200% operation will be started.
The stall operation level can be reduced
0 to 200% when operating at a high speed above the
rated frequency.

0 Second stall prevention operation invalid
0.1 to 200% Second stall prevention operation level.
9999 Same level as Pr.22.
Frequency at which the stall operation
0 to 400Hz
level is started to reduce.
Select whether to use stall prevention or
0 to 31
not according to the acceleration/
100, 101
deceleration status.
Output start time of the OL signal output

When the output current exceeds the limit
level, output frequency is limited to limit
0
current. The inverter rated current is the
reference to the limit level.
When the output torque exceeds the limit
level, output frequency is limited to limit
1
torque. The rated motor torque is the
reference to the limit level.
