the guide
wheels and drive assembly.
1. Remove the four stop blocks from the rotary disk
2. Remove the two socket head cap screws from the stop plate on the
drive assembly.
3. Remove the stop plate from the drive assembly to remove the drive
wheel pressure on the rotary disk.
4. Assemble the locator pin assemblies using dowel pins and collar
clamps.
5. Insert the locator pin assemblies through the locator holes in the rotary
table and into the locator holes in the X axis table as shown.
