Version 7.1 (July 1996)

1. EXPANSION OF THE INTEGRATED PLC RESOURCES

1.1 INPUTS

1.1.1 AXIS BEING HOMED (REFERENCED)

Input I88 indicates whether a home search is taking place and inputs I100, I101, I102, I103 and I104 indicates which axis is being homed.

I88	Indicates whether any axis is being homed (0=No / 1=Yes)
I100	Indicates whether the X axis is being homed (0=No / 1=Yes)
I101	Indicates whether the Y axis is being homed (0=No / 1=Yes)
I102	Indicates whether the Z axis is being homed (0=No / 1=Yes)
I103	Indicates whether the W axis is being homed (0=No / 1=Yes)
I104	Indicates whether the V axis is being homed (0=No / 1=Yes)

1.1.2 AXIS MOVING DIRECTION

Inputs I42, I43, I44, I45 and I46 will show, at all times, the moving direction of each axis.

	I42	Indicates the moving direction of the X axis (0=Positive / 1=negative)
	I43	Indicates the moving direction of the Y axis (0=Positive / 1=negative)
	I44	Indicates the moving direction of the Z axis (0=Positive / 1=negative)
	I45	Indicates the moving direction of the W axis (0=Positive / 1=negative)
	I46	Indicates the moving direction of the V axis (0=Positive / 1=negative)
1.2	OUTPUTS
1.2.1	ENABLING THE CYCLE-START KEY VIA PLCI

With this feature it is possible to set the treatment of the [CYCLE START] of the CNC via PLCI. Machine parameter "P627(7)" indicates whether this feature is available or not.

P627(7) = 0This featureis not available.

P627(7) = 1This feature is available.

When using this feature, the way the CNC handles the [CYCLE START] key depends on the status of PLCI output O25 (CYCLESTARTENABLE).

O25 = 0 The CNCignoresboth the [CYCLE-START] key and the external [CYCLE-START] signal.

O25 = 1 The CNC takes into account both the [CYCLE-START] key and the external [CYCLE-START] signal.

1.2.2 TRAVEL LIMITS SET VIA PLCI

With this feature, the travel limits of the axes may be set via PLCI. Machine parameter "P627(7)" indicates whether this feature is available or not.

P627(7) = 0This featureis not available.

P627(7) = 1This feature is available.

To set the travel limits for each axis, use the following outputs:

O52 / O53	Positive / negative X axis limits
O54 / O55	Positive / negative Y axis limits
O56 / O57	Positive / negative Z axis limits
O58 / O59	Positive / negative W axis limits
O60 / O61	Positive / negative V axis limits

When the PLCI activates one of this outputs while the axis is moving in the same direction, the CNC stops the axes and the spindle and it displays an axis-travel-limit-overrun error.

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 feature is 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 = 0 Free access to the editor mode (it is protected by current conditions).

O26 = 1 Denied access to the editor mode.

1.2.4 SPINDLE CONTROLLED VIA CNC OR VIA PLCI

From this version on, the spindle analog output may be set either by the CNC or by the PLCI. Machine parameter "P627(7)" indicates whether this feature is available or not.

P627(7) = 0This featureis not available

P627(7) = 1This feature is 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 = 0000 1111 1111 1111	(R1256=4095)	= 10V.
R156 = 0001 1111 1111 1111	(R1256=1)	=-10V.
R156 = 0000 0000 0000 0001		= 2.5 mV.
R156 = 0001 0000 0000 0001		=-2.5mV.

In order for the CNC to assume the value allocated to register R156, one must activate mark M1956 as described in the PLCI Manual (section 5.5.2. Writing internal CNC variables).

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 = 0	Spindle analog output set by the CNC itself.
O27 = 1	Spindle analog output set 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).

It is given in rpm and in hexadecimal format. Example: S 2487 R119= 967

Number of the block in execution (REG120 at the PLCI, M1920 at the PLC64)

It is given in hexadecimal format. 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 whereas R118 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 or more times.

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) = 0	This featureis not available
P627(6) = 1	This feature is available

This function may be selected by the operator. To do this, activate:

On models without PLCI:	pin 7 of connector A5.
On modelswithPLCI:	PLCI output O47

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 feature is 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 DISPLAY WHILE IN M19

From this version on, when operating with spindle orient (M19), the CNC also shows the spindle following error 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 spindle orient mode (M19).

5. GANTRY AXES NOT MECHANICALLY SLAVED

From this version on, depending on the setting of machine parameter "P629(8)", it is possible to work with two different 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.

- 6 -

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

Machine parameter "P629(7)" indicates when the M3, M4, M5 functions are sent out while accelerating or decelerating the spindle.

2. CANCEL TOOL OFFSET DURING A TOOL CHANGE

From this version on, it is possible to execute a "T.0" type block inside the subroutine associated with the tool to cancel the tool offset. This lets move to a particular position without the need for cumbersome calculations.

Only the tool offset may be canceled (T.0) or modified (T.xx). The tool cannot be changed (Txx.xx) inside the subroutine associated with the tool.

3. DIVIDING FACTOR FOR FEEDBACK SIGNALS

Parameters P631(8), P631(7), P631(6), P631(5) and P631(4) are used together with P604(8), P604(7), P604(6), P604(5) and P616(8) which indicate the multiplying factor to be applied to the feedback signals of the X, Y, Z, W, V axes respectively.

X axis	Yaxis	Z axis	W axis	Vaxis
P604(8)	P604(7)	P604(6)	P604(5)	P616(8)
P631(8)	P631(7)	P631(6)	P631(5)	P631(4)
Indicate whether the feedback signals are divided (=1) or not (=0).
P631(8)=0,P631(7)=0,P631(6)=0,P631(5)=0andP631(4)=0				They are not divided
P631(8)=1,P631(7)=1,P631(6)=1,P631(5)=1andP631(4)=1				They are divided by two.

Example:

We wish to obtain a resolution of 0.01 mm with a squarewave encoders mounted on the X axis with 5mm pitch ballscrew Nr of pulses = ballscrew pitch / (Multiplying factor x Resolution)

With P604(8)=0 & P631(8)=0	x4 multiplying factor	Nr of pulses = 125
With P604(8)=1 & P631(8)=0	x2 multiplying factor	Nr of pulses = 250
With P604(8)=0 & P631(8)=1	x2 multiplying factor	Nr of pulses = 250
With P604(8)=1 & P631(8)=1	x1 multiplying factor	Nr of pulses = 500

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.
	From this version on, there is a new machine parameter to set the resolution of an axis having an encoder and a leadscrew.
	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” :
	Feedback factor = (Gear Ratio x Leadscrew pitch / Number of Encoder pulses) x 8.192
	Examples:	Gear Ratio	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:

Leadscrew position = Leadscrew Error (microns) x Integer of feedback factor / decimals of the feedback factor

For example: Gear ratio = 1	Leadscrew pitch = 6000			Encoder = 2500
Feedback factor = 19660.8				Machine parameter = 19660
For a leadscrew error of 20 microns				Leadscrew position = 20 x 19660 / 0.8 = 491520
Going on with the calculation, we come up with the following table.
Leadscrew position		Leadscrew error
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 =	0	P9 =	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

From this version on, the new model MLI is now available.

It offers the same features as the MGI model and it is sold together with the motors and ACS drives..

COMPARISON TABLE FOR MILL MODEL FAGOR 8025/8030 CNCs

8025/8030 MILL MODEL CNCS

Fagor offers the 8025 and 8030 mill type CNCs.

Both types operate the same way and offer similar characteristics. Their basic difference is that the former is compact and the latter is modular.

Both CNC types offer basic models. Although the differences between the basic models are detailed later on, each model may be defined as follows:

8025/8030 GP	Oriented to General Purpose machines
8025/8030 M	Oriented to Milling machines of up to 4 axes.
8025/8030 MG	Same as the M model, but with dynamic graphics.
8025/8030 MS	Oriented to Machining Centers (up to 5 axes).

When the CNC has an Integrated Programmable Logic Controller (PLCI), the letter "I" is added to the CNC model denomination: GPI, MI, MGI, MSI.

Also, When the CNC has 512Kb of part-program memory, the letter "K" is added to the CNC model denomination: GPK, MK, MGK, MSK, GPIK, MIK, MGIK, MSIK.
