P0349 – Level for Alarm Ixt
Adjustable 70 to 100 %
Range:
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.
