4. Handling of pulse output terminals in the FX
3UC
-32MT-LT
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 "pulse chain + direction"
(PLS
x
DIR) side.
If the switch is set to "forward rotation pulse chain, reverse rotation pulse chain" (FP
x
RP) side, normal
operations are disabled because the pulse output destination switches depending on the PLC output
status as shown in the table below.
3) Set the pulse output type setting switch while 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.
Use only an output terminal. Do not perform wiring to the unused output terminals.
Outputs in special high speed output adapters and the main unit operate as shown below.

Y000
Y004
While Y004 is ON in PLC, pulses are output from Y000 in high speed output
adapter.
While Y004 is OFF in PLC, pulses are output from Y004 in high speed output
adapter.

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