Default setting value is 120% when C6-01 is set to 1 (ND) and 150% when C6-01 is set to 0 (HD).
<12>
Default setting value is dependent on parameter o2-04, Drive Model Selection.
<63>
When enabled, the drive stops accelerating when it exceeds the value of L3-02, Stall Prevention Level. The drive
decelerates after 100 ms and begins accelerating again after restoring the current level.
