The data in the table refers to an ambient temperature of +40°C and an installation altitude
up to 1000m above sea lev
el. If the environmental conditions are dierent, derating may be
required. You can nd information on this in Section "Derating factors (Page521)".
Larger mounting surfaces improve heat dissipation.
Thermally insulated mounting without additional mounted components
For naturally cooled motors, you must reduce the S1-characteristic curve as follows:
• Reduce the motor static torque by a range of 20% to 30%.
• Reduce the torque at 3000r/min by a range of 40% to 50%.
Thermal motor protection
The converter monitors the motor temperature based on a thermal motor model and issues
the alarm "Motor overtemperature" before the maximum temperature is reached. If the
motor exceeds the maximum temperature, the converter switches o the motor with the
fault message "Motor overtemperature".
If the ambient temperature exceeds 40°C, you need to set the ambient temperature at the
converter so that the motor is reliably protected.
• To do this, select parameter p0613 at the converter.
• Set the maximum ambient temperature that occurs.
Parameter r0034 indicates the thermal load of the motor as a percentage. The reading is
inuenced by the ambient temperature selected in parameter p0613.
You can nd additional information in Section "Parameter list (Page589)".
13.2.5 Derating factors
Overview
Due to the decreasing air pressure in higher installation altitudes, the cooling of the motor
deteriorates. Therefore, reduce the power of the motor as the installation altitude increases.
Multiply the permissible torques or powers by the factors from the following table.
Reduce the torques and powers according to the values determined.
