Remark
Be careful about the counter plan of the noise during the wiring in the pulse output.
1) Use twisted pair shields wire for wiring and execute 3rd contact point.
2) Be sure to separate from the power supply line and I/O lines on which noise usually occurs.
3) Length of wire should be as short as possible.
4) Be sure to use the stable power supply for the pulse output and separate it from I/O power supply.
