* The given initial value is valid if Heavy Duty is selected (C6-01=0, default setting). If Normal Duty 1 or 2 is selected (C6-01=1 or 2) the initial value will
be 120%.

Stall preven-
tion selec-
tion during
decel
Selects the stall prevention
during deceleration.
0: Disabled (Deceleration as
set. If deceleration time is
too short, a DC-Bus
overvoltage may result.)
1: Enabled (Deceleration is
stopped when the DC-Bus
voltage exceeds the stall
prevention level.
Deceleration restarts when
the voltage falls below the
stall prevention level
again.)
2: Intelligent deceleration
mode (Deceleration rate is
automatically adjusted so
that in Inverter can
decelerate in the shortest
possible time. The set
deceleration time is
disregarded.)
3: Enabled (with Braking
Resistor Unit)
When a braking option (Brak-
ing Resistor, Braking Resistor
Unit, Braking Unit) is used,
always set to 0 or 3.

Stall preven-
tion level
during run
Set the stall prevention during
run operation current level as a
percentage of the Inverter rated
current.
Effective when L3-05 is 1 or 2.
Usually changing this setting is
not necessary.
Reduce the setting when the
motor stalls.
