A.1 Current capacity
of inverter
modules
The maximum permissible inverter output current and the peak current
are dependent on the mains voltage, the motor cable length, the power
stage switching frequency and the ambient temperature. If the conditions
change, the maximum permissible current capacity of the inverter
modules also changes. Refer to the following graphs and tables.
