Faults and Alarms
Description:
The overtemperature protection is carried out by means of the measurement of the temperature with the IGBTs and
power board internal air NTCs, being able to generate alarms and faults.
In order to configure the desired protection, set P0353 according to the table below.
P0353
0 = HS-F/A, Air-F/A
1 = HS-F/A, Air-F
2 = HS-F, Air-F/A
3 = HS-F, Air-F
4 = HS-F/A, Air-F/A *
5 = HS-F/A, Air-F *
6 = HS-F, Air-F/A *
7 = HS-F, Air-F *
(*) Disable alarm (A155) and fault (F156).
P0354 – Fan Speed Fault Configuration
Adjustable
Range:
Properties:

via HMI:
Description:
This parameter allows setting whether a fault or an alarm should take place when the heatsink fan reaches ¼ of the
rated speed. If set to 1, the fault F179 will occur and the inverter will be disabled. If set to 0, the alarm A178 will
occur and the inverter won't be disabled.
