Setting of motor electronic thermal protection level 1 thr (Same as f173)
When the capacity of the motor in use 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 thermal protection level 1 thr for the
motor in accordance with the motor's rated current.
* When displaying as a percentage, 100% = rated output current (A) of the inverter is displayed.

The first basic parameter “” (history function) is displayed.
Turn the setting dial to change the parameter to .
Parameter values can be read by pressing the center of the setting
dial (default setting is 100%).
Turn the setting dial to change the parameter to % (= motor
rated current/inverter rated output current ×100=2.0/4.8×100)
⇔
Press the center of the setting dial to save the changed parameter.
and the parameter are displayed alternately.
Note: The rated output current of the inverter should be calculated from the rated output current for
frequencies below 4kHz, regardless of the setting of the PWM carrier frequency parameter
().
