reduction
The maximum permissible inverter rated current and the peak current are
specified referred to 400 V mains voltage, a 10/25 m motor cable, a power
stage clock frequency of 4 kHz and an ambient temperature of 45 °C.
If background conditions such as the mains voltage, motor cable length,
power stage clock frequency or ambient temperature change, the max.
permissible current load on the inverter modules also changes. For
details of which current load on the power stage modules is permissible
under which changed background conditions, refer to the following char-
acteristic diagrams and tables.
