P0348 – Motor Overload Protection
Adjustable
Range:
Properties:
Access groups
via HMI:
Description:
This parameter allows the desired protection level for the motor overload function to be configured. Refer to the
table below for details on the actuation of each one of the available options.
P0348
0 = Off
1 = Fault/Alarm
2 = Fault
3 = Alarm
The trip level of the overload protection is calculated internally by the CFW-11, taking into account the motor
current, its thermal class and its service factor. Refer to the parameter P0159 in this section.
P0349 – Motor Overload Alarm Level
Adjustable
Range:
Properties:
Access groups
via HMI:
Description:
This parameter defines the level for the motor overload protection alarm actuation (A046), it is expressed as a
percentage of the trip level of the overload integrator.
It will only be effective if P0348 is programmed in 1 (Fault/Alarm) or 3 (Alarm).

Table 15.2 - Actions for the parameter P0348 options
The overload protection is disabled. Faults or alarms will not be generated for the motor operation
in overload conditions
The inverter will display am alarm (A046) when the motor overload reaches the level programmed
in P0349, and will generate a fault (F072) when the motor overload reaches the overload
protection tripping level
Only the fault (F072) will be generated when the motor overload reaches the overload protection
trip level, and the inverter will be disabled
Only the alarm (A046) is generated when the motor overload reaches the value programmed in
P0349 and the inverter continues operating
