START-UP AND INTRODUCTION
Rapid-Air Start-Up Section (100C & D Series Servo)
Congratulations on purchasing a Rapid-Air Servo. Not only did you receive a complete servo unit but also telephone support by one of our engineering staff to guide you on using the new servo to its maximum capability.
In order to maximize your learning time and trouble shoot any interface problems, we would like
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 unchallenged combination in the press industry.
The compact mechanical package, direct coupled with a brushless servo drive motor, offers response and feed 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.
to request that the following items be complete before calling us.
1. Servo unit should be completely installed and aligned to a die on the press.
2. 120 vac electrical wiring should be in place and unit turned on.
3. All interface switches should
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
be wired and tested.
4. Air if needed should be connected and ready to be used.
5. All servo interface questions should first be directed to your distributor, then to Rapid-Air. Please call 815-397-2578 and ask to have these questions directed to the proper personnel.
at a slow rate. He can select jog to length or jog continuous to aid him in the threading up of material.
The precision mechanical roll feed unit has been designed for compact­ness, ease of setup and installation. A 120 VAC receptacle is all that is required of the customer. Two cables with twist lock plugs are supplied with the control and need only be connected to the proper locations on the motor. 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 SET-UP
Installation and Mechanical Set-Up of Servo Feed
The shipping container should contain:
1 Mechanical Servo Feed: –Standard 1 Console Complete: –Standard 1 Cascade Assembly: –Optional (100 Series) 1 Servo Mounting Bracket: –Optional 1 Guide Support Assembly: –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.
SERVO BOLT QUANTITY Series 100 All 3/8-16 4
The servo mounting bolts should not penetrate into the servo body by more than .625”.
Installation and Mechanical Set-Up 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 this 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 this bracket.
The unit is now assembled and the next step will be to attach the electrical and air, if used, 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.

ROll RElEASE SET-UP AND CAblING
Mechanical Roll Release Set-Up
All the 100 feeds have an optional mechanical pilot release. If the mechanical pilot release is used, (we recommend this for press speeds faster than 250 SPM) then a bracket has to be manufactured 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.
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 the roller pressure spring force.
OPTIONAL MANUAL PILOT RELEASE
The optional manual pilot release should be ordered at the time of purchase but can be added at a later date. Rapid-Air would like to perform the installation if at all possible.
OPTIONAL ELECTRIC PILOT RELEASE
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
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.
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.
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 and lightly 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 FEED wITh PRESS
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 or 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 them commands 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 input and wire per print. This input is brought down to a terminal strip for your convenience. The feed input number is (J52)TB1-2) and the pilot input number is (J52)TB1-4).
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 wRITE UP
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, turn on the on-off switch. The button should illuminate to indicate that there is power to the system.
The drive performs an initiate 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; if 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 you are using air, check that the main air is at least 80 PSI. Open and close the feed 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
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 hand
feed the material into the servo unit until it protrudes out of the feed rolls and starts into the guide on the press, 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
Servo Interfacing Explanation
A. TAUT STOCK INPUT (J52)TB1-6)
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 automatic 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. 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 before the servo can function 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 referance 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.
C. ENABLE OUPUT (J52)TB2-15) This output must be tied to a solid
state relay to interface 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.
END OF FEED OUTPUT
D.
(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 menu display on, 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.
E. 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 output to go low.
STANDARD PROGRAM -
F.
DATA INSTRUMENTS INTERFACE (J52)TB1-14)
With the jumper in place, the standard program is active. Remove the jumper, recycle power and the Data Instruments program is active. Only the manual mode will work with the keys at this time.
G. 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 into 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.

RESET PARAmETERS
Reset Job Parameters
The reset job parameters routing should be used with special caution. We incorporated it as a user function for two reasons.
The first reason is if a problem caused the displayed parameters to be garbled because of a program glitch, then by resetting the job parameters the problem could be cleared.
The second reason is if there were a number of different jobs in memory that were no longer required, then by resetting the job parameters, all the job numbers would be reset to their default values, which includes putting all zeros in the feed length and strokes per minute area of the program.
CAUTION!! CAUTION!! CAUTION!!
Keep a hard copy record of program numbers and data associated with them for reference if needed. If this function is used in a way other than what it was designed for then all previous data is lost and cannot be recovered.
To enter this function, turn off the program by depressing the master stop button. Turn on the program again and push and hold the “clear entry” key, once the program has started the following screen will be displayed.
**DEFAULT VALUE SETUP PRESS F1 TO RESET TO DEFAULT VALUES, PRESS F4 TO IGNORE CHANGES
**Once F1 has been pressed then all data that had been entered will be reset.
PROGRAM NUMBER DISPLAY
Each servo unit that is shipped has a program number assigned to it. If a problem occurs and cannot be solved by reloading the program then you will be asked the program number associated with this servo. To view the program number, press and hold the “back space” key during the power up sequence. The program number will be displayed for about 30 seconds. Please find and write down the program number in case it is needed in the future.

ENTER jOb ExAmPlE
Servo
To help you to enter a job from the keypad, let’s create an example. We will use a feed length of three inches and want to run at 100 strokes per minute. We have a pilot pin on the die, so pilots will have to be used. The max feed arc will be 180 degrees. The main menu is currently displayed. First we select the job number and we will use job #1.
1. Press F1 to select the job number.
2. Enter job number “01” – press the F4 key when finished.
3. The job number screen shows two choices:
A. F1 = program parameters. This choice is used if a job has al ready been programmed and you would like to adjust the parameters that were preset for the job. B. F2 = feed-advisor-calc. This should be used when entering a new job number. The two main inputs are the feed length and strokes per minute. The third input is to enter a “1” or a “0”
for pilots. We will put in a “1” for “yes for pilots”. The fourth input is the feed arc. This is preprogrammed as 180 degrees and need not be changed to set up a job unless specific move parameters in relation to press stroke position is required. To move around in this screen, press the “enter” key in the lower right corner of the key pad. Once the feed length and strokes per minute are entered, then the F4 key to exit the screen. The program now calculates the accel/decel and speed for the parameters entered. At this time the “F4 key” review parameter should be used to check to be sure that you entered the correct parameters.
4. Press “F2” to select the manual mode.
A. Press F1 to select the “inch” or jog mode. This mode will move the material slowly forward or reverse to position the material at it’s proper location. F2 being
used for forward and F3 for reverse movement. Press F4 to leave the “inch” mode. B. Press F2 to select the “single feed” mode. At this time each press on the F1 key will rotate the rolls to move the material three inches, the feed length that was entered, at the same feed rate as the feed would move the material in the automatic mode. Press the F4 key {exit} to leave this screen.
5. Press “F3” to select automatic cycle. In this mode the servo can be run in the batch or continuous mode.
A. Press F1 to select the batch mode. In the batch mode, the servo will feed each time it is commanded until the batch count reaches “0”, then the automatic cycle drops out. B. Press F2 to select the continuous mode. In the continuous mode, the servo will feed each time it is commanded until the command stops or the operator presses the “F4” return key.
