When PTRG and IG24 close loop (positively-triggered), the
motor will select related position command to operate in
accordance with the terminal layout POS1~POS4.
When PHOLD and IG24 close loop(positively-triggered), the
motor will stay holding.
When SHOME and IG24 close loop(positively-triggered),
HOME function operates
When ORG and IG24 close loop(positively-triggered), server
will use this as external reference point for home position
returning.
