1 INSTALLATION
1.1 MECHANICAL INSTALLATION
The Ultra 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 1 for dimensions.
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.

1.2 ELECTRICAL INSTALLATION
The Ultra 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 15-ampere source that must be connected to the main disconnect switch. It is recommended that #12 MTW (Machine Tool Wire) be used for the primary power supply input.
The inputs and outputs to your press control (i.e. Emergency Stop, Feed Cam Signal, Pilot Release Cam Signal, Reset Cam Signal) must also be connected for proper operation.
Note, that if your feed is supplied with P/A PLS (Programmable Limit Switch) you don’t have to wire Feed and Reset Cam signals.
The motor connects to the electrical control by factory installed "Amphenol" (Military Specifications) Quick connectors.
The optional PLS connects to the electrical controls by factory installed Military Quick connector.
The optional Strip Encoder connects to the electrical control by factory installed Military Quick connectors.
For more detailed wiring information, refer to Electrical Schematic:
A-18164-01 – UltraAdvantage-US-standard;
A-18164-02 – UltraAdvantage-CE-standard;
A-18164-03 – UltraAdvantage-US-with step-down transformer;
A-18164-03 – UltraAdvantage-CE-with step-down transformer
.
A-18164-14 – UltraAdvantage-US-with Strip Encoder.
IMPORTANT!
A #12 MTW GROUNDING CONDUCTOR MUST BE INSTALLED FOR PROPER MACHINE GROUNDING.
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 Ultra 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 Ultra Advantage Servo Roll Feed is fully protected by line circuit breakers.
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

1.3 PLS ENCODER INSTALLATION (OPTIONAL)
The PLS encoder must be mounted on the press so its shaft is coupled or belted to the crankshaft with one to one (1:1) ratio. It is strongly recommended to use plastic chain or timing belt and plastic or aluminum sprockets on the encoder shaft.
When all required electrical connections are made, power up the feed control and bring up the Status screen:
T o o l # 1 Po s: 1 82 M a nu al Mo de 3 0 / Co nt .R u n P r e s s a M od e Ke y
Inch the press and watch the press position reading on the status screen. Verify that as the press is moving, the press position reading is changing in ascending order. If it is changing in descending order, then power down the feed control and swap the following wires:
Servo drive connector CN1B, pin 2 - orange wire;
Servo drive connector CN1B, pin 3 – red wire.
Power up the feed control and verify that the press reading is now changing in ascending order as the press moving.
NOTE:
CN1A and CN1B signal connectors on the Ultra5000 drive are spring-clamp connectors. A rectangle hole next to each wire hole is used to unclamp the connection by inserting the miniature screwdriver provided with the servo feed control.
