braking unit or braking resistor). Use this setting when braking units or resistors are connected to
the drive.
 Setting Pr.06-01 to a value > 0 enables the over-voltage stall prevention. This setting refers to
the power supply system and loading. If the setting is too low, then over-voltage stall prevention
is easily activated, which may increase the deceleration time.

 Selection for Stall Prevention
Default: 0
Settings 0: Traditional over-voltage and traditional over-current stall prevention
1: Smart over-voltage and traditional over-current stall prevention
2: Traditional over-voltage and smart over-current stall prevention
3: Smart over-voltage and smart over-current stall prevention

 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.
