(Basic & Applied Instruction)
<FX1S, 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.

10 to 100,000 (Hz)
•FX
1NC PLC
10 to 10,000 (Hz)
6) Output number of rotating direction signal
Operation is as follows by judging the difference between the output pulse frequency (target position) and
present position.
[+ (Positive)] → : ON
[- (Negative)] → : OFF
