Setting of motor electronic thermal protection level 1 (Same as f173)
If the capacity of the motor is smaller than the capacity of the inverter, or the rated current of the motor
is smaller than the rated current of the inverter, adjust the electronic thermal protection level 1 so
that it fits the motor's rated current.
* If the indications are in percentages (%), then 100% equals the inverter's rated output current (A).

2) Motor 150%-overload time f607
Parameter f607 is used to set the time elapsed before the motor trips under a load of 150% (overload trip
2) within a range of 10 to 2400 seconds.
3) Inverter overload characteristics
Set to protect the inverter itself. The setting of this parameter cannot be turned to off.
When an inverter overload trip () operates, operation can be improved by lowering stall operating level
, or increasing acceleration time and deceleration time .
