Example 
Connection
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.)
