Rapid-Air Introduction to MS-Series
The MS-Series servo has many
features found in the more expensive
models. Some of its features are:
Input:
120 VAC, 50/60 Hz
Amperage required at input:
10 amps maximum
Accuracy:
.0025 per feed length at the rolls
Maximum feed length input:
999.999 inches
Job storage:
99 jobs
Display:
4 rows by 80 characters, backlit
Note:
Fault type:
Displayed on the drive if a fault
occurs otherwise an “8.” is
displayed.
Rolls:
Hardened and ground.
Drive roll parallelism adjustment:
Used to tune the rolls to the
material if needed.
The Rapid-Air MS-Series feed uses
the same type of programming
procedures as it has in its more expensive models. Input a feed length,
strokes per minute, and a feed arc
and the program will adjust the servo
acceleration/deceleration and maximum servo speed parameters to the
requirement needed to keep up to the
press strokes per minute.
The precision mechanical roll feed has
been designed for compactness, ease
of setup and installation. A 120 VAC
receptacle is all that is required of the
customer. Two cables are supplied with
the control and need to be connected to
the proper locations of the motor. The
electrical controls are housed in a small
box that can be mounted on the press
or if purchased, on a post that can be
positioned close to the press.
4 keys were chosen to have a double meaning,
arrows and “F” keys. The arrows were brought out
as the primary instead of the “F” keys. If you would
bear with us, we are looking at a correction.

Installation
The Rapid-Air servo was run and fully
tested before being shipped from our
plant. Carefully inspect all parts when
uncrating them. If you find any damaged parts, please report it to the carrier that delivered the servo drive and
at the same time, report the damage to
your distributor.
The servo feed container should
contain:
1) servo feed – standard
1) console – standard
Roll Pressure
The roll pressure knob is located on the
entrance side of the feed and is a knurled knob with a locking nut located
right behind it. It is positioned parallel
to the inlet face and uses a compression spring for adjusting roll pressure.
1) console stand – optional
1) servo mounting bracket – optional
1) cascade roller assembly – optional
Please contact someone at your
facility to verify what options you
purchased.
If a mounting bracket was purchased,
then it should be mounted first
being careful that the center line of the
bracket lines up with the centerline of
the die area. The servo can then be
mounted on the bracket. A print of the
bracket can be found in the back of
this manual.
If a bracket was not purchased,
then the servo will have to be mounted
on the press bed or customer
provided bracket. Line up the rolls
to be centered and perpendicular
to the center line of the die area.
Included in the back of this manual
is a hole pattern layout print for the
MSA2 servo.
Roll Release Handle
The roll release handle is located on the side of the feed. Lifting the handle
opens the rolls and lifting to its stop will lock the rolls in place. This is a true
statement if the pilot release stop is not set. If the stop is set, then the roll will
only raise until the stop is reached just like in automatic for pilot release.
Gear Box
The gear box is located within the
feed body on the same side as the
roll release handle. It has a nonlubricated gear box so it is essentially
maintenance free.
Electric Pilot Release
The optional electric pilot release can be mounted on the entrance side of the
servo at the place labeled “inlet.” It is the customer’s responsibility to interface
the pilot release valve with the customer supplied, press-mounted, activating
switch. The air requirements for the release to work correctly is 80 to 120 psi,
dry filtered and lightly lubricated air. There should be a minimum of 2 CFM
available at all times.

Feed Rolls
The rolls are case hardened and
ground solid rolls which make them
good for profiling, if you are running
a part that would need clearances
ground into the roll. Useful information that you might need in the future
is that one revolution of the rolls is
3.173 inches. This can be used to
check if the program and motor are
working correctly. Put a line on the
lower roll and program the feed to
feed to feed 3.173 inches. The line
should return to the same spot after
every feed. If it does not, then call
Rapid-Air. If it does, then something
in the setup, such as roll pressure
or an obstruction in the die, could
cause a short feed.
Pilot Release Stop
A pilot release stop may be added for higher speeds. The pilot release stop is
mounted next to the roll pressure knob and should be set to let the rolls open
about .005/.010 to free the material during piloting.
Adjustable Entrance Guide
The adjustable entrance guide is an add-on feature that can and should be used
on the entrance and exit of the servo feed. It has screwdriver slotted adjustable
stops for quick stop adjustment. By having one on each end of the feed, the set-up
time for aligning the material in the feed is decreased considerably as you will
now know that the material is straight through the feed before entering the die.

Operator Input Section
The intent of this section is to familiarize the operator with the flow of the
program and what to expect with each
key press. Each program screen of
the servo will be displayed and also
comments to clarify possible questions.
There are four sections that will be
explained and they are as follows:
SECTION 1 —
JOB NUMBER
SECTION 2 —
MANUAL MODE
SECTION 3 —
AUTOMATIC MODE
SECTION 4 —
REVIEW JOB PARAMETERS
When the servo is first started, and
has performed its startup procedure,
the first screen displayed should look
like this:
MAIN SELECTION MENU
F1=JOB NUM F2=MANUAL
F3=AUTOMATIC (CYCLE)
F4=REVIEW PARAMETERS
*SELECT F1=JOB NUM
The first step in programming a job is
to select a two digit job number which
will be used to store the parameters
that the operator inputs or to recall
an existing job number that was
previously loaded. When the operator
presses F1 on the keypad, the screen
will change to:
JOB SELECTION MENU
ENTER JOB NUMBER=_____
PRESS F4 KEY AFTER
CORRECT # IS ENTERED
The next screen lets you program
parameters or exit with the existing
parameters.
JOB NUMBER= _____
F1=PROG. PARAMETERS
F4=DON’T ALTER VALUES
Pressing the “F1 PROG. PARAMETERS”
key initiates the following screen.
Key in the required parameters.
FEED LENGTH= _____
PRESS SPEED= _____
FEED ANGLE= _____
* Once the parameters have been
entered, the program will complete
the math routine which selects the
proper accel./decell. and motor speed
for the parameters listed and then the
main menu is displayed again.
* SELECT F2 MANUAL
If the operator elects to move the
material from the feed to the die
electrically, the manual mode has to
be selected. Pressing the F2 key will
bring up the manual mode screen.
MANUAL LENGTH= _____
F1=SINGLE _ FEED
F2=GO TO INCH MODE
F4=RETURN
Each time the F1 key is pressed,
the servo will move the material
the feed length entered for the job
number. The material will move at
the speed required to keep up
with the programmed press strokes
per minute.
If the operator would like the material
to move a slower rate then the inch
mode should be selected. Press F2
now to display the inch mode screen.
INCH MODE:
F1=JOG FORWARD
F2=JOG REVERSE
F4=RETURN
When the F1 key is pressed, the feed
will advance the material at a slow
rate of speed. When the F2 key is
pressed, the feed will reverse the
material and run at a slow rate of
speed. Press F4 to return to the
main screen.
With the main menu displayed
and pressing the “F3 AUTOMATIC
(CYCLE)”, the following screen
appears:
AUTOMATIC JOB=01
FEED LENGTH= _____
PRESS SPEED= _____
F4=RETURN
In the automatic mode, the feed
length and operator entered press
speed will be displayed. Whenever
the press mounted feed switch is
activated, the servo will feed the
feed length displayed on the screen.
Because there is not an interface in
the control for the pilot release it will
be up to the customer to wire the pilot
release switch to the solenoid that
operates the raising of the rolls.
Press F4 button to return to the main
menu and deactivate the automatic
control.
Press F4 again and the final mode is
review parameters, the parameters
for the job number will then be
displayed.
