10.11.3.5. Case of moving 8-11-9 along inclined motion
Ex. T-axis values are
8 (Step 8)
11 (Step 11) Intermediate point
9 (Step 9)
When the check box is OFF, T-axis is calculated based on 180 degrees fixed.
OXPA-QmV calculates the intermediate point as follows.
Ex. (-120 + 160) / 2 = +20.
It spins 8 to 11 CCW and then 11 to 9 CCW, as the red line shows. Then, T-axis
eventually spins unwontedly from 8 (-120) to 9 (+160).
When the check box is ON, T-axis is calculated based on the soft limits.
OXPA-QmV calculates the intermediate point as follows.
Ex. (-120 + -200) / 2 = -160.
Then, T-axis spins CW along the blue line to prevent from unwanted spinning
from 8 (-120) to 9 (-200).
-120
+20 -160
+160 -200
