Stall pre-

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.
* The operation level is decreased by n094
×
(max. voltage frequency/output frequency).
* The stall prevention function during opera-
tion operates according to the acceleration/
deceleration time set in n116.

setting
Sets the acceleration/deceleration time for the
stall prevention function during operation.
0: Accelerates or decelerates according to ac-
celeration/deceleration time 1 or 2, whichev-
er is selected.
1: Accelerates or decelerates according to ac-
celeration/deceleration time 2 (n021/n022).
* When a faster (or slower) acceleration/de-
celeration time is desired, set this parameter
to “1” and set the desired acceleration/de-
celeration time for stall prevention operation
in acceleration/deceleration time 2.

Used to set undertorque detection level.
Detection from output torque: Set as a
percentage based on the rated motor torque as
100%.
Detection from output current: Set as a
percentage based on the rated Inverter output
current as 100%.
