Setting Example
An example of stall prevention during deceleration when L3-04 is set to 1 as shown below.
Fig 6.23 Stall Prevention During Deceleration Operation
Setting Precautions
•
The stall prevention level during deceleration differs depending on the Inverter capacity. Refer to the fol-
lowing table for details.
•
When using the braking option (braking resistor, Braking Resistor Units, and Braking Units), be sure to set
constant L3-04 to 0 or 3.
•
To decelerate at a shorter time than the deceleration time set when L3-04 is set to 0 with the braking option
enabled, set L3-04 to 3.
•
The setting of L3-04 is ignored for flux vector control or open-loop vector control 2.
