Setting Example
An example of stall prevention during deceleration when L3-04 is set to 1 as shown below.
Output frequency
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.
Inverter Capacity
200 V class
E1-01 ≥ 400 V
400 V class
E1-01 < 400 V
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.
