A. TAUT STOCK INPUT (J52)TBI-3)
This is a normally open contact from
a switch or device that monitors the
loop of material prior to the servo
feed. When the material reaches a
point that it trips the switch, a taut
stock has been reached. This input,
when received, immediately drops
the automatic which stops the feed
in progress. The material should
be repositioned in the die before
restarting the automatic sequence,
as the progression was lost when
the taut stock occurred.
This input also could be used as a
“No Stock” switch that would monitor
whether or not there is material
available to feed.
B. ENABLE INPUT (J4-Pin 5 & 6)
The enable input is shipped from
the factory, jumpered, so that the
Pac-Sci unit is ready to work after the
initialization procedure is complete.
If it is desired that the servo controls
are not functional until other
equipment or safety source is activat-
ed then a normally open contact can
be interfaced to this input. If at any
time during the feed cycle the input
changes state then the feed will stop
at this position. If feeding stock, the
reference will be lost and the stock
will have to be manually repositioned
to the correct location. The automatic
cycle will be dropped and have to
be restarted.
C. ENABLE OUTPUT (J52)TB2-22)
This output must be tied to a solid
state relay to interface to the outside
world. The solid state relay must
have a D.C. coil and should have a
rating of 3-30 VDC. The Rapid-Air
#69100165 is recommended for this
application. This output is high
whenever the enabled input
is activated.
D. PRESS OUTPUT (J52)TB2-21)
This output must be tied to a solid
state relay to interface to the outside
world. The solid state relay must have
a D.C. coil and should have a rating
of 3-30 VDC. The Rapid-Air #69100165
is recommended for this application.
This output goes high at the end of
every feed cycle and stays high for
programmed press time before going
low. To adjust this time, go to
programming the job number and
adjust the time needed for the press.
E. AUTOMATIC OUTPUT (J52)TB2-20
This output must be tied to a solid
state relay to interface to the outside
world. The solid state relay must have
a D.C. coil and should have a rating
of 3-30 VDC. The Rapid-Air #69100165
is recommended for this applica-
tion. This output goes high whenever
automatic is selected on the program
panel. Any faults will cause the auto-
matic output to go low.
F. KEYPAD AND DISPLAY
INTERFACE (RS232 PORT)
The keypad/display is the interface
between the operator and the resi-
dent program. The Pacific Scientific
drive is purchased with a great many
capabilities, none of which can be
used unless a program is written to
utilize these capabilities. Rapid-Air
put a great deal of time making a
program that is user-friendly and yet
gets the job done efficiently. We took
all the questions and constructive
criticism and came up with a program
that would cover all the applications,
yet be easy to interface and program
by a customer.
If an operator reads the programming
procedure in this manual and then
reads the screen parameters listed
as they are displayed and acts on
them by inputting data as needed,
the servo can be up and running in
a very short time.
1. Select a job number.
2. Input or review parameter for
that job number.
3. Thread up material in manual
mode.
4. If properly interfaced, go into
automatic mode.
