 Setting Pr.06-01 to 0.0 disables the over-voltage stall prevention function (connected with braking
unit or brake resistor). Use this setting when braking units or brake resistors are connected to the
drive.
 Setting Pr.06-01 to a value > 0.0 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 Over-Voltage Stall Prevention
Default: 0
Settings 0: Traditional over-voltage stall prevention
1: Smart over-voltage stall prevention
 Use this function when you are unsure about the load inertia. When stopping under normal load,
the over-voltage does not occur during deceleration and meet the deceleration time setting.
Sometimes it may not stop due to over-voltage during decelerating to STOP when the load
regenerative inertia increases. In this case, the AC motor drive extends the deceleration time
automatically until the drive stops.
 Normal condition: DC bus < Pr.06-01 Over-voltage stall prevention
1. Pr.06-02 = 0:
During deceleration the motor exceeds the synchronous speed due to load inertia. In this case,
the motor becomes an electrical generator. The DC bus voltage may exceed its maximum
allowable value due to motor regeneration in some situations, such as motor’s loading inertia being
too high or drive’s deceleration time being set too short. When you enable traditional over-voltage
stall prevention and the DC bus voltage detected is too high, the drive stops decelerating (output
frequency remains unchanged) until the DC bus voltage drops below the setting value.
