INTRODUCTION
The Rapid-Air servo feed carries with it the quality and reliability you have grown to expect from a Rapid-Air product. The motion control system is a programmable industrial computer and this advanced technology combined with a highly engineered precision roll feed, is an unchallanged combination in the press industry.
The compact mechanical package, direct coupled with a brushless servo drive motor, offers response and feed speed accuracy unparalleled in any other powered roll feed. Operator interface is so simplified, a typical setup person can have the servo feed programmed and running in a matter of minutes. A step by step prompt on the four line 80 character display asks simple questions of the operator. Entry of feed length, strokes per minute, % maximum speed and pilot are all that is required for a new setup. Routine jobs can be stored, recalled, changed and saved or run with a simple 2 digit job number entry. Up to 99 jobs may be stored and recalled at will.
Operator programmed feed length, up to 999.999 inches and % max speed selection along with full jog features, allow the operator to thread the material and inch it into position. The inch feature enables the operator to jog the servo feed forward or reverse at a slow rate. The operator can select jog to length or jog continuous to aid in threading up material.
The precision mechanical roll feed unit has been designed for compactness, ease of setup and installation. A 230 volt, 3 phase supply and an air line are all that is required of the customer. Two cables with twist lock plugs and one or two cables for the air valve control are supplied with the control and need only be connected to the proper locations. The electrical controls are housed in a small cabinet which should be mounted close to the press working area. The operator keypad and display are mounted on top of the control area

INSTALLATION AND MECHANICAL SETUP OF SERVO FEED
The shipping container should contain: 1 Mechanical Servo Feed -Standard 1 Console Complete -Standard 1 Cascade Assembly -Optional (100 Series) (Standard 200-300 Series) 1 Servo Mounting Bracket -Optional 1 Guide Support Assy. -Optional
If a mounting bracket was purchased then it should be installed at this time. There are mounting bracket prints in the back of the manual for hole location dimensions and a bracket mounting instruction section can be found later in this section.
If a mounting bracket was not purchased then the feed should be positioned with the centerline of the drive roller in line with the centerline of the die entrance and at the proper pass line height to the die. Aligning the feed to the die (Parallelism) is very important to the accuracy of the feed. Drag due to misalignment can cause short feeds and servo faults.
If the feed is positioned as such that the material has to move unsupported from the exit side of the feed to the die and the material being moved is allowed to droop or buckle during a move, a short feed can occur. A guide should then be built between the feed and the die to solve this problem. The following chart lists the servo size with the proper bolt size.

The servo mounting bolts should not penetrate into the servo body by more than .625".

INSTALLATION AND MECHANICAL SETUP OF MOUNTING BRACKET
The cast mounting bracket is available for mounting the servo feed directly to the bolster plate of the press. There are several sets of mounting holes in the bracket to afford the setup person an efficient means of mounting the bracket. Mounting holes are located on the top and front for securing the bracket firmly. It is very important that the servo bracket and the servo feed be secured and not allowed to float or vibrate.
Note: It is very important that the end of the bolster plate where the servo feed is to be mounted, be perpendicular to the top surface of the bolster plate within +-.005 to assure the servo feed will be aligned for proper feeding.
Align the servo feed bracket with the center line of the bolster plate and transfer the mounting holes on the top face. There are two 1/2” holes on the smaller bracket and 3 1/2” holes on the large bracket.
Once the bracket has been aligned and secured to the bolster plate, the servo feed can now be put in place. The slotted holes in the mounting bracket allow for accurate alignment of the servo feed in the x-y axis. There is an elevating screw to position the servo feed to the proper tooling pass line height.
When the servo feed has been aligned and mounted to the bracket, loosen the elevator locking screws and position the servo to match the tooling pass line height. This is accomplished by turning the adjusting screw provided. When the servo is correctly positioned, tighten the elevator locking screws to prevent the unit from moving. There are 2 locking screws on the small bracket and 3 locking screws on the large bracket.
The unit is now assembled and the next step will be to attach the electrical and air to the servo feed unit.
Material alignment is critical. The servo feed rolls are so precise that they will move the material in whatever direction that they are presented to the die. The feed and die must be in line and square to one another. The servo feed does not have the power of a press driven roll feed so the feed will fault out if misaligned. This is a good warning and if corrected could result in better tool life.

MECHANICAL ROLL RELEASE SETUP
All Rapid-Air feeds are set up to add a mechanical pilot release. If the mechanical pilot release is used, and we recommend this for press speeds faster than 250 SPM, then a bracket must be fabricated and attached to the press ram to actuate the pilot release mechanism.
(Note: The roll release height adjustment screw should be backed off all the way to prevent jamming when using the mechanical release.
The bracket should be made adjustable for tuning to the press position in which the roll release should occur. Some attention should be given to the bracket stroke length so that the release mechanism is not jammed into the feed during the press stroke.
The 100 series pilot release actuator has a 1” stroke to full open with an additional .750” overtravel before bottoming out.
The series 200 and series 300 pilot release actuator has a 2” stroke to full open with an additional .750” overtravel before bottoming out.
We do not offer any manufactured bracket to assist you because there are as many combinations for stroke and clearance as there are presses manufactured today.
We do, however, ask that the bracket be designed to withstand considerable resistance as the mechanism has to defeat or overcome the incoming air pressure or roller pressure spring force depending on which servo unit you purchased.
ELECTRIC PILOT RELEASE If an electric pilot release is used and the servo is a series 200 or series 300 then a switch from the press has to be wired into the control box to control when the release has to take place. If a series 100 was purchased then an optional pneumatic pilot release has to be purchased.
OPTIONAL PILOT RELEASE #10900449 (100 series) The optional pilot release package consists of a valve, fitting, relay and solenoid cable. A switch signal from the press has to be wired to the control panel and an air line has to be connected to the valve from the main shop air. The relay and solenoid cable will have to be mounted and wired in the electric cabinet if it is to be used with the program.

ELECTRICAL CABLES AND AIR LINE
230 VAC INPUT The required in put voltage to the control is 230 Vac, 3 Ph, 60 Hz. The amperage needed is 6 amps for 752 control and 10 amps for the 753 control. If unsure of the amperage needed, the name plate on the side of the Pacific Scientific drive will give the number of the control or check the disconnect fuses for the correct fuse size.
460 VAC INPUT If you plant has only 460 Vac power then a step down transformer is needed in order to run the servo feed. If you purchased the transformer from Rapid-Air then all that is needed is to connect and wire the 460 volt line to the transformer. If you did not purchase a transformer from Rapid-Air then a transformer, 3 KVA for the 100S and 200S servos and 6KVA for the 300S servos, 460/230 VAC 3PH, 60HZ step down transformer is needed before proceeding with the electrical portion of the installation.
The electrical control enclosure is shipped completely ready to be connected to the mechanical feed. Connected to the bottom of the enclosure are (2) cables with keyed screw type connectors for connection to the motor and if the series 200 or 300 was purchased, (1 or 2) push on connectors for connection to the air valves for solenoid actuation of the pilot release and or anti-backup valve.
Position the electrical enclosure at a convenient location near the mechanical feed and attach the cables. The motor cables are easily identifiable by the amount of pins in the plugs. The solenoid cables if any can now be attached and checked for proper location when the feed is up and running.
An air line must be connected from the shop air to the air inlet of the servo feed. The air should be at least 80 PSI continuous and should be dry filtered andlightly lubricated for the best operation of the servo feed. The air inlet on the servo feed is a 3/8-18 NPT pipe tap. The minimum air line size requirement is 1/2”ID hose. - (2 CFM)

INTERFACING SERVO FEED WITH A PRESS
The Servo Drive unit is a slave to the press therefore it needs a command from the press to operate in the automatic mode.
The command is in the form of a normally open contact from a limit switch, cam switch or an electronic feed interface device that can be programmed.
The contact should be commanded or activated at 270 degrees of the press stroke or when the tooling is clear of the material and released and turned off at around 350 degrees of the press stroke. The significance of the release position is to insure that the feed switch is released with the press top stopped. Once the program senses a closure of the feed input, it will command a move and will complete the move regardless of the switch position.
The air operated pilot release also has to have a signal input to operate. The pilot signal should be set to turn on when the point of the pilot is entering the hole. This signal then commands the air roll release to raise and release the material, letting the pin pull the material forward into position. The release should be then commanded to turn off at approximately 180 degrees, letting the rollers return to a holding position for the next move.
The roll release stop adjustment screw is located at the entrance of the feed. (See drawing for your servo) The screw is used to limit the travel of the roller during release. Adjustment may be necessary if using air pilot release at a somewhat high speed with the pilot release deactivating and feed switch activating at a close proximity with each other in degrees of press stroke. To adjust, insert material into the feed, lower rolls, adjust screw, using 3/16 hex wrench, to full in. Release rolls and adjust screw so the material is free to be pulled in by the pilot pin. The adjustment is now complete. (NOTE: This adjustment does limit the manual roll release travel. If this causes a problem back off the adjustment a little.)
The schematic in the back of this manual points out the switch or contact connections for wiring the interface. Locate the feed and pilot signal input and wire per print. The feed input number is (J52)TBI-2) and the pilot input number is (J52)TBI-4).
This completes the initial setup of the servo feed to the press or other device. The servo is now ready to run as intended.
If more complete interfacing is needed, please refer to the section (interfacing ) in this manual for an explanation of inputs and ouputs available.

PRETEST FOR SERVO FEED AND PRESS WITHOUT MATERIAL Now that your servo feed unit has been mounted and the cables have been attached, you can proceed with testing the unit. The first step is to turn on the main disconnect switch on the electrical enclosure. Next, at the operator’s console, pull the power on­off button to the on position. The button should illuminate to indicate that there is power to the system.
The Pacific Scientific drive preforms an initial sequence to check it’s internal program. At this time the display should show the Rapid-Air screen for 5 seconds before starting the main setup program. If you are comfortable with programming a job then continue, it not, please refer to the “Programming Procedure” located in this manual.
Follow the programming sequence for the operators terminal to input parameters into job storage. Your servo feed has been fully tested before it was shipped to your facility and this procedure is merely a test to insure that all functions are still functional and the cables are properly seated.
Once you have programmed the required parameters, select the manual mode of operation. If the option of air regulated upper feed roll was purchased, check that the main air is at least 80 psi and check that the roll pressure gage is functional by adjusting the pressure up and down, This is accomplished by turning the pressure adjusting knob. If you did not purchase the air regulated roll option then check that you have enough tension on the material to avoid slipping during feeding. Open and close the feed and anti-backup rolls electrically and or manually. Visually inspect that the rolls open and close as you press the appropriate keys on the keypad or when using the manual levers.
Select the “inch” function (F2 on keypad) on the manual mode screen. Visually check that the rolls rotate both forward and reverse with the corresponding key. The speed is preset to creep the rolls at a slow speed for manual positioning of the material.
CAUTION: Do not attempt to place your fingers or any foreign material into the rolls. Injury to the operator or damage to the servo rolls could result.
After you have verified that the rolls and air logic are operational, you can experiment with the single cycle moves. The procedure is outlined in the programming section of this manual.
Now, you can cycle the press and watch the rolls to verify that the signal from the press window switch signal is functional and actuating at the proper time.
After all the checks have been made and you feel comfortable with the programming of the servo controller, place the servo in automatic mode. Now cycle the press in either the inch, single stroke or continous run, the servo feed should react upon the closure of the press window and signal and simulate a feed progression of material.

LOADING MATERIAL INTO THE SERVO FEED
Upon the satisfactory completion of all the tests, you should be ready to load a strip of material into the servo feed.
Step number one is to select the manual mode of operation on the operators console. Then choose “Operate Rolls”. This will allow you to open the feed rolls and anti­backup rolls to accept the material. You could also open the rolls manually by lifting the lever mounted on the side of the servo feed. Position the leading edge of the material with the center of the material near the center of the entry rolls. Adjust the edge guides on the cascade rolls to the proper width setting. Open the feed rolls and or anti-backup rolls. Hand feed the material into the servo unit until it protrudes out of the feed rolls and starts into the guide on the press. Close the anti-backup rolls (if purchased) to capture the material, then close the feed rolls.
Check the roller force pressure to be sure that there is enough pressure to prevent slippage but not too much to induce camber into the material. The pressure setting is the amount of force necessary to move the material into the press at the speed and feed programmed. You may find it necessary to readjust the force as you finalize the setup procedure. The amount of force needed will vary depending on the width and type of material being fed. Make a note of the final setting to aid in the setup of the servo feed the next time the same material is run.
You are now ready to begin testing the complete system under power. To check the progression, cycle the press in the single cycle mode with the servo feed in the automatic mode. If the progression is correct, no further adjustments are necessary. If the progression is either short or long, go to the troubleshooting chart and perform the sequences described there for inaccurate feeding, once the feed progression has been accuratelly set and the repeatability is satisfactory, you are ready for full automatic mode.

SERVO INTERFACING EXPLANATION
A. TAUT STOCK INPUT (J52)TBI-6) This is a normally open contact from a switch or device that monitors the loop of material prior to the servo feed. When the material reaches a point that it trips the switch, a taut stock has been reached. This input, when received, immediately drops the automatic which stops the feed in progress. The material should be repositioned in the die before restarting the automtaic sequence, as the progression was lost when the taut stock occurred.
This input also could be used as a “No Stock” switch that would monitor whether or not there is material available to feed.
B. ANTI-BACKUP INPUT (J52)TBI-8) Whether the anti-backup rolls where purchased with the unit or came on the unit standard, they can be activated to raise in the automatic cycle. The anti-backup rolls, by design, keep the material from sliding back during the pilot operation. They can become a hinderance if the material tend to walk to one side or the other during the feed cycle.
The anti-backup switch can be used as a solution. If the material walking problem is being experienced then a switch or a cam switch with a normally open contact can be wired in from the press. Usually this switch is activated when the press is at 180 degrees or when the die is closed to be sure that the material is being held in position. The rolls will raise for the amount of degrees that the switch is activated, letting the material reposition itself in line with the die. It is crucial that this switch is not activated for too long a time as when the die releases the material, the material will slide back which will cause a misfeed. This feature has to be used in conjunction with the main rolls being raised or it will not give the desired results as one of the rolls will be holding the material from moving.
C. ENABLE INPUT (J4-Pin 5 & 6)) The enable input is shipped from the factory, jumpered, so that the Pac-Sci unit is ready to work after the initialization procedure is complete.
If it is desired that the servo controls are not functional until other equipment or safety source is activated then a normally open contact can be interfaced to this input. If at any time during the feed cycle the input changes state then the feed will stop at this position. If feeding stock, the reference will be lost and the stock will have to be manually repositioned to the correct location. The automatic cycle will be dropped and have to be restarted.
12
D. ENABLE OUPUT (J52)TB2-15) This output must be tied to a solid state relay to interfact to the ouside world. The solid state relay must have a D.C. coil and should have a rating of 3-30 VDC. The Rapid-Air #69100165 is recommended for this application. This output is high whenever the enabled input is activated.
E. END OF FEED OUTPUT (J52)TB2-13) This output must be tied to a solid state relay to interface to the outside world. The solid state relay must have a D.C. coil and should have a rating of 3-30 VDC. The Rapid-Air #69100165 is recommended for this application. This output goes high at the end of every feed and stays high for programmed amount of time before going low. To program the time, with the main screen menu displayed, push the period on the keypad - follow the instructions and enter the time in milli-seconds. The time entered will add to the total feed cycle time and if programmed to last longer than the time from the actual end of feed and the actual tripping of the feed switch then the program will not see the feed switch being tripped. You will then get two hits per feed.
F. AUTOMATIC OUTPUT (J52)TB2-11 This output must be tied to a solid state relay to interface to the outside world. The solid state relay must have a D.C. coil and should have a rating of 3-30 VDC. The Rapid-Air #69100165 is recommended for this application. This output goes high whenever automatic is selected on the program panel. Any faults will cause the automatic ouput to go low.
G. STANDARD PROGRAM- DATA INSTRUMENTS INTERFACE (J52)TB1-14) With the jumper in place, the standard program is active. Remove jumper, recycle power and the Data Instruments program is active. Only the manual mode will work with the keys at this time.
H. KEYPAD AND DISPLAY INTERFACE (RS232 PORT) The keypad/display is the interface between the operator and the resident program. The Pacific Scientific drive is purchased with a great many capabilities, none of which can be used unless a program is written to utilize these capabilities. Rapid-Air put a great deal of time making a program that is user friendly and yet gets the job done efficiently. We took all the questions and constructive criticism and came up with a program that would cover all the applications, yet be easy to interface and program by a customer.
If an operator reads the programming procedure in this manual and then reads the screen parameters listed as they are displayed and acts on them by inputting data as needed, the servo can be up and running in a very short time.
1. Select a job number.
2. Input or review parameter for that job number.
3. Thread up material in manual mode.
4. If properly interfaced, go into automatic mode.
