Acceleration
Selects the Stall Prevention method used to prevent
excessive current during acceleration.
0: Disabled - Motor accelerates at active acceleration
rate. The motor may stall if load is too heavy or accel
time is too short.
1: General Purpose - When output current exceeds
L3-02 level, acceleration stops. Acceleration will
continue when the output current level falls below the
L3-02 level.

Deceleration
When using a braking resistor, use setting "0".
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.
4: Overexcitation Deceleration - Decelerates with the
flux level determined by n3-13 (Overexcitation
Gain).

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.
