frequency it was runinbefore the power loss.
When using a single drive, set P2-09 = 0 (KEB Operation Method 1) or P2-09 = 1 (KEB
Operation Method 2).
When multiple drives have to perform KEB and decelerate at a curtain speed ratio in
applications such as textile machinery, set P2-09 = 1 (KEB Operation Method 2) or 2 (KEB
Operation Method 3).

P2-01 Minimum Baseblock (bb) Time
Sets the minimum baseblock time when power is restored right after a momentary power loss.
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.


P2-03 Uv (Undervoltage ) Detection Level
Sets the voltage level of undervoltage detection or KEB function activation. Normally this
parameter does not require any change.

P2-03 Uv (Undervoltage ) Detection Level 150 to 210 V

and o2-03<2>
<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.
2. When using KEB function and P2-03 is set too low, the Uv1 (Undervoltage Detection 1) fault will be triggered
before the KEB can be performed. Therefore do not set this value too low.

P2-04 KEB Deceleration Time
Sets the time to decelerate during KEB function. Set a longer time if Uv1 (Undervoltage
Detaction 1) fault is triggered during KEB function. On the other hand, set a shorter time if ov
(Overvoltage) is triggered during KEB function.
·
When performing KEB operation method 1, the drive deceleration time is based on the
setting of P2-04 and changes according to the main circuit voltage.
· When performing KEB operation method 2 or 3, the drive deceleration time is determined
