When the output current is higher than the P3-01 (Stall Prevention Level during Acceleration)
level for longer than the time set to P3-16, the drive decelerates using P3-11 (Stall
Deceleration Time during Acceleration). Refer to P3-11 for detais.
The drive reaccelerates when the output current drops 15% below the value set in P3-01.
