Switching between parameters is done by pressing
and
. Then
press “ENT” to select it, change the parameter value by pressing
and
then press “ENT” to send the parameter to inverter. The LCD will display new
parameters if the setting is successful. Otherwise the old parameters will display on
the LCD.
