FloPro, October 2, 1995
This revision was installed on the lab machine on October 2, 1995. This revision was to implement Low
Coolant Grind Abort, Chuck Stopped Grind Abort, support Retain Chuck in Use Status, eliminate a
redundant clean cycle during dual grind, support single chuck operation for dress/true, and provide support
for a light tower. A new version of FloPro runtime software is being used to reduce memory requirements. A
new debug version is also included.
7AF Version 2.04 Features
10/13/95 Ken Hill
Purpose
Software version 2.04 for the model 7AF is release that incorporates many new features and fixes. This
software must use a new probe control card, the Heidenhain IK121 (SYMIX #223581)! Please review all
of the following descriptions before installing the new version.
This version departs from previous upgrades in that it includes a complete set of updated files that will
replace all existing software to run the 7AF. If for any reason you may want to return to the old version, do
a complete backup of the directory \7AF\EXECODE to a separate directory on the hard drive or backup to
floppy disk. Robot macros must be version 2.03! All FloPro flowcharts and supporting files (.UAI) are
included. All Graphics files (.GRS) are included.
Bug Fix from version 2.03
One change in this version is a bug fix that could prevent the completion of the dress or true wheel cycle. The
symptom is that the process will hang on one of the steps and not progress to the next step. This is due to
protections installed to disallow any moves until proper status is returned. This version prevents a Z axis
move attempt in the dress cycle until the axis has come to a complete stop.
Also a similar fix was installed in the reference cycle that could report an "ERR110" and "SERVO FAULT".
7AF Version 2.05 Features
1/24/96 Ken Hill
Purpose
Software version 2.05 for the model 7AF is a release that incorporates many new features and fixes. The
primary changes are in improved robot status handling. This software must use new Robot Macros, version
2.04!
Robot Status Improvements
One of the major improvements in this version of the software is that robot status is controlled much more
tightly. Also, status is displayed on the screen whenever it is updated by the program. Fixed portions of the
status are checked constantly and a status request is reissued if it is ever found in error. These changes should
eliminate any spurious faults from bad status. Communication routines were improved to greatly increase the
reliability of the status information, also.
A robot servo error will now disable all bridge moves. Therefore, if there is a robot servo error being
reported, this error must be cleared before using the bridge.
The new robot macros leave the theta axis activated while placing wafers into the receive cassettes. This
means that the robot must be aligned properly at the receive cassettes. Improper alignment can result in the
cassettes being jostled or a servo error and turning the robot servo off. This change will result in improved
control when placing wafers and less chance of undetected servo errors occurring.
