X arm GR alignment (find good FP axis & PR3 P/Y).
Go to Commissioning.Doc.
- Select "ALL VIS" in Commissioning.Doc.
Select "CRY-P" for both ITMX and ETMX in ALL VIS.
Select "OL SETPOINT" for ITMX and ETMX in CRY-P.
You can find for both ITMX and ETMX. Right click on slide bar and select “-1” as an increment.
Never select large increment.
- Adjust (IE)TMX alignment to lead their spots on both (IE)TMX to be around center. Ideally, K1:AOS-TMSX_GR_PDA1_OUTPUT should be maximized.
- Or, Maximize K1:AOS-TMSX_GR_PDA1_OUTPUT by adjusting, firstly Yaw of IETMX and secondly Pitch.
- Remember the value of K1:AOS-TMSX_GR_PDA1_OUTPUT (assuming VtmsxGR-0).
- Anyway, move Yaw/ETMX in one direction until you observe slight reduction of VtmsxGR-0.
- Move Yaw/ITMX in both direction to find max of VtmsxGR.
- (4-1) If you can find better VtmsxGR than Vtmsxgr-0, it means your selection for ETMX actuation is good direction.
- (4-2) If worse, bad direction.
- If good, repeat (2) (3) until you encounter (4-2). If bad, select opposite actuation then repeat (2)(3) until you encounter (4-2) again.
- If you find max point, perform (1)~(5) for Pitch/(IE)TMX. (1)~(6) is regarded as one “set” optimization.Ideally, it is better to perform 2 sets for each Yaw/Pitch.
X arm FP axis is established and PR3 P/Y is fixed.
