POINT
Use a manual pulse generator or an incremental synchronous encoder that
consumes less than 0.2[A] of current.

(Note-1): The 5V(P5)DC power supply of system must not be used if a separate power supply is applied
to the manual pulse generator/incremental synchronous encoder.
If a separate power supply is used, be sure it is 5V voltage.
Anything else may cause a failure.
