Q
Setting of motor electronic thermal protection level 1
VJT
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
VJT
so
that it fits the motor's rated current.

is set to
[Op-
eration frequency])
CWJ
The first basic parameter “
CWJ
” (history function) is displayed.
VJT
Press either the key or the key to change the parameter to
VJT
.
Press the ENTER 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 ENTER key to save the changed parameter.
VJT
and
the parameter are displayed alternately.
Note:
The rated output current of the inverter should be calculated from the rated current for frequencies below
4kHz, regardless of the setting of the PWM carrier frequency parameter (
H
).
