Connection of High-Speed Output Special Adapter

1. When the FX
3U
the main unit should have enough input terminals. Before selecting the main unit, be sure
to check the number of input points needed for the operation.
2. Specify the rotational direction signal of the positioning instruction depending on the
setting of each pulse output destination as shown in the following table:
1st
2nd
3. To output the CLEAR signal using DSZR/ZRN instruction
The CLEAR signal output that is initially set for the DSZR/ZRN instruction is the same output as the direction
signal/reverse pulse train (rotation direction signal). Be sure to specify an output number of another transistor
output using the CLEAR signal
4. If high-speed output special adapter is connected to the FX
numbers will be assigned in the same way as the main unit.
If an output number assigned to a high-speed output special adapter is turned on by the sequence program,
the corresponding output of the main unit will also be turned on. Do not connect a line to both output
terminals. Connect a line to one of the output terminals.
The outputs of the high-speed output special adapter and the main unit will be turned on as shown in the
following table:

*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. Furthermore, use of the PWM (FNC58) is not recommended with the relay type main unit and the
high-speed adapters due to chattering of the relay contacts.
