This function must be activated so that the coolant temperature may be taken into account in
the thermal image:
Ambient temperature in the thermal image is taken into account.
Insulation class of winding
Table 3.AF Motor Insulation Class Setting Parameters
Limiting winding temperatures of the three insulations classes: E = 120 °C, B = 130 °C, F =
155°C.
When the ambient temperature is taken into consideration, the insulation class needs to be
programmed for correction of the thermal model. Without using PT100 #7 as the ambient
temperature input, the thermal model bases the thermal calculation on an ambient
temperature of 40°C.
Application
• With large temperature variation (day/night)
• Outdoor installations:
• Pumps
• Conveyors
• Crushers
• Saws
