A new range of OEM subroutines has now been defined.
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

Warning:
14 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.).
With this improvement, it is possible to assign several tools to each
tool position.
TOOLMATY (P164) This g.m.p. is taken into account when using a non-random tool
magazine. It indicates how many tools may be assigned to each
turret position.
15 Improved drive parameter management
From this version on, it also possible to save and load into a
peripheral device or PC the drive parameter tables via Sercos serial
line.
For that, select the parameter page of the desired drive at the CNC
and press the relevant softkey.
A file saved from the CNC via WINDNC may be loaded into the drive
via DDSSETUP and vice versa.
16 User and OEM arithmetic parameters
There are now two new ranges of global arithmetic parameters.
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.
Changing an OEM parameter requires an OEM password.
OEM parameters and subroutines having OEM parameters may
only be written in OEM programs having the [O] attribute.
Since the RPT instruction does not interrupt block preparation or tool
compensation, it may be used when using the EXEC instruction and
while needing to maintain tool compensation active.

Exponential type of
leadscrew
backlash peak
NEW FEATURES
(SOFT T: 8.XX)
On the TC and TCO models, when using OEM parameters in the
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.
17 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.
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.
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.

18 Functions associated to machine safety
18.1 Limit the feedrate of the axes and the spindle speed
It is possible to limit the feedrate of the axes and the spindle turning
speed.
FLIMIT (P75)
SLIMIT (P66)
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.
FLIMITAC (M5058) 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)" .
SLIMITAC (M5059) 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.
When the spindle moves with PLCCNTL, the spindle limitation is
ignored.
18.2 Cycle Start disabled by hardware errors
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.
18.3 Maximum spindle machining speed.
The following safety regulation requires limiting the spindle speed on
lathes:
"A program will not be executed in machining mode unless the maximum
spindle speed value for the part is entered as well as the proper
maximum speed for the part holding fixture for the machine.
If the operator does not enter or validate these speeds every time the
program is changed, it will not be possible to execute the program
machining mode.
The speed cannot exceed the lower speed among the maximum set by
parameter, the maximum set by program and the maximum entered by
hand
A new variable (MDISL) associated with speed limits is now
available to make this safety maneuver easier. It is read-write from
the PLC and read-only from DNC and CNC.

NEW FEATURES
(SOFT T: 8.XX)
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 TC mode.
•In TC 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 TC 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
validated only if it is smaller than the one programmed in MDI.
•When having two main spindles, the speed limit entered will be
valid for both.

19 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
20 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.
•When losing feedback count via Sercos due to broken
communication. Difference greater than 10 microns (0.00039")
or 0.01º
•When changing machine parameters that affect the memory
distribution, for example: number of axes.
In all these cases, a home search must be carried out so the signal
is set back high.
21 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
AND CPS R202 LT R103 ; and "S" limitation from MDI < "S" limitation
from CNC
= CNCWR(R202,PLCSL,M1000) ; Applies "S" limitation from the PLC with the
value set in MDI
;
M100 ; If program in execution
AND CPS R202 GT R103 ; and "S" limitation from MDI > "S" limitation
from CNC
= CNCWR(R210,PLCSL,M1000) ; It does not limit "S" from PLC (R210=0)
;
DFD M100 ; At the end of execution
= CNCWR(R210,PLCSL,M1000) ; it cancels "S" limitation from the PLC
= CNCWR(R210,MDISL,M1000) ; and it resets the MDISL variable
;
END
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.

Synchronize a PLC
axis with a CNC
axis
NEW FEATURES
(SOFT T: 8.XX)
PLC as long as a block or a part-program is not being executed or
simulated.
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:
1. Cancel the tool, TOOL=0 and TOD=0
2. Assign the relevant position using the TMZT variable.
When trying to write in variables TOOL, NXTOOL, TOD and NXTOD
check the OPMODA variable to make sure that no block or part-
program is being executed or simulated. The following bits must be
at "0".
22 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:
•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).
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.

Minimum step "L"
in cycles G83, G60
and G61
•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".
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.
23 Minimum step "L" in cycles G83, G60 and G61
A new "L" parameter has been added to the drilling cycles G83, G60
and G61.
G83 X Z I B D K H C L R
G60 X Z I B Q A J D K H C S L R
G61 X Z I B Q A J D K H C S L R
It is an optional parameter used with "R" values other than "1". It
indicates the minimum value allowed for the drilling peck. If not
programmed, a value of 0 mm is assumed.
24 Threads with different entries
Available when setting s.m.p. “M19TYPE (P43)=1”
A new "V" parameter has been added to the tapping cycles G86 and
G87.
G86-G87: X Z Q R I B D L C J A V
It is an optional parameter that indicates the number of thread
entries to make. If not programmed or programmed with a value of
"0", it means that the thread has only one entry.
25 Error register
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.
26 Proportional and Derivative Gain with the "C" axis
For smoother machining, the proportional and derivative gains are
canceled automatically when machining in the XC and ZC planes.

Path JOG mode
NEW FEATURES
(SOFT T: 8.XX)
CAXGAIN (P163) This g.m.p. lets the OEM decide whether these gains are to be
canceled or not.
With “CAXGAIN (P163) =1”and high values of FFGAIN and
DERGAIN the machine could be jerky depending on the type of part
being machined. In these cases, we suggest to select a gain range
whose FFGAIN AND DERGAIN values small or zero.
27 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 Z
axis.
This feature must be managed from the PLC.
To turn on or off the "Path JOG" work mode, use CNC logic input
“MASTRHND”M5054,
To indicate the type of movement, use CNC logic input
“HNLINARC”M5053
For a linear path, indicate the path angle in the MASLAN variable
(value in degrees between the linear path and the first axis of the
plane)
For an arc, indicate the arc center coordinates in the MASCFI,
MASCSE variables (for the first and second axes of the main
plane)
Variables MASLAN, MASCFI and MASCSE may be read and
written from the CNC, DNC and PLC.
0 They are canceled Default value
1 They are not canceled
M5054 = 0 "Path JOG" function off.
M5054 = 1 "Path JOG" function on.
M5053 = 0 Linear Path
M5053 = 1 Circular path.
