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.
