High-speed output special adapter Can be activated.
• If an output number of the high-speed output special adapter is used (if an output of the high-speed output
special adapter is connected), do not use (connect) the corresponding output terminal of the main unit.
• If an output number of the main unit is used (if an output of the main unit is connected), do not use
(connect) the corresponding output terminal of the high-speed output special adapter.
*1. The output frequency limit of the main unit transistor output is 100 kHz. When operating a load with a pulse
frequency exceeding 100 kHz, PLC failure may occur.
2. Rotation direction signal of positioning instruction
If an FX -2HSY-ADP high-speed output special adapter is used, the rotational direction signal will be
3U
assigned to each pulse output destination device as shown in the following table. Do not assign any other
outputs to these devices using positioning instructions, etc.

3. CLEAR signal and rotation direction signal
If an FX -2HSY-ADP high-speed output special adapter is used, outputs for the rotation direction signal of
3U
the DSZR (FNC150) or ZRN (FNC156) instruction and the CLEAR signal will overlap as shown in the table
above.
For this reason, in order to output the CLEAR signal, change the CLEAR signal device.
4. Pulse output method for high-speed output special adapter
Adjust the pulse output method of the high-speed output special adapter (FX
output method conforms to the command pulse input method of the servo amplifier (drive unit).
If the pulse output method is not properly adjusted, the servo amplifier (drive unit) may not perform the
intended operation.
→ For details on the servo amplifier (drive unit), refer to the manual of the product to be used for your
→ For details on the pulse output method, refer to Subsection 4.6.1 or Subsection 4.5.2.
5. Output pulse frequency (including zero return speed)
Set the output pulse frequency and the zero return speed so that these values can be less than the maximum
frequency value of the servo amplifier (driver unit).
Instruction for outputting pulse train at high speed
If the instruction turns ON, the corresponding output will
be turned on (the corresponding LED will be turned on).
