Voltage Sets the time required to return
recovery the Inverter output voltage to
time normal voltage at the comple-
tion of a speed search, in units
L2-04
of one second.
PwrL V/F
Sets the time required to
Ramp t
recover from 0 V to the maxi-
mum voltage.
Undervolt- Sets the main circuit undervolt-
age detec- age (UV) detection level (main
tion level circuit DC voltage) in V units.
Usually setting is not necessary.
L2-05
Insert an AC reactor in the
PUV Det
Inverter input side to lower the
Level
main circuit undervoltage
detection level.
KEB decel- Sets in seconds the time
eration time required to decelerate from the
speed where the deceleration at
L2-06
momentary power loss com-
KEB Fre-
mand (KEB) is input to zero
quency
speed.
Momentary
recovery
Set in seconds the time to
time
accelerate to the set speed after
L2-07
recovery from a momentary
UV
power loss.

Frequency Sets as a percent the about to

gain at KEB the beginning of deceleration at
L2-08 start momentary power loss (KEB).
Reduction = slip frequency

* 1. The factory setting depends upon the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.
* 2. These are values for a 200 V class Inverter. Value for a 400 V class Inverter is double.
* 3. If the setting is 0, the axis will accelerate to the specified speed over the specified acceleration time (C1-01 to C1-08).
