K Preventing the Motor from Stalling During Acceleration (Stall Prevention
During Acceleration Function)
The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is placed
on the motor, or sudden rapid acceleration is performed.
If you set L3-01 to 1 (enabled) and the Inverter output current exceeds the -15% level of the set value in L3-
02, the acceleration rate will begin to slow down. When L3-02 is exceeded, acceleration will stop.
If you set L3-01 to 2 (optimum adjustment), the motor current accelerates to the value set in L3-02. With this
setting, the acceleration time setting is ignored.

*Shows the initial value when C6-01 is set to 1. If C6-01 is set to 0, the initial value is 150%.

0: Disabled (Accelerates according to the setting.
Motor may stall if the load is too great.)
1: Enabled (Acceleration stops when the level set
in L3-02 is exceeded. Acceleration restarts
using current value recovery.)
2: Optimum adjustment (Adjusts acceleration
using the level set in L3-02 as the standard.
The acceleration time setting is ignored.)
