For details of braking IGBT trip mode see Pr 10.31 on page 135.
If stop on low priority trips is selected the drive will stop before tripping. Low priority trips are: th, O.Ld1, cL1, and SCL.
This parameter is used to generate user trips over the serial comms. Valid trip codes are numbers which are not values already used by the drive and
are not 100 or 255. Writing a trip code that already exists causes that trip to occur. User generated trips will be indicated by txxx in the trip log where
xxx is the trip code.
Users wishing to reset the drive over the serial comms can do so by writing a value of 100 to this parameter. Writing a value of 255 to this parameter
will cause the trip log to be cleared. When the drive has detected a write to this parameter it immediately writes the value back to zero.
It is not possible to generate UU, EEF or HF trips using Pr 10.38.
This parameter gives an indication of braking resistor temperature based on a simple thermal model, see Pr 10.30 and Pr 10.31 on page 135. Zero
indicates the resistor is close to ambient and 100% is the maximum temperature (trip level). A br.rS warning is given if this parameter is above 75%
and the braking IGBT is active.
The bits in this parameter correspond to the status bits in menu 10 as follows.
