9.3 Function and Operation
→ For details on the maximum speed, bias speed,acceleration time, and deceleration time, refer to
Subsection 4.2.5 to Subsection 4.2.8.
1) For , specify the number of output pulses (relative address value).
2) For , specify the output pulse frequency.
3) For , specify the pulse output number in the range of Y000 to Y003.
4) For , specify the rotation direction signal output device number.
When a high-speed output special adapter is used as a destination for pulse output on a FX
3U PLC, use
the output shown in the following table for rotation direction signals.
When a built-in transistor output is used as a destination for pulse output on a FX
3U/FX3UC PLC, use
transistor output for signals rotation direction.
Setting range
16-bit operation -32,768 to +32,767 (excluding 0)
32-bit operation -999,999 to +999,999 (excluding 0)
Setting range
16-bit operation 10 to 32,767(Hz)
32-bit operation
When a high-speed output special adapter is used 10 to 200,000(Hz)
When a transistor output from the main unit is used 10 to 100,000(Hz)
