S1: <FX
3U, FX3UC, FX3G PLCs>
Please specify Y000, Y001, Y002
*1
of transistor output of basic unit, or Y000, Y001, Y002
*3
, Y003
*3
of high speed output special adapter
*2
.
*1. Y002 cannot be used in the 14-point type or 24-point type of FX
3G PLC.
*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, 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
3U, FX3UC, FX3G 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
3U, FX3UC, FX3G
PLCs, as the rotating direction signal, use the transistor output.
S3: FX
3U, FX3UC PLCs only are applicable, index (V, Z) decoration is disabled.
S4: FX
3U, FX3UC, FX3G PLCs only are applicable.
S5: FX
3U, FX3UC PLCs only are applicable.
4) Number of output pulses is specified by .
The setting range is as follows.

-32,768 to +32,767 (excluding 0)
b) In the case of 32-bit operation
-999,999 to +999,999 (excluding 0)
5) The output pulse frequency is specified by .
The setting range is as follows.
a) In the case of 16-bit operation
• In the case of FX
3U, FX3UC, FX3G PLCs
10 to 32,767 (Hz)
• In the case of FX
1S, FX1N PLCs
10 to 32,767 (Hz)
• In the case of FX
1NC PLC
10 to 10,000 (Hz)
b) In the case of 32-bit operation
• In the case of FX
3U, FX3UC, FX3G PLCs
•FX
1S, FX1N PLCs
10 to 100,000 (Hz)
•FX
1NC PLC
10 to 10,000 (Hz)
6) Output number of rotating direction signal
Operation changes as follows depending on polarity of output pulse frequency.
[+ (Positive)] → : ON
[- (Negative)] → : OFF
