Automatically adjusts the output frequency and output current according to the load to
continue operation without stalling the motor.
• Stall prevention (current limit) level during acceleration (n093)
Sets the stall prevention (current limit) level during acceleration in units of 1%
(Inverter rated current = 100%).
Factory setting: 170%
A setting of 200% disables the stall prevention (current limit) during acceleration.
During acceleration, if the output current exceeds the value set for n093, acceleration
stops and frequency is maintained. When the output current goes down to the value set
for n093, acceleration starts.
In the constant horsepower area [output frequency > max. voltage output frequency
(n013)], the following equation automatically decreases the stall prevention (current
limit) level during acceleration, but the stall prevention level will never go below 40%
of n093.
Preventing Motor from Stalling (Current Limit)
* Stops the acceleration to prevent the motor
from stalling.
† Release width (hysteresis) of stall prevention
during accel is approx. 5% of inverter rated
current.
