Note1) If the boost level is too high, an overcurrent fault, overload fault or motor overheating
could occur or the noise could increase.
Note2) The motor current will increase when the boost level is increased. Carefully consider
the settings for the electronic thermal select and setting of current.
(Parameters P06, P07).
ELECTRONIC THERMAL FUNCTION SELECT AND SETTING OF
THERMAL RELAY CURRENT (Parameter P06, P07)
Used to set the operation level of the electronic thermal relay when the motor
overload is detected and the inverter output is to be stopped. Set these parameters
according to the rated current of applicable motor.
