Setting of motor electronic thermal protection level 1  (Same as )
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).

The first basic parameter "" (Wizard function) is displayed.
Press either the key or the
.
Press the ENT key to display the parameter setting. (Standard
default setting: 100%)
Press the key to change the parameter to %
(=motor rated current/inverter output rated current x
100=2.0//4.8×100).
Press the ENT key to save the changed parameter.  and the
parameter are displayed alternately.
