the output current is less than L3-02 - 15%. When the time set in L3-27 is expired, the drive starts acceleration
again.
L3-02:
L3-22:
2 : Intelligent (Ignore Decel Ramp)
The drive ignores the acceleration time setting and the drive starts to accelerate in the minimum length of time. The
drive automatically adjusts the acceleration rate to make sure that the output current is not more than L3-02.

(0491)
The stall prevention level set in L3-02 [Stall Prevent Level during Accel] is automatically reduced when the motor is
running within the constant output range. Parameter L3-03 is the limit value used to prevent the stall prevention level
during constant output ranges to fall below the minimum required level.
Note:
The function to automatically reduce the stall prevention level does not operate when L3-01 = 3 [Stall Prevention during Accel = Current
Limit Method].
