ACS880 and ACS580 Inverter Temperature and Fault/Trip limit in degree C

According to the ACS880 firmware manual the parameter 5.11 is the Inverter Temperature. Here it is in % of the Fault Limit.

We would like to know what the actual fault limit is in deg C. There is no mention of this in the hardware manual of our drives. Even looking at the specific drive type and enclosure. Where can we find the absolute (in deg C) Fault/trip limit of our drives? The reason is that we have many different drives and would like to compare the absolute temperature of the drives and generate statistics for maintenance.
