User Manual
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 11.142 inches is
entered into the feeder, this will result in exactly
one revolution of the feed rolls. The motor will
accelerate and turn 2.909 turns. This will produce
(2.909 x 8000 = 23,272) pulses of the encoder.
The feeder will decelerate and stop when 23,272
pulses are detected. The feeder is now on position.
The end result is an accurately positioned strip
exactly 11.142 inches from its starting point. This
entire process happens in milliseconds.
3. INSTALLING YOUR
ADVANTAGE SERVO FEED
3.1 MECHANICAL INSTALLATION
The Advantage 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 Advantage Servo Roll Feed has been designed
to make electrical connections quickly and easily. All
that is required is a "clean" 220 VAC single phase
20 ampere source. The inputs and outputs to your
press control (i.e. Emergency Stop, Feed Advance
Cam Contact, Pilot Release Cam Contact,
Continue Cam Contact, End of Strip Input) must
also be connected for proper operation. The motor
connects by factory installed "Amphenol" (Military
Specifications) Quick connectors.

NOTE:
All connections should be made in accordance
with National Electrical Code (NEC)
requirements and must comply with all local
ordinances.
IMPORTANT!
A #12 MTW grounding conductor must be
installed for proper machine grounding.
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 Advantage
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 Advantage Servo Roll Feed is fully
protected by line fuses. 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.
3.3 ELECTRICAL CONNECTIONS
For more detailed wiring information refer to
Electrical Schematic A-17556-01 for 220 VAC and
Electrical Schematic A-17556-02 for 440 VAC.
The main power for the feed system requires a
"clean" 220 VAC single phase 20 ampere source.
A terminal strip is provided in the main control
enclosure to facilitate wiring connections. It is
recommended that #12 MTW (Machine Tool Wire)
be used for the primary power supply input.
