a) Within one operation cycle, if the value is changed to other value than K0, the output maintains the
stop function. In this case, write K0 again for more than one operation cycle, or once turn OFF the
command input.
3) Some restrictions to applicable devices.
S1: <FX
3S, FX3G, FX3GC, FX3U, FX3UC PLCs>
Please specify Y000, Y001, Y002

of transistor output of basic unit, or Y000, Y001, Y002
*3
, Y003
*3
of high speed output special adapter
*2
.
*1. The pulse output destination Y002 is not available in FX
3S, FX3G (14-point and 24-point type)
and FX
3GC PLCs.
*2. High speed output special adapter can be connected only in FX
3U PLC.
*3. When using Y002, Y003 in high speed output special adapter, a second high speed output
special adapter is needed.
Points
• When using FX3U PLC of relay output type or triac output type, high speed output special
adapter is needed.
• The output of high speed output special adapter is a differential line driver.
<FX
1S, FX1N, FX1NC PLCs>
Specify Y000 or Y001.
As the output of the PLC, please use the transistor output.
S2: <FX
3S, FX3G, FX3GC, FX3U, FX3UC PLCs>
When high speed output special adapter is used at the pulse output destination in the FX
3U PLC,
as the rotating direction signal, use the output shown in the table below.
When built-in transistor output is used at the pulse output destination in the FX
3S, FX3G, FX3GC,
FX
3U and FX3UC PLCs, as the rotating direction signal, use the transistor output.
S3: The FX
3U and FX3UC PLCs only are applicable, index (V, Z) decoration is disabled.
S4: The FX
3G, FX3GC, FX3U and FX3UC PLCs only are applicable.
S5: The FX
3U and FX3UC PLCs only are applicable.
4) The output pulse frequency is specified by .
The setting range is as follows.
a) In the case of 16-bit operation
•FX
3S, FX3G, FX3GC, FX3U, FX3UC PLCs
-32,768 to -1, +1 to 32,767 (Hz)
*4
•FX1S, FX1N PLCs
-32,768 to -1, +1 to 32,767 (Hz)
•FX
1NC PLC
-10,000 to -1, +1 to 10,000 (Hz)
b) In the case of 32-bit operation
•FX
3S, FX3G, FX3GC, FX3U, FX3UC PLCs
•FX
1S, FX1N PLCs
-100,000 to -1, +1 to 100,000 (Hz)
•FX
1NC PLC
-10,000 to -1, +1 to 10,000 (Hz)
*4. When operation without acceleration/deceleration (M8338 = OFF), setting range of FX
3S/
FX
3G/FX3GC PLC is -32,768 to -10 Hz, +10 to 32,767 Hz.
*5. When operation without acceleration/deceleration (M8338 = OFF), setting range of FX
3S/
FX
3G/FX3GC PLC is -100,000 to -10 Hz, +10 to 100,000 Hz.
5) Output number of rotating direction signal
Operation changes as follows depending on polarity of output pulse frequency.
