3 Multi-rotation position scale
l Scale starts from the Home position (origin) and extends only in the plus direction. The value returns
to 0 after making the number of revolutions set by “PS” command.
◊ Motor Series : YS, JS1, JS2 and RS
Coordinate values range from 0 to [614 400 × (PS data) -1]
◊ Motor Series : SS
Coordinate values range from 0 to [491 520 × (PS data) -1]
◊ Motor Series : AS, BS and JS0
Coordinates values range from 0 to [409 600 × (PS data) -1]
