Setting
The stall prevention level becomes the level set for the constant n094 in
0
all frequency areas.
The following shows that the stall prevention level is automatically
decreased in the constant output range (Max. frequency>Max.
voltage output frequency).
The lower limit is 40% of the set value of n094.

• Accel/decel time selection during stall prevention (n116)
With this function, acceleration/deceleration time when moving to
prevent stalling during operations can be assigned to the two constants,
n021 and n022.

0 Accel / decel time is set by accel / decel time 1 or 2.
1 Accel/decel time is fixed at accel/decel time 2(n021, n022)
• Stall prevention during deceleration (n092)
To prevent overvoltage during deceleration, the inverter automatically
extends the deceleration time according to the value of main circuit DC
voltage. When using an optional braking resistor, set n092 to 1.
