Setting Example
An example of stall prevention during deceleration when L3-04 is set to 1 is shown below.
Fig 6.29 Stall Prevention During Deceleration Operation
Setting Precautions
• The stall prevention level during deceleration differs depending on the inverter rated voltage and input
voltage. Refer to the following table for details.
• When using the braking option (braking resistor, braking resistor units, and braking units), be sure to set
parameter L3-04 to 0 or 3.
• When a braking option is used and the deceleration time shall be optimized (shorter than setting of C1-02/
04/06/08), L3-04 has to be set to 3.
