This determines the time the drive waits for the residual voltage in the motor to dissipate.
Increase this value if overcurrent or overvoltage occurs at the beginning of Speed Search and
DC Braking.

<1> This is the value for 200V. Double this value for 400V.
<2> The default setting for 400 V drives depends on whether the drive input voltage is higher or lower than 400V.
Note:
1. When setting a value lower than the default, install an AC reactor option on the drive input side to prevent
damage to the drive parts.
 P2-05 Acceleration Time after Uv (Undervoltage )
Sets the time to reaccelerate to the set frequency command after power loss.
When set to 0.0 s, the drive will accelerate to the previously active frequency according to the
active acceleration time set by any of C1-00, C1-02.

P3 Stall Prevention
When the load is too heavy or the deceleration time is too short, the motor may not be able to
keep up with the frequency command and slips. The regenerative power from the power will
then exceed the tolerance of main circuit capacitor and trigger an ov (Overvoltage) fault to
stop the drive. This process is called “stall”. When a motor stalls, it cannot be accelerated or
decelerated. The Stall Prevention Function prevents the motor from stalling and while allowing
