Manual and automatic download
With a manual download all necessary parameters excluding the fail-safe parameters (only
with Cus with fail-safe functions) are downloaded into the inverter. A detailed description is
given in "Series Commissioning" in the commissioning section.
With an automatic download even the fail-safe parameters are downloaded into the inverter.
An automatic download can only be performed with an MMC at Start-up or by swapping an
inverter component (CU or PM). A detailed description is given in "Start-up behavior" of this
