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 110 VAC, single phase.
The P/A Industries Ultra Edge 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 Edge Servo Roll Feed will help to improve your
quality and production for years to come.
2 THEORY OF OPERATION
2.1 MECHANICAL ASSEMBLY
Mechanical assembly consists of:
1) Adjustment/Mounting bracket
2) Feeder
3) Servomotor
4) Mechanical pilot release actuator (optional)
5) PLS – Programmable Limit Switch (not available with SFI models)
2.2 ELECTRICAL CONTROL ENCLOSURE ASSEMBLY
Electrical control enclosure consists of:
1) Control switches/buttons/relays
2) Power supply, 24 VDC/5 VDC
3) Servo drive
4) Data entry terminal Cabling
5) Jog Pendant

Locks access to programming.
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 Edge Servo Roll Feed Standard, US (SRF-125, 200, 300, 400, 500,
600) models. The actual numbers for SRF-100 or metric models are different.
Each revolution of the servomotor produces 1048576 encoder pulses. Every 2.909 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.

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 2.909 turns. This will produce (2.909 x 1048576 = 3050307) pulses
of the encoder. The feeder will decelerate and stop, when 3050307 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.
2 PROGRAMMING THE ULTRA EDGE SERVO ROLL FEED SYSTEM OVERVIEW
NOTE: Before attempting any programming, make sure that the “PROGRAMMING LOCKED /
UNLOCKED” key switch is in the “Unlocked” position.
NOTE: After power shutdown, WAIT for 5 seconds before powering up the Feed.
Press the green Power On push-button. The button will illuminate and the OPERATOR terminal display will be
visible.
Wait for the IN POSITION light to illuminate.
Press any key to begin.
