Description:
The inverter overload function operates separately from the motor overload protection, and it has the purpose
of protecting the IGBTs and rectifiers in case of overload, avoiding that damage due to overtemperature at their
junctions occurs.
Thus, the parameter P0350 allows configuring the desired protection level for this function, even with the automatic
reduction of the switching frequency, in order to avoid the fault occurrence. The
each of the available options.

P0350
Action
0
It enables F048 – IGBT Overload Fault. In order to avoid the occurrence of the fault, the switching
frequency is reduced automatically to 2.5 kHz
(*)
1
It enables the fault F048 and the alarm A047 – IGBT Overload Alarm. In order to avoid the
occurrence of the fault, the switching frequency is reduced automatically to 2.5 kHz
(*)
2
It enables F048. Without the reduction of the switching frequency
3
It enables the alarm A047 and the fault F048. Without the reduction of the switching frequency
(*)
It reduces the switching frequency when:
- The output current exceeds 1.5 x I
nomHD
(1.1 x I
nomND
);
or.
- The temperature at the IGBT case is less than 10°C from the maximum temperature;
and.
- P0297 = 2 (5 kHz).
