SERVO INTERFACING EXPLANATION
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 and also drops the automatic output. The material should
be repositioned in the die before restarting the automtaic sequence, as the progression
was lost when the taut stock occurred. If the automatic output was tied to a safety device
that top stopped the press at the same time then the press will have to be restarted also.
This input also could be used as a “No Stock” switch that would monitor whether or not
there is material available to feed. An opposite type contact would have to be used as the
processor input is looking for a contact closure to complete the circuit.
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 activated 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 OUPUT (J52)TB2-22)
This output must be tied to a solid state relay to interfact to the ouside 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. END OF FEED 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 and stays high for programmed amount of time before going low. To program the
time, with the main screen menu displayed, push the period on the keypad - follow the
instructions and enter the time in milli-seconds. The time entered will add to the total feed
cycle time and if programmed to last longer than the time from the actual end of feed and
the actual tripping of the feed switch then the program will not see the feed switch being
tripped. You will then get two hits per feed.
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 application. This output goes high whenever
automatic is selected on the program panel. Any faults will cause the automatic ouput to
go low.
