<1> Default setting is dependent on parameter o2-04, Drive Model Selection.
<2> Default setting is dependent on parameter E1-01, Input voltage Setting.
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<4> 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.
<5> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives, but
set the value below 1040 Vdc (overvoltage protection level).

Sets the time for the output voltage to return to the preset V/f
pattern during Speed Search.
PwrL V/F Ramp t
Sets the DC bus undervoltage trip level.
PUV Det Level
Sets the time required to decelerate from the speed when KEB
was activated to zero speed.
KEB Decel Time
Sets the time to accelerate to the frequency reference when
momentary power loss is over. If set to 0.0, the active
KEB Accel Time
acceleration time is used.
Sets the percentage of output frequency reduction at the
beginning of deceleration when the KEB Ride-Thru function is
KEB Freq Red
started.
Reduction = (slip frequency before KEB) × L2-08 × 2
Sets the time to perform KEB Ride-Thru.
KEB Detect Time
Sets the desired value of the DC bus voltage during KEB Ride-
Thru.

Used when L3-01 = 1 or 2. 100% is equal to the drive rated
current.
StallP Accel Lvl
Sets Stall Prevention lower limit during acceleration when
StallPAcc LowLim operating in the constant power range. Set as a percentage of
drive rated current.
