Temperature

The ambient conditions and the energy dissipation at the current operating point
result in the frequency inverter heating up. In order to avoid a fault switch-off of the
frequency inverter, the
ature limit and the
are to be parameterized. The temperature value at which a warning message is out-
put is calculated from the type-dependent temperature limit minus the adjusted
warning limit.
The switch-off limit of the frequency inverter for the maximum temperature is an
internal temperature of 65 °C and a heat sink temperature of 80 °C – 90 °C.
No.
