Rapid-Air SMART MINI-SERVO FEED CUT-TO-LENGTH: SMS2, SMS4, SMS8 - Manual (Page 5)

Now that your servo/cutter combina-
tion is in place, and the cables have
been attached, you can proceed
with testing the unit. The first step
is to turn on the main switch on the
electrical enclosure.
At this time the display should show
the Rapid-Air screen for 5 seconds
before starting the main setup pro-
gram. If you are comfortable with
programming a job then continue, if
not, please refer to the Operator Inter-
face Terminal located in this manual.
Follow the programming sequence
for the operators terminal to input
parameters into job storage. Your ser-
vo feed has been fully tested before it
was shipped to your facility and this
procedure is merely a test to insure
that all functions are still functional
and the cables are properly seated.
Once you have programmed the
required parameters, select the
manual mode of operation. If the
option of air regulated upper feed roll
was purchased, check that the main
air is at least 80 psi and check that the
roll pressure gauge is functional by
adjusting the pressure up and down,
this is accomplished by turning the
pressure adjusting knob. Check that
you have enough tension on the
material to avoid slipping during
feeding. Open and close the feed rolls
manually. Visually inspect that the
rolls open and close when using the
manual levers.
Select the “inch” function (F1 on
keypad) on the manual mode screen.
Visually check that the rolls rotate
both forward and reverse with the
corresponding key. The speed is pre-
set to creep the rolls at a slow speed
for manual positioning of the material.
CAUTION: Do not attempt to place
your fingers or any foreign material
into the rolls. Injury to the operator or
damage to the servo rolls could result.
After you have verified that the
rolls are operational, you can experi-
ment with the single cycle moves.
The procedure is outlined in the
programming section of this manual.
After all the checks have been made
and you feel comfortable with the
programming of the servo controller,
place the servo in automatic mode.
Now cycle the press in either the
inch, single stroke or continuous run,
the servo feed should react upon
the closure of the press window
and signal and simulate a feed
progression of material.
Pretest and loading material
Pretest For Servo Feed And Cutter without Material
Upon the satisfactory completion of all
the tests, you should be ready to load
a strip of material into the servo feed.
Step number one is to select the
manual mode of operation on the
operators console. You open the
rolls manually by lifting the lever
mounted on the side of the servo
feed. Position the leading edge of
the material with the center of the
material near the center of the entry
rolls. Adjust the edge guides on the
cascade rolls to the proper width
setting. Open the feed rolls. Hand
feed the material into the servo unit
until it protrudes out of the feed rolls
Loading Material Into The Servo Feed
and starts into the guide on the cutter.
Close the feed rolls.
Check the roller force pressure to be
sure that there is enough pressure
to prevent slippage but not too much
to induce camber into the material.
The pressure setting is the amount of
force necessary to move the material
into the press at the speed and
feed programmed. You may find it
necessary to readjust the force as
you finalize the setup procedure. The
amount of force needed will vary
depending on the width and type of
material being fed. Make a note of the
final setting to aid in the setup of the
servo feed the next time the same
material is run.
You are now ready to begin testing
the complete system under power.
To check the progression, cycle the
servo and cutter first in the manual
mode then in the single cycle mode.
If the progression is correct, no fur-
ther adjustments are necessary. If the
progression is either short or long, go
to the troubleshooting chart and per-
form the sequences described there
for inaccurate feeding, once the feed
progression has been accurately set
and the repeatability is satisfactory,
you are ready for full automatic mode.
