P0349 – Level for Alarm Ixt
Adjustable
Range:
70 to 100 % Factory
Setting:
85 %
Properties: cfg
Description:
This parameter defines the level for alarm actuation of the motor overload protection (A0046 when P0037 >
P0349). The parameter is expressed in percentage of the overload integrator limit value, where fault F0072
occurs. Therefore, by setting P0349 at 100 %, the overload alarm is inactive.

Description:
This parameter indicates the present motor overload percentage or overload integrator level. When this
parameter reaches the P0349 value the inverter will indicate the motor overload alarm (A0046). As soon as the
value of the parameter is at 100 %, a motor overload fault (F0072) is raised.
