 Pr.06-02 (Selection for stall prevention) can be used with Pr.01-49 (Regenerative energy
restriction control method), but Pr.06-02 cannot work with Pr.01-44 (Auto-acceleration and auto-
deceleration setting).
 When Pr.06-02 or Pr.01-49 is enabled (setting value > 0), Pr.01-44 (Auto-acceleration and auto-
deceleration setting) automatically disables (setting value = 0) and cannot be set; when Pr.01-44
is enabled (setting value > 0), Pr.06-02 and Pr.01-49 automatically disable and cannot be set.
 If you use smart over-voltage or smart over-current stall prevention for industries that require fast
response, you can decrease the deceleration time when needed.
 When using smart over-voltage stall prevention, the drive decelerates to stop with the fastest
deceleration time according to different working condition, rather than the first to fourth
deceleration time (Pr. Pr.01-13, Pr.01-15, Pr.01-17, Pr.01-19).
 For 220V / 440V 160 kW models and above, the default for Pr.06-02 is automatically set to 1
(Smart over-voltage and traditional over-current stall prevention). If you need to set the
deceleration time with Pr. Pr.01-13, Pr.01-15, Pr.01-17, Pr.01-19, set Pr.06-02 = 0.
