LCD
Ridethrough time, when
Momentary Power Loss
Selection (L2-01) is set to 1,
in units of seconds.
Sets the Inverter's minimum
baseblock time in units of
one second, when the
Inverter is restarted after
power loss ridethrough.
Sets the time to approxi-
mately 0.7 times the motor
secondary circuit time con-
stant.
When an overcurrent or
overvoltage occurs when
starting a speed search or DC
injection braking, increase
the set values.
Sets the time required to
return the Inverter output
voltage to normal voltage at
the completion of a speed
search, in units of one sec-
ond.
Sets the time required to
recover from 0 V to the max-
imum voltage.
Sets the main circuit under-
voltage (UV) detection level
(main circuit DC voltage) in
V units.
Usually setting is not neces-
sary.
Insert an AC reactor in the
Inverter input side to lower
the main circuit undervolt-
age detection level.
Sets in seconds the time
required to decelerate from
the speed where the deceler-
ation at momentary power
loss command (KEB) is
input to zero speed.
Set in seconds the time to
accelerate to the set speed
after recovery from a
momentary power loss.
