4. Handling of pulse output terminals in FX
The outputs Y000 and Y001 are the high-speed
response type.
When using a pulse output instruction or
positioning instruction, adjust the load current of
the open collector transistor output to about 10 to
100 mA (5 to 24V DC).
When the load is smaller, connect a dummy
resistor in parallel to the outside of a used output
terminal (Y000 or Y001) as shown in the circuit
diagram below so that the specified current
shown above flows in the output transistor.
5. Cautions on using special high-speed output adapters
1)
Outputs of special high-speed output adapters work as differential line drivers.
2)
Set the pulse output type setting switch in a special high-speed output adapter to the "pulse chain + direction"
(PLS DIR) side.
If the switch is set to the "forward rotation pulse chain reverse rotation pulse chain" (FP RP) side, normal
operations are disabled. The pulse output destination changes depending on the PLC output status as shown in
the table below.

3)
Set the pulse output type setting switch while the PLC is stopped or while the power is OFF.
Do not manipulate the pulse output form setting switch while pulses are being output.
4)
When special high-speed output adapters are connected, the same output numbers in the main unit are assigned
as shown in the table below.
Only wire the appropriate output terminals.
Outputs in special high-speed output adapters and the main unit operate as shown below.

While Y004 is ON, pulses are output from Y000 in the high-speed output adapter.

While Y004 is OFF, pulses are output from Y004 in the high-speed output adapter.
While Y005 is ON, pulses are output from Y001 in the high-speed output adapter.
