When using yourproduct,please make sure that you have read this manual, as well as any related manuals
introducedin thismanual, andthat careful attentionis paidto safety and
correct handling of the equipment.
Only safety precautions which applyto this specificproducthave
been noted here. For precautions pertain-
ing tothe PC system, please referto the User’s Manualprovidedwith theCPU unit.

[Precautions Regarding Design]
@DANGER
~ ~ ~ ~ ~ ~~~~~~~~~~~~~
0 A safety circuit should be installed on the exterior of thePC to ensure safe operationof the entire
system even if there is a problem with the external powersupply, or if thePC main unit breaks
down.
Erroneousoutput or operation can result in accidents.
(1) The circuit configuration on the exteriorof the PC should include interlock circuits such as an
emergency stop circuit, upper and lower limitposition detectors, and other circuits to protect
the machinery from damage.
(2) A breakdown inan output unitrelay, transistor, or other component could possiblycause the
output to remain on
or off inappropriately. The circuit configuration should allow external
monitoring of output signalswhere serious accidents could possibly occur.
[Precautions When Disposing of the Equipment]
/9 CAUTION
0 When disposing of this product, it shouM be handled through industrial product disposalchannels.

3. SpeMaations MHd3ZC-A
This sections explains the ON/OFF timing. conditions,and other information pertainingto the
~.. signalsinput to andoutput from the sequiKlWCPU!: ._,.... ..... ,. .
WDT (watchdog timer) em flag WOO)
This isturned ON if a watchdogtimer error is determinedto have occurredby the A64BTL
self-diagnosisfunction. If this happens, alloutput from the A64BTLto external equipment
(Channels1
- 4) istumed OFF. If X00 goes ON, there isa problem with theAWBTL hardware.
External output enabled flags (X01 - XO4)
When Y11 - Y14 (Ch. 1 - 4 external output enable flags) go ON, the ON/OFF position data is
read, and comparison processingis enabled. Following this, X01
- X04 (externaloutput 0 - F
enabled flags) go ON.
Error flag (X05)
This goes ON if one of the errors described in Ch-apter 6 occurs. The X05 flag can be turned L
OFF by cancelling the cause ofthe error and turning ON Y15 @or reset signal).
Disconnected wiring detection flags (X06 - XO9)
These go ON if one of the four channels (CH. 1 - 4) has not been wired or has been discon-
nected, or
if 24 VDC isnot being supplied on the linear scale side. They go OFF automatically
when the problem has been corrected.
Forced output mode instruction (Y10)
Turning on the forcedoutput mode instruction signal initiatesthe forced output modeand
outputs the values in the forced outputdata area (address
78) in the buffer memoryto an
external destination.
POINT
Before using the forced output mode, allof the external output enabled signals shouldbe
turned OFF.
tf any of the external output enabled signals are ON, the forced output modeis
ignored.
If Y10 is turned ON and a forced outputis initiated, external output enabled signals will be
ignored even if they
go ON, and the forced output mode will continueto beeffective.
(6) External output enabled (Y1 1 - Y14)
Turning ON an extemaloutput enabled signal initiates comparison processing of the compari-
son data for CH.
1 - CH. 4 and the counter value, and outputs the results to an external
destination.

3. Speifmtions IWfLSEC-A
(a) The comparison processing is run when Y11 - Y14 are ON. To determine M.ljming at which
the pr&essing is carried out, the last START/STOP input signal during the 2 msec of the INT
output signal cycle is used as the measured value, and the measured value is compared with
the set
value. The results of the comparison are output within 2.8 ms after INT signal is
output.

(b) Up to 4 ON/OFF position data canbe comparedto one measured value, and the results

(c) Turning OFF an external output enabled signal
(Y1 1 - Y14) during output of data to an
external destination causes the corresponding external outputto go
off as well.
(7) Emrreset (Y15)
Turning ON the error reset signal ('Y15) turns OFF the error flag (X05) for the A64BTL error and clears to error
code stored
in the error code area (address 9) of the buffer memory, writing "0 to that address instead.

(8) Zero point correction setting (Y17 - Yl A)
To correct the zeropoint,move the linear scale pointerto the positionto be usedas the zero
point, and turn on whicheversetting (Y17 - Y1 A) correspondsto the linear scale. Thiscom-
pletes correction of the zeropoint. (Always make sure
Y10 and all external output enable
signals are turned OFF.)

NOTE
Of the setting value data for the four ON/OFF positions, if the ON position data of any one data
element is a higher value than the
Off position data (error), no comparison processing can be
carried out for that measured value.If there are no errors in the setting value data for the ON/
OFF positions of any of the other channels, however, comparison processing canbe contin-
ued.

3.4.1 Buffer Memow Allocation
The A64BTL hasa buffer memory for storing data being sentto and received fromthe CPU (this
buffer memory does not have batterybackup).
This section described the buffer memory alloca-
tion and the data configuration.
When the system isbooted, thebuffer memory access instruction should always
be issued through
the sequence program.(When the power supply is turned
off. the values for data writtento this
buffer memory returnto the initial values.)

3.4.2 An Explanation of the Storage Area
(1) Input channel measurement values
The measured values for the supersonic linear scale BTF pointer are stored in addresses 0 -
7. Measured values are carriedto three decimal places and multiplied by 1000.
(Example) A value of 125.371mm will be enteredas “1 25371 ”.
(2) Externaloutput status
The results of a comparison betweenthe measuredvalues for CH. 1 - 4 and the specified
ON/OFF positionsare entered asthe output status.
The table below showsthe relation between the various measured values and the ON/OFF
position data when compared.

POINT
With the A64BTL, measuredvalues (counter values)are sampled at 2-msec intervals.The
measured values are then comparedto the specified ON/OFF positiondata andthe results

Consequently, no externaloutput status
is output for movements occurring with a 2-msec
interval.
