Your search method is correct.
ctrlX Configurator result is correct. XCS1 W0023 is the smallest converter planned in XCS1 drive family. XMD W0606 or XMS W0006 are inverters, and you can use the DC bus from a XCS1 to power this XMS and XMD.
The missmatch with the other results is due to the current market introduction phase of ctrlX DRIVE with different update cycle for the different information platforms. We are sorry for this.
If searching for converter with current level lower than W0023, take a look at the IndraDrive Cs portfolio, devices are named HCS1.
