n115 0173 Stall pre-
vention
level auto-
matic sup-
pression
selection
Selects whether or not to automatically de-
crease the level for stall prevention during op-
eration if the frequency lies in a constant out-
put range exceeding the frequency set in n013
for max. voltage frequency (a range greater
than the rated motor frequency).
0: Automatic suppression function disabled
(the value of n094 is valid for any frequency)
1: Automatic suppression function enabled.
Note The operation level is decreased by n094
´
(max. voltage frequency/output fre-
quency).
Note The stall prevention function during op-
eration operates according to the accel-
eration/deceleration time set in n116.

n116 0174 Stall pre-
vention ac-
celeration/
decelera-
tion time
setting
Sets the acceleration/deceleration time for the
stall prevention function during operation.
0: Accelerates or decelerates according to
acceleration/deceleration time 1 or 2,
whichever is selected.
1: Accelerates or decelerates according to
acceleration/deceleration time 2.
(n021/n022).
Note When a faster (or slower) acceleration/
deceleration time is desired, set this pa-
rameter to “1” and set the desired accel-
eration/deceleration time for stall preven-
tion operation in acceleration/decelera-
tion time 2.

n117 0175 Undertor-
que detec-
tion selec-
tion
0: Undertorque detection not provided
1: Detected during constant-speed running.
Operation continues after detection.
2: Detected during constant-speed running.
Operation stops during detection.
3: Detected during running. Operation
continues after detection.
4: Detected during running. Operation stops
during detection.
(1)To detect undertorque at accel/decel, set to
3 or 4.
(2)To continue the operation after undertorque
detection, set to 1 or 3.
(3)To stop the inverter by a fault at undertorque
detection, set 2 or 4.
