New Features

(Ref.0204in)

Version 5.2

(March 1995)

1. P621(4). DIVIDING FACTOR FOR ELECTRONIC HANDWHEEL FEEDBACK SIGNALS
Machine parameter P621(4) is used with P602(4) and P621(5) which indicate the multiplying factor for the electronic handwheel feedback signals for the 1st and 2nd axis respectively. Machine parameter P627(1) indicates whether all handwheel feedback signals are to be divided or not. P621(4)=0 They are not divided. P621(4)=1 All handwheel feedback signals are divided by two. Examples for the X axis so the CNC assumes 100 pulses/turn with 25, 50 and 100 line handwheels: 25 line Fagor handwheel: 50 line Fagor handwheel: 100 line Fagor handwheel: P602(4)=0 and P621(4)=0 P602(4)=1 and P621(4)=0 P602(4)=1 and P621(4)=x 4 / 1 = 100 lines 50 x 2 / 1 = 100 lines 100 x 2 / 2 = 100 lines

Version 5.6

1. JOG WITH MASTER HANDWHEEL

(June 1996)

With this feature it is possible to jog the machine with the Master Handwheel once the path has been defined. Requirements: The control of the "Jog with Master Handwheel" is carried out with the Second Handwheel. Therefore, the machine must have two electronic handwheels and none mechanical. Parameter setting: Machine parameter "P622(6)" indicates whether this feature is being used or not. P622(6) = 0 "Jog with Master handwheel"is not available. P622(6) = 1 "Jog with Master handwheel"is available. As stated above, the control of the "Jog with Master Handwheel" is carried out with the Second Handwheel. Therefore, the machine must have two electronic handwheels and none mechanical. This means that: P621(7)=1 The machine does not use mechanical handwheels. P622(3)=0 It uses two electronic handwheels. P609(1)=0 The first handwheel is not a FAGOR 100P model. The Master handwheel is connected via connector "A4". It admits both sine-wave and square-wave differential signals. This implies setting the following machine parameters as follows: P621(6) Counting direction of the "Master Handwheel". P621(3) Feedback units of the "Master Handwheel". P621(1,2) Feedback resolution of the "Master Handwheel". P621(5) Feedback multiplying factor for the "Master Handwheel". Selection: a) CNC Models: 800TI and 800TGI. From the PLCI. Once all machine parameters have been set, PLCI output O39 must be used to enable or disable the "Jog with Master Handwheel" feature. Parameter P622(6) PLCI output O39 "Jog with Master Handwheel" P622(6) = 0 ----Feature not available P622(6) = 1 O39 = 0 Feature disabled P622(6) = 1 O39 = 1 Feature enabled b) CNC Models: 800T and 800TG. Using pin 11 of connector "I/O 1". Once all machine parameters have been set, the "Jog with Master Handwheel" input (pin 11 of I/O 1) must be used to enable or disable the "Jog with Master Handwheel" feature. Parameter P622(6) P622(6) = 0 P622(6) = 1 P622(6) = 1 Pin 11 I/O1 ----Pin 11 at 0Vdc Pin 11 at 24Vdc "Jog with Master Handwheel" Feature not available Feature disabled Feature enabled
Basic Operation. (P622(6)=1, O39=1) a) When the machine is stopped. Only the first handwheel is enabled, the second one (Master) is disabled. Therefore, only the X axis may be jogged with the handwheels. b) When the machine is running (CNC in Execution). The axes do not start moving until the Master Handwheel is turned. The axis feedrate depends on the turning speed of the Master Handwheel. If it stops, the axes also stop. If the Master Handwheel is turned in the opposite direction, the axes also invert their moving direction (Return Function for one block only). c) The "Jog with Master Handwheel" feature may be used with any type of execution, be it a cycle, an ISO-coded program, a Chamfer, etc. Usually, with the CNC in execution, the first handwheel is disabled, except for the semi-automatic mode of the automatic operations: "Taper Turning" and "Rounding". On both Semi-automatic operations, the Master Handwheel controls the feedrate of the tool path and the First Handwheel will move the X axis. "Jog with Master Handwheel" feature disabled. (P622(6)=1, O39=0 ) When this feature is disabled, PLC output O39 is set to "0" and the handwheels operate like until now (as on previous versions).

4. MANUAL SPINDLE GEAR CHANGERS
Operation on previous versions To manually change the spindle speed range (gear), machine parameter "P601(1)" had to be set to "0". When the new selected spindle speed "S" involved a gear change, the CNC displayed a message indicating which range had to be selected. The operator had to proceed as follows: 1st- Stop the spindle 2nd- Manually change gears 3rd- Restore spindle rotation 4th- Press [ENTER] The CNC resumed program execution. Operation on current and future versions To manually change the spindle speed range (gear), machine parameter "P601(1)" must set to "0". When the new selected spindle speed "S" involves a gear change, the CNC displays a message indicating which range has to be selected. The operator must proceed as follows: 1st- Manually change gears 2nd- Press [ENTER] The CNC restores spindle rotation and resumes program execution.
VARIABLE BACKLASH COMPENSA TION
Until now, the 800T CNC allowed for a single leadscrew backlash compensation. From now on, it is also possible to compensate for motion-reversal backlash depending on the particular backlash areas of the axes.
Requirements: The leadscrew error compensation tables are now used for leadscrew error compensation and for this "Variable Backlash Compensation" (at the same time). Parameter setting: Machine parameters "P622(7)" and "P622(8)" indicate whether this feature is available or not. P622(7) = 0 Not available for the Z axis. P622(7) = 1 Available for the Z axis. P622(8) = 0 Not available for the X axis. P622(8) = 1 Available for the X axis. In order to use "Variable Backlash Compensation", regular leadscrew compensation must also be activated. P605(2) = 0 X axis Leadscrew error compensation (0= No, 1= Yes) P605(1) = 0 Z axis Leadscrew error compensation (0= No, 1= Yes) Operation: The first 15 points of the table are for the positive direction and the other 15 for the negative direction. When compensating for leadscrew error, the amount of backlash is the difference between both graphs.
When leadscrew error compensation is not to be used, all the values of one of the tables must be set to "0"; thus, the other graph will correspond to the leadscrew backlash.

Notes:

Both graphs must meet all the requirements of the leadscrew error compensation tables. One of these requirements states that the Machine Reference Zero (home) must be assigned an error of "0". If the leadscrew has some backlash at this Machine Reference Zero point, that amount of backlash must be allocated

Once the tool is "out of the way", the spindle may be started and stopped again by its corresponding keys at the Operator Panel. d) Once the tool inspection or replacement is completed, press [END]. The CNC will execute an M03 or M04 function to start the spindle in the direction it was turning when the program was interrupted. The screen will display the following message: RETURN AXES OUT OF POSITION "Axes out of position" means that they are not at the position where the program was interrupted. e) Jog the axes to the program interruption position by means the corresponding jog keys. The CNC will not allow to move them passed (overtravel) this position. When the axes are in position, the screen will display: RETURN AXES OUT OF POSITION NONE f) Press to resume the execution of program P99996.

4.3.1 CONSTANT SURFACE SPEED LIMIT
When working at constant surface speed, it may be interesting to limit the spindle speed (rpm). To do this, the CNC shows the MAX ???? value corresponding to the maximum speed the spindle may reach. To set this speed, press [S] Key in the value and press [ENTER] The entered value will appear to the right of MAX and, from then on, the spindle speed (rpm) will be limited to this value.
Section: CONSTANT SURFACE SPEED
4.4 SPINDLE SPEED RANGE CHANGE
With this CNC, the machine can have a gear box in order to adapt the speeds and torques of the spindle motor to the various machining requirements. When the new spindle speed "S" requires a range change, the CNC will act as follows: * * If the machine has an automatic range changer, the CNC will select the corresponding range. When the machine does not have an automatic range changer, the CNC interrupts the execution of the program and indicates to the operator which range corresponds to the selected "S" speed so he can change it.
4.4.1 MANUAL SPINDLE RANGE CHANGE
When not having an automatic range changer and the new selected spindle speed "S" requires a range change, the CNC acts as follows: 1.- Once the need for a range change has been detected, the CNC will show at the last line of the editing window, the range to be selected. 2.- After making the range change, press [ENTER]. 3.- The CNC will then consider the range change completed and it will output the analog voltage corresponding to the new spindle speed selected. If the new selected spindle speed "S" requires a range change and it is to be ignored, press [CLEAR] in step "2" instead of [ENTER]. The CNC will cancel the range change operation and it will recover the spindle speed set before.
4.4.2 AUTOMATIC SPINDLE RANGE CHANGE
When having an automatic range changer, the CNC will manage the electrical cabinet to perform that change, thus not requiring operator intervention.

Section: RANGE CHANGE

4.5 CLOCKWISE SPINDLE ROTATION
To turn the spindle clockwise once the spindle speed has been selected, press When the spindle is turning, a new speed may be selected or change the current speed by means of the following keys: Every time this key is pressed, the CNC increases the spindle speed by 5%. The maximum being 120% of the programmed speed. It must be borne in mind that the maximum speed is limited by the value assigned to the range currently selected. Every time this key is pressed, the CNC decreases the spindle speed by 5%. The minimum being 50% of the programmed speed.
4.6 COUNTER-CLOCKWISE SPINDLE ROTATION

Indicates the final diameter or final depth to be obtained with the grooving operation. Defines the grooving step. If programmed with a value of "0", the CNC will take the "N" value into account. Defines the number of grooving passes. This parameter will be taken into account when =0. If both the and "N" are programmed with a "0" value, the CNC will issue the corresponding error message.

Before starting to execute, the CNC will calculate the real pass along the Z axis required for the grooving operation. All the passes will be identical. The machining steps will be the following: 1.2.The spindle will start at the selected speed and turning direction. If the execution of the cycle has been programmed with another tool, the CNC will make a tool change by moving the axes to the tool change position if so required by the machine. The tool will approach the Begin point maintaining the selected safety distances along the X and Z axes. Every grooving pass is carried out as follows: a/ Position the cutter facing the area to be grooved. The first time it will be positioned at a "TW" (tool width) distance from the "BEGIN" point. The rest of the times, it will move the grooving pass. b/ Grooving of the section. If there is no finishing pass, % = 0, to the bottom of the groove. If there is finishing pass, it leaves the amount set by % for the finishing pass. c/ Dwell at the bottom. In order to achieve a good part finish, the cutter will stay at the bottom of the groove for another 2 spindle turns. d/ Withdrawal on X. 5.If set for a finishing pass, after the last grooving pass, the CNC will run a final finishing pass to the whole groove.

* Press [TOOL] and, after keying in the desired number, press [ENTER]. The CNC stores the new selected tool but it will maintain the previous one active. * Press [TOOL] and, after keying in the desired number, press The CNC selects the new tool and assumes it for the automatic operation being edited. It must be borne in mind that the CNC uses this tool for roughing and that it is possible to select another tool for the finishing pass.

PROFILE DEFINITION

When selecting the AUTOMATIC MODE (CYCLE), the CNC show the values corresponding to the profile points currently available; being possible to select new values if so desired.
The following data must also be defined: H Defines the amount of material to be removed from the original part. It is programmed in radius. - If programmed with a positive value, the CNC will perform roughing passes parallel to the programmed profile. - If programmed with a "0" value, the CNC will perform one single finishing pass (no roughing passes). - If programmed with a negative value, the roughing pass will be a turning or facing pass. Also, if a profile is defined with "valleys", the CNC will issue the corresponding error. Since there is no key to select it, do the following: * Select another data and then use the up and down arrow keys to select parameter "H".

When "K" is followed by a figure, it can be a value between 0 and 99.99 seconds whereas when followed by an arithmetic parameter (KP3) this parameter value may be between 0 and 655.35 seconds. The dwell is executed at the beginning of the block containing it. "G04" may also be programmed as "G4".
6.2 DISPLAY ERROR CODE (G30)
As soon as the CNC reads a block containing the "G30" code, interrupts the running program and displays the indicated error. Programming format: N4 G30 K2(0-99) N4 G30 K2
Block number Error programming code Error code number to be displayed
The error code may also be programmed by an arithmetic parameter between P0 and P255. For example: N4 G30 KP123. This code, in combination with G26, G27, G28 and G29, permits interrupting the program and detecting possible measuring errors, etc. A block containing "G30" cannot have any other information.
When wishing the CNC's own error code comments NOT to appear on the screen, the error code number to be displayed by "G30" must be greater than those used by the CNC. Remember that the operator may write comments in the program and the CNC will display them when executing the corresponding block.

6.3 UNCONDITIONAL JUMP / CALL (G25)
Function "G25" may be used to jump from one block to another within the same program. The block containing "G25" may not contain any other information. There are two programming formats. Format a) N4 G25 N4 N4 G25 N4 Block number Unconditional jump code Block number jumping to
When the CNC reads this block, the program "jumps" to the indicated block and continues its execution from there on. Example: N0 G00 X100 N5 Z50 N10 G25 N50 N15 X50 N20 Z70 N50 G01 X20
When reaching block N10, the CNC skips blocks N15 and N20 continuing from N50 to the end of the program. Format b) N4 G25 N4.4.2 N4 G25 N4.4.2 Block number Unconditional jump code Number of repetitions Number of the last block to be executed Number of the block jumping to When the CNC reads a block of this type, jumps to the block defined between "N" and the first period. Executes the program portion between this block and the one defined between the two periods as many times as indicated by the last figure. This last figure may be between 0 and 99. However, if an arithmetic parameter is used to define it, its value may be between 0 and 255. When writing only N4.4, the CNC will execute this program section only once (same as for: N4.4.1) Once the CNC has completed the last repetition of the section, it returns to the block following the one containing "G25 N4.4.2 "

6.5 SCALING FACTOR (G72)

By using functions "G72", it is possible to enlarge or reduce programmed parts. This way, it is possible to program several parts having the same shape but different sizes in a single program. "G72" must be programmed alone in the block. The programming format: N G72 K N4 G72 K2.4
Block number Scaling factor code Value of the scaling factor
Minimum value K0.0001 (Multiplied by 0.0001). Maximum value K99.9999 (Multiplied by 99.9999). After "G72", all the programmed coordinates will be multiplied by the indicated K value until another scaling factor is programmed or it is canceled. To cancel the scaling factor, just program another one with a "K1" value. It is also canceled when executing an M2, M30, RESET or EMERGENCY.
Section: SCALING FACTOR (G72)

6.6 PROBING (G75)

By means of this function, it is possible to use a touch probe connected to the CNC. The programming format is: N4 G75 X4.3 Z4.3 in millimeters. N4 G75 X3.4 Z3.4 in inches. The axes will move until the probe signal is received. Once it is received, the CNC will consider that the block has been executed (in position) and it will assume the current position of the axes (at the instant the probe signal was received) as their theoretical position. The probing feedrate cannot be overridden by the MFO switch and it will be set at 100% of the programmed value. If the axes reach the programmed position before the CNC receives the probe signal, the CNC will issue error 65. Once this block has been executed, the current position values of the axes may be assigned to arithmetic parameters. This, combined with the possibility to perform mathematic operations with the arithmetic parameters, permits editing special tool calibration and part measuring programs. Function "G75" implies functions "G01" and "G40" which means that once "G75" is executed, the CNC assumes "G01" (linear interpolation) and "G40" (cancelation of tool radius compensation).

TURNING CANNED CYCLE WITH CURVED SECTIONS (G84)
Format: N4 G84 P0=K P1=K P2=K P3=K P5=K P7=K P8=K P9=K P18=K P19=K Parameter meaning: P0: P1: P2: P3: P5: P7: P8: P9: P18: P19: X coordinate value of point A (radius or diameter). Z coordinate value of point A. X coordinate value of point B (radius or diameter). Z coordinate value of point B. Max. step. It must be greater than zero or error 3 will be issued. The real step calculated by the CNC will be smaller than or equal to the max. step. Finishing stock allowance on the X axis. It must be greater or equal to zero or error 3 will be issued. Finishing stock allowance along the Z axis. It must be greater or equal to zero or error 3 will be issued. Feedrate of the finishing pass. If it is zero there will be no finishing pass. If it is negative, error 3 will be issued. Distance I between the point A and the arcs center along the X axis. Although the X axis is programmed in diameter, the values of I are always programmed in radius. K distance between the point A and the arcs center along the Z axis.
Section: TURNING WITH CURVED SECTIONS (G84)
Programming example (in diameter): Starting point: "0" (X149 Z86). Profile points: "A" (X0 Z71), B(X120 Z11). Arc center: "C" (X160 Z91). N90 G00 X149 Z86... (Tool positioning at point "0") N100 G84 P0=K0 P1=K71 P2=K120 P3=K11 P5=K5 P7=K4 P8=K4 P9=K100 P18=K80 P19=K20 When programming this canned cycle, take into account the following aspects: 1. The distance between the starting point 0 and final point (B) along the Z axis must be equal or greater than P8. To avoid passes that are too thin or generating error 31 when operating with tool compensation, the value of this distance (from 0 to B) should be equal to P8+N P5, N being an entire number. 2. 3. The distance between the starting point 0 and the point (A), along the X axis, should be higher than P7. The machining conditions (feedrate, spindle rotation.) must be programmed before calling the cycle. The parameters can be programmed either in the cycle calling block or in previous blocks. This canned cycle does not alter the call parameters which may be used in later cycles. However, it does modify the values of parameters P70 through P99. The movements of the elemental work cycle (see drawing) are carried out as follows: At the programmed feedrate from point "1" to point "2" and from "2" to "3"; but in rapid from point "0" to point "1" and from "3" to "0". The exit conditions are G00 and G90. 4. 5. 6. If the position of the tool is not correct to execute the cycle, error 4 will be issued. If it is correct a prior horizontal turning will be carried out if necessary. If there is a finishing pass, the cycle will be completed on the tools starting position (0). If there is no finishing pass the cycle will end at point F. If the last movement prior to calling the canned cycle has been executed in G00, tool radius compensation (G41,G42) can be used. Otherwise error 35 will be issued.
