1. INTRODUCTION
The P/A Industries Mini Servo Roll Feed is a state of the art AC Servo feed, which eases operator adjustments to feed
pitch, speed, and acceleration. These operator adjustments are entered into the control memory by keypad input. With
the use of a positional limit switch, the press signals the feeder when to begin moving the strip. The operating speed of
the press should be set to provide adequate time for the index to be completed while the die is open.
The mechanical simplicity, accuracy, and ease of use of the Mini Servo Roll Feed should help to improve your quality
and production for years to come.

The servo control acts as the central processor for the Mini Servo Roll Feed. Feed parameters entered into the servo
control are processed to position the servomotor. Calibration of the motor encoder to the feed roll circumference
allows accurate positioning of the feed roll. Each revolution of the servomotor produces 8000 encoder pulses. Every
2.857 revolutions of the servo motor shaft produce 1 revolution of the feed rollers. The circumference of the lower roll
is approximately 5.566 inches.
When a new feed pitch is entered into the system, the built-in computer calculates the correct number of electronic
“pulses” it must receive from the motor mounted encoder in order to rotate the feed rolls the correct distance.
Example: If a feed pitch/length of 5.566 inches is entered into the feeder, this will result in exactly one revolution of
the feed rolls. The motor will accelerate and turn 2.857 turns. This will produce (2.857 x 8000 = 22,856) pulses of
the encoder. The feeder will decelerate and stop when 22,856 pulses are detected. The feeder is now on position. The
3

end result is an accurately positioned strip exactly 5.566 inches from its starting point. This entire process happens in
milliseconds.
3.INSTALLING YOUR “MINI” SERVO FEED
3.1 MECHANICAL INSTALLATION
The Mini Servo Roll Feed is supplied with an adjustable mounting bracket. The feed should be securely mounted to
the press frame. (A transition bracket is sometimes required in certain applications.) The feed should be centered,
square, and perpendicular to the pass line of the press. It should be mounted at a height that will accommodate the
appropriate die sets. The feed has a pass line height adjustment of ±1.2 inches (Note: The centerline of the Feeder is
NOT the centerline of the rolls.) Refer to Figure 2 on Page 4 for dimensioning.
The feeder may be used to push or pull strip stock through the die.
If pilot locating pins are used in your die sets, the optional mechanical roll release bracket should be attached to the
press ram. It must be mounted in such a way as to provide roll release at the proper time and be adjustable for different
die sets.
If the optional electro-pneumatic piloting is used, another cam switch will be necessary for controlling feed roll
opening and closing.
3.2 ELECTRICAL INSTALLATION
The Mini Servo Roll Feed has been designed to make electrical connections quickly and easily. Simply connect the
power plug to a "clean" 115 VAC, single phase, 10-Ampere source (15-Ampere for SRF-320 model). Avoid having
other equipment share the same circuit as the feeder. The inputs and outputs to your press control (i.e. Emergency
Stop, Feed Cam Contact, Pilot Release Cam Contact) must also be connected for proper operation. The motor connects
by factory installed "Amphenol" (Military Specifications) Quick connectors.
3.3 ELECTRICAL CONNECTIONS
For more detailed wiring information refer to Electrical Schematic A-17647-11.
NOTE:
All connections should be made in accordance with National Electrical Code (NEC) requirements and must comply
with all local ordinances.
NOTE:
A word about electrical “noise”. Most pressroom environments contain considerable electrical noise. It is emitted from
electro-mechanical press relays, contacts, and solenoids. While the Mini Servo Roll Feed has been designed to
minimize “self generated” electrical noise, it is difficult to provide protection for all applications. If erratic system
behavior is experienced, then the source of the “noise” must be suppressed with either a resistive/capacitive type of
suppressor on AC coils, or “Avalanche” type diodes on DC coils.
NOTE:
The Mini Servo Roll Feed is fully protected by line circuit breakers. If it becomes necessary to replace the fuses, use
only exact equivalent fuse types to prevent serious damage to the system.
NOTE:
The electrical control enclosure is supplied with a stand-support, which may be placed in any convenient location. The
enclosure may also be mounted in any fixed location as long as the cabling is adequate to reach the feed. It is not
recommended that the electrical enclosure be mounted directly to the press. The vibrations caused by the punch press
can result in damage to the control system.

4. PROGRAMMING THE “MINI”
IMPORTANT!
Before turning the system on for the first time, verify that the main input voltage is correct (115 VAC single phase)
and inspect all connections for tightness, shorts, etc.
Plug the 115 VAC plug into a clean 10 Amp supply (15 Amp for SRF-320 model. Press the amber ‘POWER ON’
push button. The button will illuminate and the data input display will be visible. If pressing the ‘POWER ON’ push
button has no effect, then check the ‘TWIST-TO-UNLOCK’ Emergency Stop button for the ‘UP’ or ‘RELEASED’
position.
Start up screen is displayed for about 5 seconds.

5. OPERATING THE FEED
NOTE:
It is very important to remember that the motor on The Mini Servo Roll Feed System is only for feeding material. It is
not intended to be the power source for a pull-through straightening device, or the like. An adequate free loop must be
provided at all times. This will assure consistent and accurate feeding.
5.1 LOADING THE FEED
The material should be brought from the powered pay off device to the feeder. The rolls of the feed must now be
opened to accept the material. This is done by roll release lever to lift the upper roll. The maximum thickness
capability of the Mini Servo Roll Feed is .062 inches. Do not try to operate the feeder with material that is thicker than
it was designed to feed. Damage to the feeder may result.
ROLL RELEASE LEVER
MATERIAL THICKNESS ADJUSTMENT
Figure 3
With the material inserted into the feed rolls and the upper roll resting on the material, the two socket head thickness
screws should be adjusted to provide minimum “play” in the pilot release actuator arm. Tighten the lock nuts.
We presume that the feed system has been programmed with the proper Length, Speed, and Accel for the first die set.
Also, that the press has been adjusted for the current job (i.e. shut height, tonnage monitors, lubrication, speed, etc.).
The material should be jogged into position at the die set (first station on a progressive type die). Check the “free
running” of the strip in the die.
If possible, put the strip through the entire die set, open the rolls, and make sure the material slides easily in the die set.
Once the material is aligned square into the die, then the guide rollers on the inlet of the feeder must be adjusted.
These rollers should be locked into position with approximately .010 inch gap between the edge of the strip and the
roller. If the rollers are set tightly against the strip, then servo drive overloads could result.
5.2 AUTO/MANUAL MODE
When ‘MANUAL’ is selected via the 2-position selector switch, the control is put into ‘MANUAL MODE’. During
manual mode the feeder may be jogged infinitely in either direction.
Pressing ‘Cycle Start’ button, while the 2-position selector switch is in ‘AUTO MODE’ makes a servo feed ready to
accept an index signal from the press.
10
Page 11
Form 1145 Mini Installation Form and Operation Manual 02/02/2006
NOTES ABOUT "POSSIBLE PROBLEM TOOLING"
• A tight die, one that is not square, or has other tooling problems, will cause significant difficulty and
downtime. Accuracy in feeding is directly related to how easily the feeder can position the strip in the die. Binding,
bad part ejection, or sticking parts may cause the material to “jam” in the die.
• The Mini Servo Roll Feed will “try” to overcome the "jam-up" by applying more power to the rolls.
ONE OF THREE OUTCOMES WILL RESULT:
• The feed will apply more power to the rolls causing them to slip on the material. This produces a “short-feed”.
In reality, the feeder did not “misfeed”. The rolls positioned properly; the strip just did not keep up. The die then closes
producing a miss-hit.
• The feed applies more power to a thin strip causing the material to buckle somewhere between the feed and the
die set. The feeder positioned the strip accurately, it just did not occur in the die set.
• The feed tries to apply so much power to a heavy strip in order to move it, that excessive current is drawn by
the servo drive. This results in the drive shutting itself down to protect itself.
The press ram should now be “inched” down until the pilot pin is located just above the prepunched strip. The
mechanical pilot actuator on the feed should now be adjusted to open the rolls just after the pin is into the strip. (See
Figure 4.)
The ram can now be inched thru the bottom of the stroke and carefully inched up until the pilot pin or longest punch is
just clear of the strip.
Now look at the entire die set and see that it is "safe" to move the strip. If so, now is the time to set the ‘Feed
Index Cam’.
PILOT PIN
STRIP
Figure 4
NOTE ABOUT CAMS:
The Feed Index Cam (open tool): The feed system uses this press cam for timing the feeder to the press crankshaft.
Although no shafting or belts actually connect the press to the feeder, the feed must be “told” when it is safe to move
the strip.
• This “connection” is an electrical one, and not a mechanical one. This gives the operator/set-up personnel
total flexibility in deciding when the feed progression should take place.
• Each die set can have a unique ‘Feed Angle’. This ‘Feed Angle’ is dependent upon many variables; pilot and
punch length, press stroke, strip forming in the die, etc.

5.3 FEED INDEX SIGNAL
The Mini Servo Roll Feed requires one signal to control the feed indexing. This signal initiates the start of feeding,
and is usually set to occur as soon as the die is open. The duration of the feed signal should be at least 30 milliseconds
(ms). The feed signal should be ‘OFF’ at the top of the press stroke to prevent double feed indexes. (See Figure 5.)

6. PNEUMATIC PILOT RELEASE
During operations such as forming or using pilots, the purpose of the Pneumatic Pilot Release is to release the strip
from being held by the feeder rolls. This allows the material to be adjusted slightly any time during the press cycle.
The pneumatic release mechanism is mounted centrally on the top of the feeder using (4) M8 screws and washers in
slotted holes. The slots are to allow proper alignment and adjustment with the release arm and roller.
Open the rolls allowing clearance between the upper roll and the material approximately 0.010”/0.25 mm.
(Use a shim on top of the material, if needed.)
Position the Pilot Release mechanism so that with the cylinder piston fully extended against the roller.
The SRF Pilot Release mechanism is pre-assembled, only needing outside air and electrical connections. For air
connections, refer to Figure 6.
The release is operated through the 3-way solenoid valve when the appropriate voltage signal is applied. This power
signal can come from a source such as a rotary cam switch.
The solenoid valve, located on the side of the feeder body, is provided with a cable attached to the solenoid valve for
connecting the power signal leads.
Air pressure of 80-100 PSI is required for proper operation of the release. A 1/4” tubing fitting is provided
for the air supply connection.

7. MAINTENANCE
The Mini Servo Roll Feed needs very little maintenance to keep the system operating at its optimum performance.
• This precision equipment must be kept as clean as possible. This is especially important if large amounts of
air suspended oil mists in combination with “dirty metals” are used. The resulting abrasive dust can attach itself to the
feed rolls and other surfaces, leading to premature wear on many parts.
• The roll release system requires a clean, dry air supply.
• Some bearings used on the feeder are fully sealed and maintenance-free roller ball bearings. The exceptions
are provided with standard “zerk” type grease fittings. They should be lubricated with a good grade of high pressure
bearing grease. The frequency of lubrication will depend on the overall usage of the system. A small “shot” once a
day is a good starting point. The cluster gear set should be coated with a small amount of open gear grease.
• The main drive belt should be checked periodically for tightness. It can be adjusted by loosening the three
fasteners on the motor adjuster plate, applying downward pressure on the plate, and retightening. ERRATIC MOTOR
BEHAVIOR WILL BE EXPERIENCED IF THE DRIVE BELT IS LOOSE!
• All fasteners should be checked for tightness at regular intervals. The electrical system also requires very little
maintenance. Keep the enclosure clean and replace any burned indicator bulbs. Do not expose the electrical enclosure
to constant high temperatures. Possible system failure could result.
• The Feeder’s electrical enclosure door is sealed to prevent oil and contaminants from entering inside.
However, small gaps can be found around some sealing surfaces and faceplates. It is a good idea, therefore, to keep the
console free of stamping oils and fluids, which could "seep into" the enclosure. Most often these oils are carried by the
operator’s hands or by air mist lubrication etc.
• All of the above guidelines should be added to your existing pressroom Preventive Maintenance
(PM) Program.

WARNING
This equipment offers various means of operating or controlling machines. The operator must not be in or near the point-ofoperation of the machine, or the operating parts of any equipment installed on the machine, or bodily injury could result. The
EMPLOYER must post adequate warning signs onto the machine with proper warnings for his machine and the specific
application to which the machine and equipment are being applied.
Occupational Safety and Health Act (OSHA) Sections 1910.211, 1910.212, and 1910.217 contain installation information on the
distance between danger points and point-of -o perat io n g uar ds a n d devices. No specific references have been made to which
paragraph of OSHA 1910.211, 1910.212, 1910.217 or any other applicable section s because the paragraphs may change with each
edition of the publication of OSHA provisions.
All equipment manufactured by us is designed to meet the construction standards of OSHA in effect at the time of sale, but the
EMPLOYER installs the equipment so the EMPLOYER is responsible for installation, use, application, training, and maintenance,
as well as adequate signs on the machine onto which this equipment will be installed.
Remember, OSHA says that the EMPLOYER must use operating methods designed to control or eliminate
hazards to operating personnel.
It shall be the responsibility of the EMPLOYER to establish and follow a program of periodic and regular inspections of his
machine to insure that all their parts, auxiliary equipment, and safeguards are in a safe operating condition and adjustment. Each
machine should be inspected and tested no less than weekly to determine the condition of the machine. Necessary maintenance or
repair of both shall be performed and completed before the machine is operated. The EMPLOYER shall maintain records of these
inspections and the maintenance work performed.
Our Company is not responsible to notify the user of this equipment of future changes in State or Federal laws, or construction
standards.
SAFETY PROGRAM
Accident free operation will result from a well developed, management sponsored and enforced safety program. Of vital
importance to any successful program is the proper select i on of gu ards and devices. However, there is no safety device that will
bring “automatic” safety to your operation.
Of equal importance to this proper selection of the guard and the device is the training of your personnel. Each person must be
trained as to the operation of the guard or safety device, highlighting why they have been provided on the equipment. Rules for
safe operating should be written and enforced at all times. A final major concern of an effective safety program is regularly
scheduled inspection and maintenance of all of the equipment.
To ensure continued safety at all times, top management, line supervision, safety engineers and all employees must assume their
proper share of the responsibility in the program. Only as a group, one that knows your own operation and its problems, can you
carry out an effective safety program.
To assist you in the development of and continued use of safety programs, many safety minded groups have made guidelines
available to you. However, you must know when and how to apply these guidelines. The manufacturer provides information to
assist you in properly adjusting and maintaining your equipment. There is no short cut to proper safety; therefore, it is
recommended that you comply with their recommendations at all times.
