BONFIGLIOLI ACTIVE Cube ACU 201-11 User Manual

13.1 Overload Ixt
The admissible load behavior depends on various technical data of the frequency
inverters and the ambient conditions.
The selected Switching frequency 400
defines the rated current and the available
overload for one second and sixty seconds, respectively. The Warning Limi
t Short
Term Ixt 405 and Warning Limit Long Term Ixt 406 are to be parameterized ac-
cordingly.

13.2 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 Warning Limit Heat Sink Temp.407 for the heat sink temper-
ature limit and the
Warning Limit Inside Temp. 408 as an internal tempe
rature limit
are to be parameterized. The temperature value at which a warning message is out-
put is calculated from the type-dependent temperature li
mit 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.
