Rapid-Air SMART MINI-SERVO FEED CUT-TO-LENGTH: SMS2, SMS4, SMS8 - Manual (Page 3)

The Rapid-Air Servo Cut-To-Length
Feed system carries with it the
quality and reliability you have grown
to expect from a Rapid-Air product.
The motion control system is a
programmable industrial computer
and this advanced technology,
combined with a highly engineered
precision roll feed, is an unchallenged
combination in the press industry.
The compact mechanical package,
direct coupled with a brushless servo
drive motor, offers response and feed
speed accuracy unparalleled in any
other powered roll feed. Operator
interface is so simplified, a typical
setup person can have the servo
feed programmed and running in a
matter of minutes. A step by step
prompt appears on a four line
80-character display, which asks

or reverse at a slow rate. The operator
can select jog to length or jog continu-
ous to aid in threading up material.
The Rapid-Air Servo Roll Feed has
been designed to mount on a
free-standing table as close as
possible to the cutter.
The precision mechanical roll
feed unit has been designed for
compactness, ease of setup and
installation. Three cables with twist
lock connectors, two cables for the
servo, one connected to the cutter,
and one air line are the only external
connections required. The electrical
controls are housed in a small cabinet
which should be mounted close to
the press working area. The operator
keypad and display are mounted on
top of the control cabinet.

Entry of feed length, cutter dwell time,
and % maximum speed are all that is
required for a new setup. Routine jobs
can be stored, recalled, changed and
saved or run with a simple 2 digit job
number entry. Up to 99 jobs may be
stored and recalled at will.
A resolver, direct coupled to the
servo drive motor for precise digital
position feedback, enable roll
positioning accuracy to +/- .0025 for
any programmed feed length or speed.

If you purchased the servo/cutter
combination already mounted on a
base then the servo and cutter were
aligned at the factory. A good
practice is to check all hold down
bolts to be sure that they did not
come loose during shipment.
If you purchased the servo and cutter
and are going to mount it on a base
at your facility, then a base should
be selected that will hold the weight
of the servo and the cutter and also
the cycling shocks incurred during
production.
When mounting the two devices,
the pass line height of the cutter
and the servo roller center line should
be equal. Even more critical is the
parallelism between the two devices.
The cutter should be mounted first
then the servo center line should
be aligned to the cutter center line
with the servo rollers parallel to the
cutter blade.
The servo should be mounted as
close to the cutter as possible and de-
pending on thickness of the material
a bridge should be installed between
the servo and cutter to minimize
material droop or buckling during feed.
