RECEIVING INSPECTION
Before removing unit from its packaging, check for visual damage, especially if crate, skid, or carton has been
damaged in transit. Any damage caused by shipping should be immediately reported to the carrier. If unit appears in
satisfactory condition, remove all packing and wipe rust preventive from rollers with mild solvent.

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

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.
