(Note-1): The 5V(P5)DC power supply from the Q170MCPU 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.
(Note-2): Connect SEL to the SG terminal if the manual pulse generator (differential-output type)
/incremental synchronous encoder is used.
