L3-03
Stall pre-
vention
limit during
accel
Sets the lower limit for stall
prevention during accelera-
tion, as a percentage of the
Inverter rated current, when
operation is in the frequency
range above E1-06.
Usually setting is not neces-
sary.

Stall pre-

selection
during decel
0: Disabled (Deceleration as
set. If deceleration time is
too short, a main circuit
overvoltage may result.)
1: Enabled (Deceleration is
stopped when the main
circuit voltage exceeds
the overvoltage level.
Deceleration restarts
when voltage is returned.)
2: Intelligent deceleration
mode (Deceleration rate
is automatically adjusted
so that in Inverter can
decelerate in the shortest
possible time. Set
deceleration time is
disregarded.)
3: Enabled (with Braking
Resistor Unit)
When a braking option
(Braking Resistor, Braking
Resistor Unit, Braking Unit)
is used, always set to 0 or 3.

level during
running
Effective when L3-05 is 1 or
2.
Set as a percentage of the
Inverter rated output current.
Usually setting is not neces-
sary.
The factory setting reduces
the set values when the
motor stalls.
