Disabled. (Accelerate according to the settings. Stalls may occur with large loads.)
1
Enabled. (Stop acceleration if L3-02 setting is exceeded. Accelerate again when current recovers.)
2
Intelligent. (Adjust acceleration so that the L3-02 isn’t exceeded by much. Ignore the acceleration
time setting.)
•
When setting 1 (enabled) is selected, acceleration is stopped if the motor current exceeds the accel-
eration stall prevention level. Acceleration is started again when the current falls below this level.
•
When setting 2 (intelligent) is selected, acceleration is performed using the the acceleration stall pre-
vention level as a basis. In this case, the acceleration time is ignored.

Note 1. This parameter cannot be changed during operation.
Note 2. N.A. = Not applicable.
•
This setting is valid when L3-01 is set to 1 or 2.
•
There is normally no need to change this setting.
•
Decrease this setting when the motor’s capacity is small compared to the Inverter’s capacity or stalling
occurs when the motor is operated with the default setting. The standard target setting is 2 to 3 times
the motor’s rated current. (Set this current value as a percentage of the Inverter’s rated current, i.e.,
100% corresponds to the Inverter’s rated current.)
