Rapid-Air SMART MINI-SERVO FEED CUT-TO-LENGTH: SMS2, SMS4, SMS8 - Manual (Page 4)

Every servo feed has an eccentric
adjustment screw to adjust the upper
roller to be in parallel to the lower
roller. The maximum adjustment is
.008” on the eccentric.
The adjustment screw is located
opposite the belt cover and is held
fast by a socket head cap screw.
The actual adjustment screw is an
eccentric sleeve which is turned
clockwise or counter-clockwise to
raise or lower one end of the upper roll.
The parallel adjustment is factory
set when the unit is manufactured
but if material tracking seems to be a
problem then this could be a way of
solving the problem. To test if the rolls
need adjustment, do the following.
1. Remove the front and rear roll
covers.
2. Shine a light from the rear
of the feed toward the
main rollers.
3. Inspect from the main rolls
side to see if the rollers are
parallel. If they are, then the
material could be the cause
of the material walking. If
they are not parallel then an
adjustment has to be made.
4. To make the adjustment:
a. Locate eccentric screw
and loosen socket head
lock screw.
b. Turn slotted eccentric
sleeve while viewing rolls
until the rolls are parallel.
c. Tighten 10-32 screw and
reassemble parts, then retry
running material.
adjustment, cabling and interfacing
For a more accurate adjustment use a
feeler gauge to check the parallelism.
This completes the eccentric adjust-
ment write-up, if there are further
questions, please call the factory.
* Before attempting to solve a
possible roll parallelism problem by
readjusting the rolls or calling the
factory, perform the following test.
Step 1) A 3 to 5 foot length of material
should be cut from the storage loop
preceding the servo feed.
Step 2) Lay the material next to a
straight line to see if the material
is cambered. If it is, then this could
be the reason that the material
is walking. If not, then turn the
material upside down from the way
it was being fed and insert into the
feed. If the material walks in the
opposite direction then the material
could be to blame.
120 VAC INPUT
The input voltage to the control is
120 Vac, 1 Ph, 60 Hz. The max
amperage needed is 7.5 amps and
the control has a circuit breaker
with a trip amperage of 10 amps.
The electrical control enclosure is
shipped completely ready to be
connected to the mechanical feed.
Connected to the enclosure are (2)
cables with keyed screw type
connectors for connection to the
motor. The third connector is used to
interface the cutter to the controls.
Position the electrical enclosure
at a convenient location near the
mechanical feed and attach the
cables. The motor cables are easily
identifiable by the amount of pins in
the plugs. The solenoid cables, if
any, can now be attached and
checked for proper location when
the feed is up and running.
An air line must be connected
from the shop air to the air inlet
of the servo feed. The air should
be at least 80 PSI continuous and
should be dry filtered and lightly
lubricated for the best operation
of the servo feed. The air inlet
is NPT pipe tap. The minimum
air line size requirement is 1/2” ID
hose. - (2 CFM)
The Servo Drive unit is programmed
to feed each time a signal is received
from the cutter switch. The servo will
feed one progression and wait for the
next signal before it will feed again in
automatic mode.
The command is in the form of a
normally open contact from a proxim-
ity switch, located on the cutter and is
activated when the cutter is returned.
If the feed/cutter was purchased
complete, then the interfacing was
done for you.
This completes the initial setup of the
servo feed to the cutter or other device.
The servo is now ready to run as intended.
