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.

1.7Manual Feed Axis/Direction Selection Input Signal
+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.

(1) Solid Ta p Mod e Signal
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)
Gear shifting (GRO)
Spindle fixed speed (SO R)
(2) Spindle Position Loop Command
The signal is used to con fig ure the spindle position control loop in the NC.
When thi s input si gn al is “opened”, the CNC configur es the position control loop for the
spindle after confi rm ing that the spindle has stopped. It th en re turns the spindle positio n
control loop mode ou tp ut signa l (SL PS).
(3) Spindle Position Loop Mode Output Signal

(4) Solid Tap Gear Selection Signal
For the machin e equipped withtw0-step gear range , it is possible to execute solid tapping in
both gear ranges A and B (Low and High ). When the signal is “open”, the A gear range is
selected, and when it is “closed”, the B gear range is se lected.
The signal must be set before the designation of the G93 (solid tap command) block. Once set,
the signal status must not b e changed until the solid tap mode is cancelled.

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 )

Since the calendar da ta tre at e d as bi nary data, comparison is possible even if the mo nt h value
exceeds “12”or day value exce ed s “31”.
For example, if the setting for a parameter is “19999999”, and if the CNC calendar data is
“19960715” (July 15 ,1 996), comparison is made as indicated below.

Since the result of compari son is negative, the output i s “0” (status of the calendar).
T o clear the calendar status, reset an appropriate value for a calendar parameter. When a
value greater than the CNC calendar data is et, t h e s tatus of the calendar is cleared.
The parameters used as the calendar parameter are indicated below.

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
movement com m and in the same block, the M de code output signal appe ars only after the

(2)M, S, T and B Function Completion Inut Signals
These input signal s indicate the com leti on of a M,S,T or B command to the CNC.
Output sign als MF, S F,TF and BF are “opened” if input signal FIN is “closed” while th e M,
S, T and B code read (MF A, SF,TF and BF) output signal is “open”. Then, when input signal
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.
2. For T and B codes, there are only bunary outputs and BCD outputs are not given.
