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.

2.3 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.

2.4 TOOL STORAGE OPERATION

The tool storage feature allows for storing of parameters that are different from tool to tool. It takes just a few seconds to activate feeding parameters associated with a certain tool number. Maximum 200 tools can be stored. Tools are organized by Tool number, which is user definable and can contain up to 7 digits.

Each tool consists of the following parameters: -Length;

-Batch Count;

-Speed;

-Dwell;

-Accel;

-Decel;

-Feed Cam “On”;

-Feed Cam “Off”;

-Reset Cam “On”;

-Reset Cam “Off”;

-Pilot Release Cam “On”;

-Pilot Release Cam “Off”;

-Aux1. Cam “On”;

-Aux1. Cam “Off”;

-Aux2. Cam “On”;

-Aux2. Cam “Off”;

-Aux3. Cam “On”;

-Aux3. Cam “Off”;

NOTE: Cam settings are available only with PLS version of software.

Consider the tool storage as a part of the servo drive’s NVRAM memory that is dedicated to storing information of all the existing tools. In order to run a tool, it must be activated. Tool activation is an internal drive procedure of making a copy of the tool, and placing it in a different memory location. This copy, not the tool in the tool storage, is used to perform material feeding. “Tool #NNN is active” means only that the feed running parameters are copied from this tool.

A tool in the tool storage area and its copy, are edited independently, with the difference, that only two of the copy’s parameters are accessible – Length and Batch Count. These are accessible from the Operator screen. In order to edit the rest of the parameters of the tool, the tool in tool storage must be edited, and then, reactivated.

NOTE: Deleting an active tool from the tool storage causes deletion of its copy as well.

NOTE: An active tool remains active after power recycling.

2.5 PLS OPERATION (OPTIONAL)

The PLS, Programmable Limit Switch consists of an intelligent encoder and the cable that connects the encoder to the servo drive. The encoder is mounted on the press and its shaft is coupled or belted to the crankshaft with a one to one (1:1) ratio. On every power-up, the encoder turns into the intelligent mode (for approximately 10 msec) to read its actual position and store it in the servo drive.

The encoder then turns into the incremental mode, sending the count signals to the servo drive proportionally to the angle of the move (1024 counts per revolution). The servo drive software, having the start point position of the

5

ULTRA EDGE SERVO ROLL FEED

encoder shaft, constantly calculates (updates) its current position. The position of the press crankshaft is determined through the offset parameter, which is the position of the encoder shaft when the press is in its 0 degree position (TDC).

Thus, at every point of the stroke, the servo drive knows where the crankshaft is. The servo drive controls six cams simultaneously, turning them on and off accordingly to the cam settings.

Since the PLS encoder is connected directly to the servo drive, there is no need to wire connections for the Feed Cam and the Reset Cam outputs. These outputs are software type outputs.

The rest of the cam outputs are hardware type and require wiring of output relays to the desired mechanisms, such as a pilot release solenoid, parts blow-off, tool lubricator, etc. The cam settings (On/Off angles) are set through the operator terminal. They are part of the tool settings.

NOTE: All PLS outputs are active as soon as SRF power is turned on.

2.6 STRIP ENCODER-OPERATION (OPTIONAL)

The Strip Encoder assembly consists of:

a.300mm diameter knurled measuring wheel

b.10,000 pulses per revolution encoder

c.Air valve with manual actuator

d.Air cylinder slide

e.Magnetic sensor

The encoder measuring wheel is coupled to the encoder and both are mounted on the slide. The slide can be moved up and down by applying air pressure (80-100 PSI) to the air cylinder. The magnetic sensor is used to indicate the up/down position of the measuring wheel.

The encoder output results in 40,000 pulses (counts) per revolution for a final resolution of 3386 counts per inch of linear strip movement.

While the measuring wheel is in its up position, the servo roll feed acts as if there is no strip encoder attached to it, and all of the SETUP parameters associated with a strip encoder operation are inactive.

The Strip Encoder may be used to control or to check the position of the material strip.

The P/A Industries® servo roll feed with optional Strip Encoder comes standard with the ability to function in one of the two modes.

1. CONTROL MODE

In this mode the position control of the material motion is done through Strip Encoder feedback. The velocity control is based on data coming from both, Strip Encoder and Motor Mounted Encoder.

This mode provides relatively slower speed performance, due to the increase in computation of the velocity control algorithm.

2. CHECK MODE

In this mode the full control of the material motion (Acceleration, Deceleration, Speed and positioning) is done through the motor mounted encoder. When a move is complete, the Strip Encoder positioning control checks if the material is within the Length Check tolerance, if it is not, "Position Error" is displayed, and Auto mode is turned off.
