The 5V(P5)DC power supply from the Q173PX must not be connected if a separated power
supply is used as the Manual pulse generator/Incremental synchronous encoder power supply.
Use a 5V stabilized power supply as a separated power supply. Any other power supply may
cause a failure.
Connect HPSEL to the SG terminal if the manual pulse generator (differential output type)
/incremental synchronous encoder is used.
