SINAMICS general: Sinamics drive s120 F07860 Issue

Hi,
We have a crane hoist that is using a 6SL32101SE260AA0 power module that keeps overheating it's braking resistor.  We keep getting an external fault F07860 on the drive. It is an external fault coming in via binector p2106, but I am unsure how to trace the source of this in PLC? I assume it is coming from the thermostatic switch in the resistor but I need to trace the fault code to be certain.
Could anyone give me some tips on how to trace this fault?
Thank you in advance.
