Analog Input 1 (07.001) is modified by Analog Input 1 Scaling (07.008), Analog Input 1 Offset (07.030) and Analog Input 1 Invert (07.009) before it is routed to its destination as follows:
A1O = Analog Input 1 (07.001) + Analog Input 1 Offset (07.030)
A1O is the value after the offset has been applied and is limited between -100.00% and 100.00%
A1S = A1O x Analog Input 1 Scaling (07.008)
A1S is the value after the scaling and the offset have been applied and is limited between -100.00% and 100.00%
If Analog Input 1 Invert (07.009) = 0 then A1I = A1S otherwise A1I = -A1S

Inverter Temperature (07.034) shows the estimated junction temperature of the hottest power device within the drive inverter. If this temperature exceeds the switch down threshold defined for the power stage the switching frequency is reduced provided this feature has not been disabled (i.e. Auto-switching Frequency Change Disable (05.035) = 0) or the minimum switching frequency has not been reached. The switching frequency can be reduced from 12kHz to 6kHz to 3kHz, or from 16kHz to 8kHz to 4kHz to 2kHz. If the switching frequency has been reduced the drive will attempt to restore it to the required level when the Inverter Temperature (07.034) reduces.

Percentage Of Drive Thermal Trip Level (07.036) gives the percentage of the thermal trip level of the temperature monitoring point or thermal model in the drive that is highest. This includes all thermal monitoring points Stack Temperature (07.004), Auxiliary Temperature (07.005), Inverter Temperature (07.034) and Percentage Of d.c. Link Thermal Trip Level (07.035).
Percentage Of d.c. Link Thermal Trip Level (07.035) is used directly to give Percentage Of Drive Thermal Trip Level (07.036), but for all other monitored values which are temperatures this is given by
Percentage of thermal trip level = (Measured Temperature - 40°C) / (Trip temperature - 40°C) x 100%
The location of the measurement or the thermal model that is related to this temperature is given in Temperature Nearest To Trip Level (07.037). If Percentage Of Drive Thermal Trip Level (07.036) exceeds 90% Drive Over-temperature Alarm (10.018) is set to one. If Percentage Of Drive Thermal Trip Level (07.036) reaches 100% one of the trips given in the table below is initiated. The trip can be reset when the percentage of thermal trip level falls below 95%.
