2) Motor 150%-overload time limit
The motor 150%-overload time limit parameter is used to set the time elapsed before
the motor trips under a load of 150% (overload trip
) within a range of 10 to 2400 seconds.

3) Inverter overload characteristic
This function is provided to protect the inverter itself and it cannot be changed or
disabled by changing any parameter setting.
If the inverter overload trip function () is activated frequently, this condition can be
improved by changing the setting of the stall prevention level parameter to a
lower level or increasing the acceleration time or the deceleration time .

If the load applied to the inverter exceeds 150% of its rated load or the
operation frequency is less than 0.1Hz, the inverter may trip in a shorter time.
