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.
