Description
Stall prevention operation selection
becomes invalid.
The stall prevention operation level can be
set.
The stall operation level can be reduced
when operating at a high speed above the
rated frequency.
Constant according to Pr. 22
Second stall prevention operation invalid
The stall prevention operation level can be
set.
Same level as Pr. 22.
Set the frequency at which the stall
operation level is started to reduce.
Pr. 156 allows you to select whether to use
stall prevention or not according to the
acceleration/deceleration status.
Set the output start time of the OL signal
output when stall prevention is activated.
Without the OL signal output
When the output current exceeds the limit
level, output frequency is limited to limit
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
current. The rated motor torque is the
reference to the limit level.

resistor or power regeneration converter is
used.
