L3-02
Stall Prevention Level
during Acceleration
This function is enabled when L3-01 = 1 or 2.
Drive rated current is 100%. Decrease the set
value if stalling or excessive current occurs
with default setting.

Stall Prevention Limit
during Acceleration
Sets the lower limit for stall prevention during
acceleration, as a percentage of the drive's
rated current, when operation is in the
frequency range above E1-06 (constant power
region).

Stall Prevention
Selection during
Deceleration
When using a braking resistor, use setting "0".
Setting "3" is used in specific applications.
0: Disabled - The drive decelerates at the active
deceleration rate. If the load is too large or the
deceleration time is too short, an OV fault may
occur.
1: General Purpose - The drive decelerates at
the active deceleration rate, but if the main
circuit DC bus voltage reaches the stall
prevention level (380/760 VDC), deceleration
will stop. Deceleration will continue once the
DC bus level drops below the stall prevention
level.
2: Intelligent - The active deceleration rate is
ignored and the drive decelerates as fast as
possible without hitting OV fault level.
Range: C1-02 / 10.
3: Stall Prevention with Braking Resistor -
Stall prevention during deceleration is enabled
in coordination with dynamic braking.
4: Overexcitation Deceleration - Decelerates
with the flux level determined by n3-13
(Overexcitation Gain).
