Description
0: Disabled (Acceleration as set.
With a too heavy load, the motor
may stall.)
1: Enabled (Acceleration stopped
when L3-02 level is exceeded.
Acceleration starts again when
the current has fallen below the
stall prevention level).
2: Intelligent acceleration mode
(Using the L3-02 level as a basis,
acceleration is automatically
adjusted. The set acceleration
time is disregarded.)
Sets the stall prevention during
acceleration operation current level
as a percentage of Inverter rated
current.
Effective when L3-01 is set to 1
or 2.
Usually changing this setting is not
necessary. Reduce the setting when
the motor stalls.
Selects the stall prevention during
running.
0: Disabled (Runs as set. With a
heavy load, the motor may stall.)
1: Deceleration using deceleration
time 1 (C1-02.)
2: Deceleration using deceleration
time 2 (C1-04.)
Set the stall prevention during run-
ning operation current level as a
percentage of the Inverter rated cur-
rent.
Effective when L3-05 is 1 or 2.
Usually changing this setting is not
necessary.
Reduce the setting when the motor
stalls.
Description
Effective when "f /f agree

1", "Frequency detection 1" or
"Frequency detection 2" is set
for a multi-function output.
Effective when "f /f agree
ref out
1", "f /f agree 1" or "Fre-
out set
quency detection 1" or "Fre-
