3. 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 of 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 not possible. The pulse output destination changes depending on the 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 adjust the pulse output type setting switch while pulses are being output.
Output affecting
operation
While Y004 is ON, pulses are output from Y000 on the high speed output
adapter.
Y004
While Y004 is OFF, pulses are output from Y004 on the high speed output
adapter.
While Y005 is ON, pulses are output from Y001 on the high speed output
adapter.
Y005
While Y005 is OFF, pulses are output from Y005 on the high speed output
adapter.
While Y006 is ON, pulses are output from Y002 on the high speed output
adapter.
Y006
While Y006 is OFF, pulses are output from Y006 on the high speed output
adapter.
While Y007 is ON, pulses are output from Y003 on the high speed output
adapter.
Y007
While Y007 is OFF, pulses are output from Y007 on the high speed output
adapter.
