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, 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).

Stall Prevention
Selection during Run
Selects the Stall Prevention method to use to
prevent drive faults during run.
0: Disabled - Drive runs a set frequency. A
heavy load may cause the drive to trip on an OC
or OL fault.
1: Decel Time 1 - The drive will decelerate at
Decel Time 1 (C1-02) if the output current
exceeds the level set by L3-06. Once the current
level drops below the L3-06 level, the drive will
accelerate back to its frequency reference at the
active acceleration rate.
2: Decel Time 2 - Same as setting 1 except the
drive decelerates at Decel Time 2 (C1-04).
When output frequency is 6 Hz or less, Stall
Prevention during run is disabled regardless of
the setting in L3-05.

Stall Prevention Level
during Run
Enabled when L3-05 is set to "1" or "2". 100%
is equal to the drive rated current.
Decrease the set value if stalling or excessive
current occurs with the default settings.
