Note These parameters are available on 200-V/400-V, 4.0-kW (or less) Inverters (software version
VSP010024 or higher) or 5.5-kW/7.5-kW Inverters (VSP010104 or higher).
Description
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.
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.
0: Undertorque detection disabled
1: Undertorque detection only when speed
coincides and operation continues (UL3
Warning)
2: Undertorque detection only when speed
coincides and output turned OFF (UL3
Fault)
3: Undertorque always detected and operation
continues (UL3 Warning)
4: Undertorque always detected and output
turned OFF (UL3 Fault)
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%.
Used to set the detection time for undertorque.
Undertorque will be detected if a torque that is
equal to or less than the undertorque detection
level continues for the time set here.
