1.1 F-1 Digit Selection Signal
F-1 Digit F-1 #30076
By the designation of a single-digit number (1 to 9) following address F, the feedrate corresponding to the designa ted numb er is selec ted. Actu al feedrates to be ca lled in res p ond to designated
one-digit numbers are set for setting parameters pm0820 to pm0828.
When the “F1” input signal is in the “closed state”, the currently selected feedrate can b e
increased or dec rea sed by turning the manu a l pu lse generator.
When the “F1” input signal is in the “ope n state”, it is not possible to change the feedrate by
turning the manua l pul se gene ra to r.
IMPORTANT!
1. If the F1 digit fe ed function is selected , it is not possible to designate feedrates of
1mm/min. to 9mm/min. by the F function. In this case, designation is only possible for
feedrates of 10mm/min. or greater.
2. If the dry run swit c h is O N, t he fee dra te set for dry run operation is valid.
3. The feed override functi on is invalid when the F-1 digit feed function is used.
4. Feedrates set f or sett ing parame ters pm08 20 to pm082 8 rema in v alid even if t he p ower
is turne d OFF.
5. Feedrat es ca lled by the designati on F1 di gi t codes are clamped in t he following manner:
If a parameter in the range from pm0820 to pm 0923 exceeds the value set for pm2864, the feedrate to be calle d is cl amped at the valu e set for pm 2865. If a paramet er se tt ing in the range from
pm0824 to pm0828 exceeds the value set for pm2866, the feedrate to be called is clamped at the
value set for pm28 67.
If the value set for the maximum feed rat e se tt in g parameter for F-1 figit fe ed function is greate r
than the valu e set for the maximum feedrate setting parameter for the nor mal F function, the maximum feedrate for the F-1 digit feed func tion is clamped at the feed ra te set fo r the ma ximum feedrate setting parameter for the normal F function.

+X to +5 #30710 to #30714
Manual Feed Axis/Direction Selection Input Signal
-X to -5 #30720 to #30724
The manual feed axis/direction selection input signals determine the direction of axis movement
and the axis to be m oved when the CNC is in t he jog mode, rapid traverse mode or manual step
feed mode.
When the “+” or “-” signals are “closed”, the correspondin g axes are move d. I f more than one
axis is selected, simultaneous axis movement is possible for up to the designated number or
simultaneously controllable axes.
IMPORTANT!
If both the “+” or “-” sig n als of the selec ted axis are “closed” or “opened” at the
same time, the axis cannot be moved. If this occu rs during axis movement, the axis
decelerate s and stops.

The output signa l is in respon s e to the execution. At th e machin e, the spin dle start ( fo r w ard)
signal should be “opened” at this signal. Then return the spindle positin control loop command
input signal (SLPC ) aft er confirming that the spindle has been stopped by t he spind le ze rospeed signal.
IMPORTANT!
1. If the spindle controller has a soft start circuit, cancel it at the same time when the SLPC is
“opened”, since acceleration an d deceleration are controlled by the NC.
2. All of the following input signals must be “closed”.
Spindle reverse rota tion (SINV)

3.1 Calendar Output Signal
Calendar Output Signal CALEN1 TO CALEN4 #35064 TO #35067
By comparing the internal calendar of the CNC with the parameter (date) setting and by
out-pu tting the result of the comparison, it is possible to dispa ly a message such as a regular
maintenance warni n g by using the sequence program.
The calendar is in the CNC. By comp ari ng the ca le ndar t o the data par amete r sett in g, th e
result of the comparison is output. If the parameter setting is smaller than the CNC calendar
value, the signals (CALEN1 to CALEN4) are output corresponding to the pa ram eter used
for comparison.
For such processing, up to fou r parameters can be used to save the ca le ndar data.
The following shows an example of calendar data settin g for a parameter:
pm0905 = 19961 020 (October 20,1996)
pm0906 = 19960 301 (March1,1996 )

Kinds and Addresse s of M, S, T an d B Code Output Signals & Read Output Signals
These are output sign al s for the M, S, T and B commands specified in a program.
If a M, S, T and B command is read during the execution of a part program in the automatic
mode, then CNC outputs the signals according to the numeric value specified with address
M, S, T or B.
Then, the M, S, T or B code read ou tput sig nal is “closed” after the e lapse of the time se t fo r
a parameter.
IMPORTANT!
In the case of an S4 digit comm an d, an S cod e sig na l an d S code read signal are not outpu t
since the output is a 12 bit no-c ont act output or analog out put for a S4 digi t command.
1.M commands for logic circuit processing (M90 to M99)
Neither M code nor MFA code is output. M codes are those for interna l processing of the
CNC, and accordin gly, they cannot be used as external M codes.
2.M decode output signa ls (M00R, M01R, M02R and M30R)
Among the M codes, if M00, M01, M02 or M30 is executed, the corre sponding M decode
output signals (M00R(# 35214); M01R(#35215); M 02R(#35216); M30R( #35 217) appear
in addition to the M code and M code read output signals. The M decode output signal is
“opened” at th e start of automatic operation or when the CNC is res et.
If an M command with a dec ode out put signal is specified to gether/along with an a xis

FIN is “opened” after the confirmation of “opening” of the output signal, the CNC assumes
that the execution of M,S,T or B command has been competed and execures t h ye next step
operation.
IMPORTANT!
1. The M code outptu signal is “opened” when the status of input signal FIN changes
from “closed” to “open”. For the S, T and B code outptut signals, the “open” or “closed ”
state is maintained.

4.3 Gear Range Selection Input and Output Signals
Gear Range Selection Command Output GR1S to GR4S #36504 to #36507
S Function Finish Input SFIN #31117
When an S command is executed, the CNC checks the maximum speed commands of the
individual gear ranges while at the same time it out puts the SF, an d then outputs the gear
selection co mman d (GR1S to GR4S) meet in g th e secified S command.
It then compares the pre s ent gear rang e and returns the FIN if the pres ent gear rang e i s the
same as th e out put gear sele ct ion command. If the gear range must be chang ed, the CNC
enters the gear rang e sel ec t ion sequence. If a fixed speed ou tp ut i s necessa ry for changing
the gear range, the CNC closes the GRO. The CNC outputs the fixed speed signal by giving
top prio rity to this signal.
“Open” the gera range se lection inut signa l ( G R1 to GR4 ) b efore the completi o n of gear
range selection and return the S gear range selection finish (SFIN) at the completion of gear
selection range. The specified spindle speed com m a nd is then output as the non -contact or
D/A output signal.
Then return the FIN when spindle speed agrees with the specified spindle speed.
(1) Gear Selection Sig na l Out put Timing
When an S command is re ad, the contro ller judges whether or no t th e gear range must
be changed and exceutes necessary range selection automatically. How this is exceuted
is shown in the time chart shown in Fig. 4.9.
In this example, gear range of GR@ is selected by the commands of “S1000 M03” and
a new spindle speed command “S2000” is specified which requires the gear range to be
changed to GR 3.
SEQUENCE:
1.The CNC judges tha t ge a r ran ge must be changed to GR 3 and and outputs GR3S signal .
2.At the machine side, this signal (GR3S) should be read by the read-command SF which
has a time delay of “t”, and the gear range should be changed. If the spindle motor must be
rotated to execute gear range change, “open” the GRO.
3.After the com pletion of gear range changing to GR 3, “open” GR3 input and then “open”
SFIN (S command finish in put ).
4.At the time the SFIN is “opened”, a new S command is calculated and sent.

6.1 Input and Output Signals of CNC Operation Modes
(1) Operation Mode Input Signals
These input signals define the operation modes of the CNC by the programmable controller.
For the CNC, the followi ng eight (8) operation modes are provided.
RT #30000 Manual rapid traverse mode
JOG #30001 Manual jog feed mode
H #30002 Manual pulse handle mode
STP #30003 Manual skip feed mode
MDI #30005 Manual da ta input mode
MEM #30006 Memory mode
Manual mode
Automa tic mode
An operation mode is determined by closing one of these input signals.
(a) RT: Manual Rap id Traverse Input Mode
When the “RT” input signal is “closed” with other “open”, the CNC enters the manual
rapid traverse m o de. In this mode, i t controls axis feed accordin g to the inp ut signal of
the manua l fe ed direction and also the rapid override signal.
(b) JOG: Manual Jog Feedra te Sel ec ti on Input Signals
When the “JOG” input signal is “closed” with other inputs “open”, the CNC enters the
manua l jog feed mo d e. In this mode, it controls ax is feed acc o r ding to th e input signal
of the manual feed dire ction.
(c) H: Pulse Handle Mode Input
When the “H” input signal is “closed” with other inputs “open”, the CNC enters the
pulse handle mode. In this mode, it controls axis feed according to axis selection and
the multiply setting signals by operation of the manual pulse generator.
(d) STP: Manual Step Feed Mode Input
When the “STP” input signal is “closed” with other inputs “open”, the CNC enters the
tape mode. In this mode, operation using CNC tape which is read by the ta pe rea der is
enabled.
By setting the appropriate parame t er, it is possible to inp ut a part program from the
RS-232C interface instead of using the tape reader.

(3) Supplements to Operation Mode Input/Output Signals
The items that must be taken into consideration conce rni ng the operatio n mo de input/output
signals ar e indicated below:
1. If an operation mode input signal other than manual mode input signals is given during the
memory mode operation, the CNC stops execution of a part program after the completion
of the block present ly being execute d.
This is also true duri ng a part program executio n in t he tape or MDI mode.
2. If a manual mode input signal is given during the execution of a part program in the memory mode, the following occ urs:
• Axis movment commands
6 - 4
YASNAC PCNC I/O Signal Function Manual Chapter 6: Operation Support Functions
The axes are decelerated and stopped, then the program is interrupted. The remaining
axis movement commands can be continuously executed by turning the automatic start
(ST) inp u t s ignal ON after retu r ning to th e automat ic mode.
• M, S and T commands
These commands are processed depending on the setting for pm 4009D7 (forced FIN
mode selection).
pm4009D7=0 (fo rce d FIN m ode set)
Both the sampling output (MFB to MFE) and the M code output are turned O F F,
and the M S and/or T comm a nd is assumed to have bee n completed. Therefore,
the interrupted M, S and/or T comm ands is not output even when a n automatic
mode is recovered. SPL indicator is not lit.
pm4009D7=1 (fo rce d FIN m ode not set)
The M, S and/or T command is saved and the SPL indicator is lit.
3. If an automatic mode input signal or program edit mode input si gna l is gi ve n w hi le an
axis is moved in a ma nual mode, the ax is is de celerated and stoppe d.
4. An operation mode input is valid if onl y one of the input signal s is “closed”. Under other
status c on ditions , the prev iously selected operation mode remains valid .
If there is no operation mode input signal or if more than one operation mode input signal
is given af ter the power is tur n ed ON, the P CNC ente rs the manual jog feed mode.

Automatic Operation Start Input Signal ST #30030
Automatic Operation Stop Input Signal *SP #30031
Running Output Signal #35370
Stopped Output Signal #35371
(1) Automatic Operation Start Input Signal
By “closing” and the “opening” the ST input signal when the tape, memory, MDI or edit mode
is selected for PCNC operation, the PC NC starts automatic operation to execute a part p rogram. At the same time, it turns the running STL output signal ON.
Note that input of th e ST signa l is ignored in the following states:
• The PCN C is in an alarm state. (al ar m output o r input err or s ignal is ON).
• Automatic operation st op “*SP” input is “opened”.
• External reset “ERS” input is “closed”.
• The RESET button on the operation panel is “closed”.
• Emergency stop “*ESP” is not closed.
• STL signal is output dur ing automatic opera ti on.
(2)Automatic Operation Stop Input Signal
After start o f automatic operation, the PCNC completes automatic operation and turns the
automa tic start (STL) output signal OFF when any of the follow ing state s is satisfied.
• In the MDI mode, exe c ution of a part program is completed by the ma nually input data.
• Execution of one bl ock of a part program is completed with the single-block (SBK ) in put
is “closed”.
• The end of a program (EOP) input is “closed” by the execution of an M command in a part
program.
(3) Running Output Signal
If the automatic o p eration s top input “SP” is “opened” during auomatic operation, axis move ment, etc. is inter ru pt ed an d the r unn ing oupu t si gna l “STL” is opened. Then, the stopped output signal “SPL” is closed.

6.9 Dry Run Input Signal
Dry Run Input Signal DRN #30064
The input signal uses the manua l jog fe edrate selection input signals (JV 1, JV2, JV4, JV8, JV16)
for the execution of a part program in automatic mode.
When a part p rogram is exec uted in automatic mode w i th the DRN i nput signal “closed”, axis
feed is executed not by the feedrate specified in the part progra m but by the feedrate defi ned by
the man ual jog feed rate selection input signa ls .
If the DRN inp u t s ig n a l changes from “open” to “close” or from “closed” to “open” while the
PCNC ise xecuting automatic operation, feed rate is chang ed a ccording to t he s elected feed mode
as indicated below:
• In the “mm/rev” mode: The feedrate is not changed for the block presently executed.
• In the “mm/min” mode: Th e feedrate is chang ed even during th e execution of commands in a
block.
Note: During the execution of a tapping cycle, the feedrate is not changed during the execution
of commands in a block and a new feedra t e be comes valid after the com pl et ion of the
commands in the block.
Concerning a rapid feed, whether the rapid feedrate or jog feedrate is used can be selected
by the setting for a parameter. If rapid feedrate is selected, rapid feedrate override function
is not va lid.
The acceleration/deceleration time constant is not influenced by whether or not the dry run
is turne d ON.

6.10 Machine Lock Input Signal
Machine Lock Input Signal MLK #30066
Axis-depend ent Machine Lock
Input Signal
AMLKX to AMLK5 #30840 to #30844
The machine lock input signal is used to prevent output of the output pulses of the PCNC to servo
units.
The machine lock function is used to check a new program without actually moving the axes.
When the MLK input signal is “closed”, altho ug h t he log ic circui t distributes pulse s , th e axes are
not moved (both in aut om atic and manual mode operations).
Since the logic circuit distributes pulses, the position data is updated as the axis move commands
are executed.
To change the status of the ML K input signal from “closed” to “opened” o r from “opened” to
“closed”, the PCNC must be stopped. In other words, if the MLK input signal stat us should be
changed, the PCNC must be in the Block Stop state or Feed Hold state. If it is changed when the
PCNC is in other states, attempted change is ignor ed.
By using the AMLKX(#30840) to AMLK5(#30844) input signals, the machine lock function can
be called for the individual axes.
If the MLK input signal is “closed” during single-block mode operation, the machine lock function becomes valid afte r the blo ck stops.
6.11 Auxiliary Function Lock Input Signal
Auxiliary Function
Lock Input Signal
The auxiliary fun ct ion lock input signal is us ed to omit the execut ion of the M,S,T and B functions for th e ex ecution of a part program in aut om atic mode.
If the AFL inp ut signal is “closed”, the PCNC ignores the M,S,T and B commands specified in a
part program. The cod e/ de co de output sugnals (M00R, M01R, M02R and M30R) are ou tp ut,
however. Analog D/A signal is also output to the spin dle.
If the AFL input signal status is changed from “opened” to “closed” or from “closed” to “opened”
during the execution of a part program, the program is executed according to the selected AFL
input signal state from the block next to th e one currently bei ng executed.

By using the axis disconnection designation input signals, it is possible todisconnect the
fourth and fifth axes.
For the disconnecte d axies, an alarm is ignored if it occurs to the disconnec t ed axis; the
result is the sam as in the machin e lock state.
IMPORTANT!
1. Axis disc onnection operat ion must be executed only af te r the servo power is turned OF F.
When the axis discon ne ct ion desi gna t ion input signal (DTCH4, DTCH 5) is “closed”
with the servo po wer O N , th e alarm output signa l (AL M ) i s “closed”.
2. When re- inst alli ng an axis which has been disconnected, the power must be OFF and
then ON again.
3. When disconnecting an axis, disconnect th e cable between the AC SERVOPACK
(lamp) and the AC servomotor.
4. If the servo power is turned ON (a fter tu rni ng the servo power ON wi th an axis disconnected), the alarm output signal (ALM) is “closed”.
5. For disconnected axes, over tra ve l i nput signals (*+4 to*+5,* -4 to*-5) are not detected.
6. For disconnected axes, servo power is not turned OFF. Therefore, the servo ON signals
(SVOF4 to SVOF 5) are valid f or s uch axes.

The overtravel input signal indic ates th at the movable machine unit has reached the stroke end.
When the o v ertravel input si g nal is “closed”, axis movment is stopped in the manner as indicated
in Table 10.2, then the al arm output signal ALM is “closed” and the alar m messag e is di sp lay ed
on the screen.

If the overtrave l input signal is “closed”, manually move the r elated axis in the direction opposite
to the “closed” signal direction (jog, manual pulse generat or) until the input signal is “closed”.
After that, execute reset operatio n to close the alarm state output sig na l and clear the alarm
display.
IMPORTANT!
1. Even when an alarm occurred due to the “opening” of the overtravel input signal, the M, S
andT code read outp ut si gna ls MFA, SF and TF are not closed. If it is ne ce ssary to interrupt
the operation b y M, S and T codes after the occu rre nc e of an overtravel al arm , ta ke the interlock by the exter nal sequence.
2. If the overt r a vel alarm occurs, an al arm number in the ra nge from 2001 to 2005 is displ a yed.
In this case, axis move m ent is stopped. (Servo pow er i s not tu rne d O F F.)
Axis movement in the
positive (+) direction stops.
Axis movement in the
negative (-) direction stops.
Movement of all axes and
in all directions are stopp ed.

10.14 Axis Interlock Input Signal
Axis Interlock Inpu t Signa l *ITX to *IT5 #30780 to #30784
The axis interloc k in put signa l is “opened” during axis movement, th e corresponding axis stops
after decel eration. When the signal is “closed” after that, the axis continues moving for the
remaining distance, the program to the next block after the completion of axis movement.
For two or three axis simultaneous interpolati on, if the axis interlock signal of any one of these
axis is “opened”, interpolation pr oce ssin g is prohibited and the axes stop a fter deceleration.
SUPPLEMENT
If this input signal is “opened” while the CNC is in the cy cle start state, the STL remains ope n.
10.15 Direction Specified Axis Interlock Input Signal
Positive direction axis interlock input signa l *+ITX to *+ IT 5 #31040 to #31044
Negative direction axis interlock i nput signal *-IT X to *-I T5 #31050 to #31054
These inpu t signals are interlok input signals which are used to disable axis movement only in the
specified direction. The signal is provided for the individual axes.
If this input signal is “opened” while an ax is is moving, the axis decelerates to a stop. When it is
“closed” in the state the axis stops, the axis continuousl y moves by the remaining dist ance. After
the completion of mo ve me nt s, t he program advances to the ne xt block.
These signals are valid regardless of the operation mode.
If the axis interlock signal (#30780 to #30784) is “open”, axis movement is disables in both the
positive and negative di rec tions disregarding of he status of the direction specified axis interloc k
input signals.
During interpolation operatio n by sim ultaneous mu lt ipl e axis movement s, if a ny one of the input
signals of the corresponding axis movement direction is “opened”, all axes stop after deceleration.
SUPPLEMENT
In the circular interpolation operation, these signals function as the normal axis interlock regardless of the direction of of movement.

10.16 Servo OFF Input Signal
Serv OFF Input Signal SVOFX to SVOF5 #30790 to #30794
The servo OFF input signal is used to clam p an axis mechani ca ll y for carrying out heavy duty
cutting, etc.
When the contact of the signal SVOFX to SV OF5 is ”closed”, the servo lock of the X- to
5th-axis is released. For clamping the machine, use an M function or other appropriate function.
The time chart of the servo OFF signal, mechanical clamp, auxiliary function and servo ready
(SRDX to SRD5) is shown in Fig. 10 .1 . Note t ha t the clamp signal must be output on ly after
the output of the po sit ioning complete signal (DEN).

Follow-up processing is possi bl e by setting an appropriate para m eter.
Follow-up Processing:
If the machine is moved due to mechanical clamping/unclamping operation, the PCNC present
position data is chan ge d so tha t t he error counter value will be “0”, assuming that the co rresponding movement com m and has been given. In thi s ca s e, al tho ugh the machine stays in the offset
position even if the SVOFF sig nal retu rn s to the “opened” state, the machine moves to the cor re ct
position when an absolute command is given next, since the PCNC present position data corresponds to the actual machine position.

Conversely, if follow-up processing is not executed, the mec ha nically moved amo unt remains in
the errorcounter as the serv o contro lled move ment distan ce. In this c ase, the mac hine will move to
cancel this error amount when the servo OFF signal returns to the “closed” state requiring special
attention.
