■ Setting of motor electronic thermal protection level 1
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.
Output current reduction factor
[%]/[A]
Output frequency (Hz)
Note: The motor overload protection start level is fixed at 30Hz.
[Example of setting: When the VFS9-2007PM is running with a 0.4kW motor having 2A rated current ]
Key operated LED display Operation
Displays the operation frequency (perform during stop).
(When standard monitor display selection is set to
[operation frequency])
Press the MON key to display the first basic parameter
(automatic acceleration/deceleration).
Press either the key or the key to change the parameter to
.
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 x 100).
(When PWM carrier frequency is set to 12kHz.)
Press the ENTER key to save the changed parameter.
and the parameter set value are displayed alternately.
