7-14 Changing the Personality
57: Z head identification code. Must be 0 or 128, factory 128.
Must contain the I.D. code of the Z head being used since wiring to the Z head for
automatic identification has been changed to implement the retractable height sensor. 128
is used for 1 mil Z heads and 0 is used for 2 mil Z heads.
58: Calibration map code for square or rectangle. Must be either 0 for square or 1 for
rectangular, factory 0.
Allows a special rectangular calibration map to be used with DispenseJet products only.
59: Paused Digital Outputs, range 0-255, factory 0
This parameter will cause the dispensing valve to be shut off if the machine is PAUSED
from the front panel or if a PS command is received. The value must be set to a non-zero
value whose bits correspond to the digital output bits to be turned off. When the machine
pauses, this command effectively turns off a valve that was turned on by the Fluidmove
zfast dispensing function. The valve will not be turned back on when the machine is un-
paused. If PE 59 is 0, no output changes will occur when the machine is PAUSED from
the front panel or a PS command is received. PE59,2; would be the typical value used for
this feature but other bits could be used if a non-standard valve or two valves are used.
Non-specified bits will not be affected.
60: Interlock Control, range 0-255, factory 0
Automove systems use a two processor architecture (8085 IOP and 6803 VGP) that utilize
“pipelining” to increase speed. This means that the IOP can serve a new ACL command
and pre-process it while the VGP is executing the previous command. Each time a new
command is sent from the IOP to the VGP, the machine’s digital inputs and front panel
buttons status is transferred from the VGP to the IOP. This causes the IOP to become
“aware” of any interlock download sequence requests AFTER a command is sent to the
VGP. Thus, while making the first move of two back-to-back moves, if the VGP detects a
digital input request for an interlock download sequence, the IOP will not become aware of
this state until AFTER the VGP receives the second move command. All commands are
processed to completion except the STOP request. Normally, two back-to-back XY moves
serve no purpose and should be avoided. However, Fluidmove can currently send two
back-to-back XY moves during spiral fills, and a pending interlock download sequence
will not occur until the second move finishes.
If personality parameter 60 is set to 1, pipelining will be disabled and the IOP will
automatically get new VGP status after an MA or MR command is issued BEFORE issuing
a new VGP command. This allows an interlock to occur between moves without both
moves completing first as previous firmware versions required. HOWEVER, this change
effectively reduces throughput since it disables pipelining. If personality parameter 60 is
set to 0, interlock actions will remain the same as version 3.59 EPROMS, but there will be
no reduced performance.
