Configuration for Positioning

If you install the MR-J3-D01 I/O expansion you can use point table posi tion ing, which allows you
to select posi tions from a list of up to 256 table entries with a com bi na tion of eight dig i tal inputs.
Table 4-3 shows how binary input sig nals are encoded to address the point table entries.

Table 4-3: Se lec tion of point ta ble en tries with dig i tal in put signals
In the fac tory default con fig u ra tion the incre men tal sys tem is acti vated, which means that the
abso lute posi tion detec tion sys tem is turned off (PA03 "abso lute posi tion detec tion sys tem").In
this mode the cur rent posi tion is not stored when the power is turned off and you must thus per -
form a home posi tion return every time the ampli fier is pow ered on. The default con fig u ra tion
also uses abso lute tar get posi tions (PA01 "posi tion ing con trol mode").
