3) For , specify the rotation direction signal output device number.
When a high-speed output special adapter is used as a destination for pulse output on a FX
3U PLC, use
the output shown in the following table for rotation direction signals.
When a built-in transistor output is used as a destination for pulse output on a FX
3G/FX3U/FX3UC PLC,
use transistor output for signals rotation direction.
The rotation direction ON/OFF status of the specified device is shown in the following table.
During execution of this instruction, however, do not use the output for other purposes.

ON/OFF status of device
specified by
Rotation direction (increase/decrease current value)
ON
If the number of output pulses specified by is a positive number, the operation
will be performed in the forward rotation direction.
Forward rotation (Outputting pulses from will increase the current value.)
OFF
If the number of output pulses specified by is a negative number, the
operation will be performed in the reverse rotation direction.
Reverse rotation (Outputting pulses from will decrease the current value.)
