13 New range of OEM subroutines.
A new range of OEM subroutines has now been defined.
Available subroutine ranges:
General subroutines SUB 0001 - SUB 9999
OEM subroutines SUB 10000 - SUB 20000
Although OEM subroutines are treated like the general ones, the
have the following restrictions:
They can only be defined in OEM programs, having the [O]
•
attribute. Otherwise, it shows error 63 "Program subroutine
number between 1 and 9999.".
If the subroutine to be executed using CALL, PCALL or MCALL
•
is an OEM subroutine and it is located in a program that does not
the [O] attribute, it will issue Error 1255 "Subroutine restricted to
OEM program".
14 RPT instruction with program number definition
From this version on, the RPT instruction can execute a portion of
the same program or of the indicated program.
8040 CNC
(RPT N(expression), N(expression), P(expression))
The new parameter "P" indicates the number of the program located
in RAM memory containing the two blocks defined by the N labels.
If parameter "P" is not defined, the CNC interprets that the portion
•
to be repeated is located in the same program.
If the defined program number does not exist, it issues Error 69
•
"Program does not exist".
Warning:
Since the RPT instruction does not interrupt block preparation or tool
i
compensation, it may be used when using the EXEC instruction and
while needing to maintain tool compensation active.
15 Improved non-random tool magazine management
When the tool changer is configured as non-random, the tools must
be placed in the tool magazine table in the pre-established order (P1
T1, P2 T2, P3 T3, P4 T4, etc.).
TOOLMATY (P164)

There are now two new ranges of global arithmetic parameters.
User parameters Range: P1000 - P1255.
OEM parameters Range: P2000 - P2255
For compatibility with previous versions, global arithmetic
parameters P100-P299 are maintained and may be used by the
user, by the OEM and by the CNC cycles.
There are now 2 new tables of global arithmetic parameters.
Arithmetic parameter tables available:
GUP Global parameters P100-P299

configuration programs, these programs must have the [O] attribute.
If they don't, an error will be issued when editing a user cycle that
refers to OEM parameters in write mode.
General machine parameters “ROPARMIN” and “ROPARMAX” may
be used to protect any global parameter (user and OEM included)
against being written.
There is no restriction to read these parameters.
18 Exponential type of leadscrew backlash peak
The additional command pulse used to make up for the possible
leadscrew backlash in movement reversals may be rectangular or
exponential.
If the duration of the rectangular pulse is adjusted for low speed, it
could be excessive for high speed or insufficient for low speed when
adjusted for high speed.
Page 10 of 48
In this cases, it is recommended to use the exponential type that
applies a strong pulse at the beginning and decreases in time.
Bit 16 of g.m.p. “ACTBAKAN (P144)” indicates the backlash peak
being used.
0 rectangular leadscrew backlash peak
1 exponential type of leadscrew backlash peak
By default 0
ACTBAKAN (P144)
A finer tuning of the leadscrew backlash consists in testing the circle
geometry and watch for internal peaks when changing quadrants
(left figure). In these cases, it is recommended to set bit 15 of g.m.p.
“ACTBAKAN (P144)” to "1" to eliminate the internal peaks.
Under these conditions, the CNC eliminates the leadscrew backlash
peak as soon as it detects a movement reversal. If the internal peaks
are not eliminated, adjust the leadscrew backlash compensation
better.
It has 16 bits counted from left to right.

speed.
FLIMIT (P75)
SLIMIT (P66)
FLIMITAC (M5058)
SLIMITAC (M5059)
The a.m.p. "FLIMIT" sets the maximum feedrate for each axis and
the s.m.p. "SLIMIT" sets the maximum turning speed for each
spindle.
When the PLC sets this signal high, it limits the feedrate of all the
axes. It does not let any feedrate to exceed the value set by the
corresponding a.m.p. "FLIMIT (P75)" .
When the PLC sets this signal high, it limits the speed of all the
spindles. It does not let any feedrate to exceed the value set by the
corresponding s.m.p. "SLIMIT (P66)" .
The limitation is applied in all work modes, including the PLC
channel. When the mark is high, the CNC applies the limitation and
when going low, it restores the programmed F or S.

19.2 Cycle Start disabled by hardware errors
8040 CNC
If when pressing the Cycle-Start key, a hardware error is detected
(Sercos board error, CAN board error, etc.), the CNC issues the
corresponding error message and does not allow executing or
simulating the program.
19.3 Maximum spindle machining speed.
To limit the spindle speed, use the MDISL variable associated with
speed limits. It is read-write from the PLC and read-only from DNC
and CNC.
This variable is also updated with the programmed S value, in the
following cases:
When programming "G92 S" in MDI mode
•
When programming "G92 S" in ISO code in MC mode.
•
In MC mode, when a new speed limit is defined in the "SMAX"
•
field.
The speed limits entered via CNC, PLC (PLCSL) and DNC (DNCSL)
keep the same functionality and priority unaffected by the new
MDISL variable; in other words, the CNC keeps limiting the spindle
speed like until now.
In order to comply with the safety regulation, it is recommended to
manage from the PLC the variables associated with speed limits as
shown in the following example:

A new part-program cannot be executed without previously
•
entering the speed limit. Otherwise, a message will be displayed.
If the program is executed again, the limit does not have to be
entered again, it is only required when executing the program for
the first time.
While executing a program if a new limit is entered in MDI, the
•
new one will replace the previous one.
In independent MC cycles it is not required to enter the SMAX
•
because it is already defined in each cycle.
If the program being executed already has a G92S, it will be

20 Axes (2) controlled by a drive
Until this version, when having 2 axes controlled by a single drive,
the polarity of the analog output (command sign) always
corresponded to that of the main axis.
From this version on, since sometimes the turning direction of the
two axes may be different, the sign of the command for each axis will
taken into account [the one set by a.m.p “LOOPCHG (P26)”].
Warning
This new version is not compatible with previous versions.
On machines having axes controlled by a single drive the secondary
axis might run away.
Before installing the new software, make sure that the a.m.p.
"LOOPCHG (P26)" of the associated axis has the same value as that of
the main axis.
21 Mandatory home search
The CNC forces a home search on an axis by setting the relevant
REFPOIN* mark low in the following cases:
On CNC power-up
•
After executing SHIFT RESET
•
When the feedback is direct through the axes board and a
•
feedback alarm occurs.

In all these cases, a home search must be carried out so the signal
is set back high.
22 Change of active tool from the PLC
If the tool change process is interrupted, the values of the tool
magazine table and active tool may not reflect the machine's reality.
To update the tool table, variables TOOL, NXTOOL, TOD and
NXTOD that until now were read-only are now read-write from the
PLC as long as a block or a part-program is not being executed or
simulated.
TOOL Number of the active tool
NXTOOL Number of the next tool that is selected, but waiting for the
execution of an M06 to become active.
TOD Number of the active tool offset
NXTOD Number of the offset of the next tool that is selected, but
waiting for the execution of an M06 to become active.
This way, it is possible to resume the tool change from the PLC and
redefine the tool table according to their positions using the TMZT
variable.
To allocate a magazine position to the tool that is considered active
by the CNC and is physically in the tool magazine, proceed as
follows:
Cancel the tool, TOOL=0 and TOD=0

Assign the relevant position using the TMZT variable.

23 Synchronize a PLC axis with a CNC axis
To synchronize an axis of the PLC channel with another one of the
CNC channel (main channel), set a.m.p. SYNCHRO (P3) of the PLC
axis indicating which axis it must synchronize with.
Axis synchronization is carried out from the PLC by activating the
general input "SYNCHRO" of the axis to be coupled as slave (PLC
axis).
To assure that both axes are stopped when they are being
synchronized, we suggest:
Page 14 of 48
To execute a special M function at the CNC so the PLC executes
•
another M function in the PLC channel and activates the general
input "SYNCHRO".
The M function of the main channel must not end until the PLC's
•
M function execution is completed and the ENABLE signal of the
slave axis is set high.
Once both axes are synchronized, it won't be possible to program
movements of the PLC axis. Otherwise, error 1099 will be issued:
"Do not program a slaved axis".
During synchronization, it does not check whether the PLC axis gets
in position or not. For this reason:
The logic output "ENABLE" of the PLC axis is activated (allowing
•
motion).
The logic output "INPOS" of the PLC axis is deactivated (the axis
•
is NOT in position).
General input "INHIBIT" of the PLC axis is ignored, thus not being
•
possible to prevent it from moving.
The execution of the movement of the synchronized slave axis
•
cannot be aborted even by activating the general input
"PLCABORT".
8040 CNC
24 Error register
If an error occurs canceling the "ENABLE" logic outputs of all the
axes, it also cancels the synchronization.
To end synchronization, cancel the "SYNCHRO" general input of the
PLC axis.
To assure that the PLC axis recovers its position after the
synchronization, it is recommended to use other 2 special M
functions, one at the CNC and another one at the PLC.
The "CNC" screen of the "STATUS" mode offers the softkey: [BB].
Pressing this softkey displays the error history indicating the error
number and when it occurred.
This information is very useful to the service technician. Pressing the
[SAVE] softkey requests the number of the CNC program to store
that information.
If the service department asks you for that program, transfer it to a
PC via DNC and send it to the corresponding address via internet.
25 Path JOG mode
It is similar to the "Path Handwheel" mode.
The "Path Handwheel" mode acts at the Handwheel position of the
selector switch whereas the "Path JOG" acts at the continuous and
incremental jog positions of the selector switch.
"Path JOG" may be used to act upon the jog keys of an axis to move
both axes of the plane at the same time for chamfering (straight
sections) and rounding (curved sections).
The CNC assumes as "Path JOG" the keys associated with the X
axis.

29 Improvements in high speed machining
The number of blocks analyzed in advance (look-ahead) has been
increased. From 50 blocks to 75.
The extreme cases have been improved, such as small blocks (of a
few microns) in order to machine faster and more smoothly.
Jerk control can now be applied in Look-ahead, g.m.p. “JERKACT
(P160) and TLOOK (P161)”.
Using Jerk in Look-ahead, a trapezoidal acceleration profile is
applied with a ramp slope equivalent to the maximum jerk of the axis.
The maximum jerk depends on the value assigned to a.m.p.
“JERKLIM (P67)” of that axis and of the axes involved in the
programmed path.
JERKACT (P160)
This parameter has 16 bits counted from left to right.

If "Jerk Control in look ahead" has been selected, the CNC analyzes
the a.m.p “JERKLIM (P67)” of each axis. During look-ahead, the
CNC assumes, for the axes with “JERKLIM (P67)=0”, the value
suggested in that parameter.
TLOOK (P161)
Real block processing time for look-ahead.
If assigned a value smaller than the real one, the machine will vibrate
and if assigned a value greater than the real one the machining
slows down.
Possible values Integers between 0 and 65535 ms
This value is calculated as follows:
Execute, in G91 and G51 E0.1, a program with many small blocks,
at least 1000. For example: “X0.01 Y0.01 Z0.01”.
Measure the program execution time, making sure that the machine
does not vibrate. Divide the execution time by 1000 (or the number
of blocks executed) and assign the resulting value, in microseconds,
to g.m.p. "TLOOK (P161)".

31 Improvement in the tool measuring cycle PROBE1

(PROBE 1, B, I, F, J, K, L, C, D, E, S, M, C, N, X, U, Y, V, Z, W)
Parameters X, U, Y, V, Z, W
They are optional parameters that are not usually necessary.
On certain machines, due to lack of mechanical positioning
repeatability of the probe's, the probe must be calibrated before
each tool calibration.
Instead of redefining machine parameters PRBXMIN, PRBXMAX,
PRBYMIN, PRBYMAX, PRBZMAX, PRBZMIN every time the probe
is calibrated, those coordinates may be indicated in variables X, U,
Y, V, Z, W, respectively.
The CNC does not modify the machine parameters and only takes
into account the coordinates indicated in X, U, Y, V, Z, W during this
calibration.
If any of the X, U, Y, V, Z is left out, the CNC takes the value
assigned to the corresponding machine parameter.

(interrupts the execution for the user to select another tool). N0 (the
cutting edges are not measured separately).

Once the calibration cycle has ended
It uses global arithmetic parameters P298, P299 and assigns the
measured length and radius to the tool offset selected in the tool
offset table.
P298 = measured radius - previous radius (R+I)
P299 = measured length - previous length (L+K)
R = measured radius
L = measured length
I= 0
K= 0
If the dimension of each cutting edge was requested, parameter "N",
the measured lengths are assigned to global arithmetic parameters
P271 and on, and the measured radii to global arithmetic parameters
P251 and on.
Once the wear measuring cycle has ended
When using tool life monitoring, it compares the measured radius
and length values with the theoretical values assigned in the table.
If the maximum allowed is exceeded in any of them, it issues a "tool
rejected" message and acts as follows:
C0 It interrupts the execution for the user to select another tool.
The cycle replaces the tool with another one of the same
family.
C1
It sets the "rejected tool " indicator (status = R)
It activates the general logic output PRTREJEC (M5564)

and radius wear values of the tool offset selected in the tool offset
table.
P298 = measured radius - theoretical radius (R)
P299 = measured length - theoretical length (L)
R = theoretical radius (it maintains the previous value).

If the dimension of each cutting edge was requested, parameter "N",
the lengths are assigned to global arithmetic parameters P271 and

32 Oscilloscope function
The oscilloscope function is a help tool to adjust the CNC and the
drives.
It is possible to represent 4 previously selected variables and
manipulate CNC machine parameters and variables. When using
Fagor Sercos drives, it is also possible to set the parameters of the
drive.

How to operate
Suggestions
When requesting information (variable or parameter) of a drive that
is not connected via Sercos or when having an old software version,
the message "Variable does not exist" will be displayed.
Changing the machine parameters of the CNC and the drive
requires a password.
To access the Oscilloscope mode, select:
Op Mode - Diagnosis - Adjustements - Scope
Define the variables to be analyzed, the trigger conditions and the
machine parameters of the CNC or the drive to be modified.
Execute a part-program moving the axis or axes to be adjusted.
Capture data and then analyze it.
Once data capture has ended, or has been interrupted, it is possible
to analyze the signals and modify the parameters that have been
previously selected, in order to improve the machining conditions.
Capture data, analyze it and modify the parameters again until
achieving the best machining conditions.
Execute endless repetitive movements.

Operation
After adjusting the axis separately, readjust the interpolating axes
together.
It is up to the user to judge what the best adjustment is, the
oscilloscope function is an assistance tool.
To enter or modify a data on the screens, it must be selected and it
must have the editing focus.
