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 IN SHIPMENT 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
IMPORTANT Before turning the system on for the first time, verify that installation has been completed according to the Installation manual and the main input voltage is 220 VAC, single phase.
The P/A Industries Ultra Advantage Servo Roll Feed is a state of the art AC Servo feed, which simplifies Operator adjustments to feed parameters. These Operator adjustments are entered into the control memory through the keypad. With the use of positional limit switches, the press signals the feeder when to begin moving the strip, when the feed pitch must be completed, when the press has completed its down stroke, and with optional pneumatic pilot release, when to open the rolls for piloting.
The mechanical simplicity, accuracy, and ease of use of the Ultra Advantage Servo Roll Feed will help to improve your quality and production for years to come.

2.3 SERVOMOTOR/DRIVE OPERATION
The introduction of servomotor technology to the press roll feed has pushed the limits of accuracy, adjustability, and performance to levels previously unattainable.
The following example is based on the Ultra Advantage Servo Roll Feed Standard, US model. The actual numbers for Heavy Duty or metric models are different.
Each revolution of the servomotor produces 8000 encoder pulses. Every 10.24 revolutions of the servo motor shaft produce 1 revolution of the feed rollers. The circumference of the lower roll is approximately 11.138 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

.
ULTRA ADVANTAGE SERVO ROLL FEED 2/09/2002
Example: If a feed pitch/length of 11.138 inches is entered into the feeder, this will result in exactly one revolution of the feed rolls. The motor will accelerate and turn 10.24 turns. This will produce (10.24 x 8000 = 81,920) pulses of the encoder. The feeder will decelerate and stop, when 81,920 pulses are detected. The feeder is now in position. The result is an accurately positioned strip exactly 11.138 inches from its starting point. This entire process happens in milliseconds.

5 OPERATING THE ULTRA ADVANTAGE SERVO FEED
5.1 PROGRAMMING
OPERATOR screens are only screens that are Operator editable. These screens display Length, Count, Length Adjustment, Speed, Accel, Decel and Dwell. Length and Count can be changed only when cycling is stopped,
although Length can be adjusted by using the LENGTH ADJUSTMENT command even while the feed is running.
Access to the SET UP parameters can be locked by “Programming Locked/Ulocked” keyswitch.
5.2 PRIORITY MODE
The Ultra Advantage Servo Roll Feed has two modes of automatic cycle starting. The choice can be made between “Press – Before – Feed” (“PBF”) and “Feed – Before – Press” (“FBP”) operating mode.
When “PBF” mode is selected and the Cycle Start button is pressed on the control panel, the feeder causes the “Auto” and “Permit Press” relays to turn on thus enabling the start of continuous cycling on the press.
When “FBP” is selected and Cycle Start button is pressed on the feed control, the material/strip will be fed forward before the press is started. The Operator may verify that the strip is in position before starting the press.
The Ultra Advantage Servo Roll Feed will now follow the press until it is stopped by the Operator, counter, emergency stop, or feed error.
5.3 “JTL” (JOG TO LENGTH) MODE
“JTL” mode is used primarily during the threading of the strip through the die. This mode allows the Jog – To – “Feed Length” operations to be performed. While in the “JTL” mode, the strip may be moved using the remote Jog Pendant.
If the “Jog Forward” is stopped before the “Feed Length” is reached, then either the “Jog Forward” or the “Jog Reverse” Operator buttons will work. The “Jog Reverse” will not allow the strip to go backwards beyond the initial “Feed Length” starting point.
10
ULTRA ADVANTAGE SERVO ROLL FEED 2/09/2002
The “Jog Forward” Operator button will function until the end of the “Feed Length” is reached. During “JTL” mode, the bottom line on the display will show “Waiting for Jog”. When the “Feed Length” is reached, the jog buttons become inactive and the message on display will show “Waiting for Press”. The jog buttons will not become active again until after the press has made a cycle.
5.4 “AUTO / MANUAL” MODE
“Auto” Mode is used for production running of the UltraAdvantage Servo Roll Feed. When “Manual” mode is selected via the 2-position selector switch, the control can be put in “Auto” mode by pressing Cycle Start button.
During “Manual” mode, the feeder can be jogged infinitely in either direction. After the Cycle Start button is pressed, the jog buttons are inactive, and the feeding of the strip follows the cam signals from the press.
During “Auto” mode, the control keeps check on synchronization of the feeder and the press. If the feeder does not complete the index within the feed cam window, the message “SYNC FAULT” displays.
The Ultra Advantage Servo Roll Feed has 2 modes of automatic cycling. The feeder can operate with Single Stroke or Continuous modes. The mode is selected through an input to the feed controller. The Press single stroke/continuous mode switch should be interfaced to that input for proper operation. During single stroke mode operation, the “Permit Press” relay is activated upon the completion of each feed index.
The “Permit Press” relay remains activated until the reset cam signal turns on, or for the duration of the Dwell, if the Dwell parameter is programmed. The “Permit Press” relay may be used to signal the press when to initiate the single stroke cycle. The automatic cycling of the press and feeder will continue until the batch is completed, or the cycle is stopped by the Operator, or an error occurs.
During “Continuous Press” mode, the “Permit Press” relay turns on at the beginning of the indexing.
The “Permit Press” relay remains activated until the automatic cycling is stopped by either “Cycle Stop” button, “Batch Complete” internal command, “Sync Fault” or any other drive related error. Under “Cycle Stop” or “Batch Complete” stopping, the output will turn off at the beginning of the Feed Cam Signal. This should allow the press to stop near the top of the stroke. Under “Sync Fault” or other drive fault conditions, the “Permit Press” relay will turn off immediately upon detection of the error.
NOTE: The following speed performance charts represent theoretical calculations based on parameter values most commonly used. Higher performance for specific applications can be reached by custom tuning the control.

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-operation guards and devices. No specific references have been made to which paragraph of OSHA 1910.211, 1910.212, 1910.217 or any other applicable sections 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 selection of guards 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.
