Quad-peak: Pr136x, Pr144x), and do Homing action.

Step 2: Load the attached example program, and then use the instruments to measure the pitch error of

every compensation point.

Step 3: According to pitch compensation type (uni-directional/bi-directional), and stroke direction of axis

(positive/negative), fill in the table with corresponding type.

Step 4: Measure pitch error again with compensation enabled to verify the result.Compensation table setting
