1.2.3 DENYING ACCESS TO THE EDITOR MODE VIA PLCI
Machine parameter"P627(7)" indicates whether this feature is available or not.
P627(7)=0This featureis not available.
P627(7)=1This featureis available.
When using this feature, access to the editor mode at the CNC depends on the status of PLCI output O26, as well as
on the current conditions (protected memory, number of the program to be locked).
O26=0Free access to the editor mode (it is protected by current conditions).
O26=1Denied access to the editor mode.
1.2.4 SPINDLE CONTROLLED VIA CNC OR VIA PLCI

P627(7)=0This featureis not available
P627(7)=1This featureis available
Setting the spindle analog output via PLCI
To do this, use the combination: M1956 - R156.
Register R156 sets the spindle analog output in units of 2.442 mV. (10 / 4095)
R156=00001111 11111111 (R1256=4095) = 10V.
R156=00011111 11111111 =-10V.
R156=00000000 00000001 (R1256=1) = 2.5mV.
R156=00010000 00000001 =-2.5mV.
In order for the CNC to assume the value allocated to register R156, one must activate mark M1956 as described
inthePLCIManual (section5.5.2. Writinginternal CNCvariables).
Spindle controlled either by the CNC or by the PLCI
The CNC may have two internal spindle analog outputs, that of the CNC itself and the one set by the PLCI.
Use PLCI output O27 to "tell" the CNC which one of them to output.
O27=0Spindle analog output set by the CNC itself.
O27=1Spindle analogoutputset by the PLCI (combination: M1956-R156).
1.3 READING INTERNAL CNC VARIABLES
From this version on, the PLCI and the PLC64 have access to more internal CNC information.
With the PLCI, there is no need to activate a mark to access this information. The CNC itself updates this information
at the beginning of each PLCI cycle scan.
With the PLC 64, the corresponding mark must be consulted every time a CNC variable is to be checked.
The CNC information now accessible is:
Real S in rpm (REG119 at the PLCI, M1919 at the PLC64)
Not to be mistaken with R112 which indicates the programmed Spindle speed (S).
Itisgiveninrpmandinhexadecimalformat.Example:S2487 R119=967
Number of the block in execution (REG120 at the PLCI, M1920 at the PLC64)
Itisgiveninhexadecimalformat.Example:N120 R120=78
Code of the last key pressed (B0-7 REG121 at the PLCI, Not available at the PLC64)
Not to be mistaken with register R118 which also indicates the code corresponding to the last key pressed,but-
-
When pressing a key, both registers have the same value; butthe data in R121 is only kept there for one cycle
scan whereasR118 keeps its value until another key is pressed.
When pressing the same key several times, (for example: 1111):
R121 will show code "1" four times (once per cycle scan).
R118 will always show the same value, thus not being able to tell whether the "1" key has been pressed once
ormoretimes.
The key codes are listed in the appendix of the PLCI manual.

2. RETRACE FUNCTION.
This feature is available on the following models:
CNC-8025M CNC-8025MG CNC-8025MS
CNC-8025MI CNC-8025MGI CNC-8025MSI
Machine parameter "P627(6)" indicates whether this feature is available or not.
P627(6)=0This featureis not available
P627(6)=1This featureis available
This function may be selected by the operator. To do this, activate:
OnmodelswithoutPLCI: pin 7 of connector A5.
OnmodelswithPLCI: PLCIoutputO47
Operation:
As the CNC executes motion blocks, it always stores the last 10 blocks already executed
Whenever it executes a block containing an M,S,T type function, the machining conditions change and the CNC
deletes those previously stored motion blocks.
When the retrace function is activated, the block currently in execution is interrupted and the retrace process
begins.
First to the starting point of the current block and, then, to that of the previously stored program blocks.
If all the stored blocks are executed, the CNC stops the machine until the retrace function is canceled.
When this function is canceled, the CNC interrupts the current movement (if any) and it executes all the retraced
blocks again. Once the interruption point is reached, the CNC resumes the execution of the program.
3. OPERATION WITH TWO MOTORS AND 3 AXES.
Machine parameter "P627(8)" indicates whether this feature is available or not.
P627(8)=0This featureis not available.
P627(8)=1This featureis available.
Operation:
The CNC permits using 2 motors to move 3 axes with the following conditions:
One of the axes shared by a motor must be the Z axis and the other one must be either the X or the Y axis.
Only interpolations between the X and Y axes are possible. The Z axis cannot be interpolated with any other axis.
It must be moved alone.
Example: To move the tool from "X0 Y0 Z0" to "X20 Y20 Z20", The CNC will make this move in two steps.
First, it will move the X and Y axes to X20 Y20 and, then, the Z axis to Z20.

4. SPINDLE FOLLOWING ERROR DISPLAYWHILE IN M19
Fromthis versionon, when operatingwith spindle orient(M19), theCNCalso showsthe spindle followingerror on the
screen corresponding to the following error in Automatic and Single block modes.
The Following Error screen shows, in large characters, the amount of axis lag and, under it, the following information
line.
F 00000.0000 & 100 S 0000 % 100 T 00.00 S 0000.000
The last value of this line"S 0000.000"shows the amount of following error (lag) of the spindle when it operates in
spindleorient mode(M19).
5. GANTRYAXES NOT MECHANICALLYSLAVED
Fromthisversionon,dependingonthesettingofmachineparameter"P629(8)",itispossibletoworkwithtwodifferent
types of Gantry axes.
"P629(8)=0" Mechanically slaved Gantry Axes. As until now.
When being homed, both axes behave as a single axis. The CNC takes into account only the parameter
settings and feedback pulses of the main axis, the slaved one being just a follower of the main axis,
"P629(8)=1" Not-mechanically slaved Gantry axes.
When being homed, the two axes behave as separate independent axes. First the main axis is homed
and, then, the slaved one.
6. SHEETMETAL FORMING MACHINES
This feature is available on GP models.
To enable it, set machine parameter "P626(7)=1". The CNC enables functions M98 and M99 to control the X axis
positioning loop.
Function M98 opens the X axis loop and M99 closes it.
When the CNC executes an M30, it also closes the X axis positioning loop.
When operating in jog mode, the CNC enables he following keys to control the X axis positioning loop:
Executes an M98 opening the X axis loop.
Executes an M98 opening the X axis loop.
Executes an M98 closing the X axis loop.
Version 7.2 (April 1997)
1. SCREEN SAVER
The screen saver function works as follows:
After 5 minutes without pressing a key or without the CNC refreshing the screen, the screen goes blank. Press any
key to restore the display.
Machine parameter "P626(5)" indicates whether this feature is to be used or not.
P626(5)=0This feature is not being used.
P626(5)=1This feature is being used.
2. JOGGING FEEDRATE
If while in JOG mode, the conditional input (block skip), pin 18 of connector I/O1, the CNC does not allow entering a
new F value. Only the feedrate override (%) may be varied by means of the MFO switch.

3. PARAMETRIC PROGRAMMING. NEW FUNCTION: F34
Function F34 returns the number of the tool being dealt with.
P27=F34 Parameter P27 takes the value of the new tool being dealt with.
This function must be used when working with a subroutine associated with the tool change.
When using it outside that subroutine, function F34 returns the value of "100".
Version 7.3 (March 1998)
1. PLCI. Input I87
While the CNC is threading (G84), PLCI input I87 is set to “1”.
Note: Input I97 indicates rigid tapping.
Version 7.4 (May 1999)
1. NEW MACHINE PARAMETER ASSOCIATED WITH THE M FUNCTIONS

2. CANCEL TOOL OFFSET DURING ATOOL CHANGE
Fromthis version on, it is possibletoexecute a "T.0" type block insidethesubroutine associated with the tool tocancel
the tool offset. This lets move to a particular position without the need for cumbersome calculations.
Onlythetooloffsetmaybecanceled(T.0)ormodified(T.xx).Thetoolcannotbechanged(Txx.xx)insidethesubroutine

Version 7.6 (July 2001)
1. G75 AFFECTED BY FEEDRATE OVERRIDE
From this version on, there is a new machine parameter indicating whether G75 is affected by the feedrate override or
not. P631(1)=0Not affected. It is always at 100%, like in previous versions.
P631(1)=1It is affected by the Feedrate override.
2. FEEDBACK FACTOR.
Fromthisversionon,thereisanewmachineparametertosettheresolutionofanaxishavinganencoderandaleadscrew.
P819 Feedback factor for the X axis P820 Feedback factor for the Y axis P821 Feedback factor for the Z axis
P822 Feedback factor for the W axis P823 Feedback factor for the V axis
Values between 0 and 65534. The “0” value indicates that this feature is not being used.
Use the following formula to calculate the “Feedback Factor” :
Feedbackfactor=(GearRatioxLeadscrewpitch/NumberofEncoderpulses)x8.192
Examples: GearRatio 1 1 2 1
Leadscrew pitch 5000 6000 6000 8000 (microns)
Encoder 2500 2500 2500 2500 (pulses/turn)
Feedback factor 16384 19660.8 39321.6 26214.4
The machine parameters only admit integer values and sometimes the “Feedback Factor” has decimals. In those cases,
assign the integer part to the machine parameter and use the leadscrew compensation table to make up for the decimal
part.
The values to be entered in the table are calculated with the following formula:
Leadscrewposition=LeadscrewError(microns)xIntegeroffeedbackfactor/decimalsofthefeedbackfactor
Forexample: Gearratio=1Leadscrewpitch=6000 Encoder=2500
Feedbackfactor=19660.8 Machineparameter=19660
For a leadscrew error of 20 microns Leadscrewposition=20x19660/0.8=491520
Going on with the calculation, we come up with the following table.
Leadscrew position Leadscrewerror
P0=-1966.000 P1=-0.080
P2=-1474.500 P3=-0.060
P4=-983.000 P5=-0.040
P6=-491.500 P7=-0.020
P8=0P9=0
P10=491.500 P11=0.020
P12=983.000 P13=0.040
P14=1472.500 P15=0.060
P16=1966.000 P17=0.080
3. NEW MODEL
