Momentary Power Loss
Minimum Baseblock Time
All Modes
Sets the minimum wait time for residual motor voltage decay before the drive
output reenergizes after performing Power Loss Ride-Thru.
Increasing the time set to L2-03 may help if overcurrent or overvoltage occur
during Speed Search or during DC Injection Braking.
Default:

KEB Acceleration Time
All Modes
Sets the time to accelerate to the frequency reference when momentary power
loss is over. If set to 0.0, the active acceleration time is used.
Default: 0.00 s

<1> Default setting is dependent on parameters C6-01, Drive Duty Selection, and o2-04, Drive Model Selection.
<2> Default setting is dependent on parameter E1-01, Input voltage Setting.
<3> Setting range value is dependent on parameter C1-10, Accel/Decel Time Setting Units. When C1-10 = 0 (units of 0.01 seconds), the setting range
becomes 0.00 to 600.00 seconds.
