<1>
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.
<2>
Default setting value is 120% when C6-01 is set to 1 (ND) and 150% when C6-01 is set to 0 (HD).
<3>
This parameter is not reset to the default value when the drive is reinitialized using A1-03.
<4>
The default setting and the upper limit of the setting range are determined by C6-01, Drive Duty Mode, and
L8-38, Carrier Frequency Reduction Selection.
