When the cabinet already provides EMC filtering, why pay for more drive?

If the panel carries a cabinet-level EMC solution, or the site does not require per-drive compliance, this unfiltered, no-DC-terminal configuration is the lowest-cost G120X entry — no built-in C2 filter to pay for, no DC-link terminals to wire. It is the right call for short motor cables where voltage reflection is not a concern.

Does my PROFIBUS DP network connect without a gateway?

PROFIBUS DP is onboard, so the drive drops onto an existing Profibus network as a standard node — no communications gateway. For industrial Ethernet use the PROFINET/EtherNet/IP variant; for serial or building buses use the USS/Modbus/BACnet variant.

What if I later need a du/dt filter for longer cables?

The variants with DC terminals (the 1Ux group) add the DC-link connection for an external du/dt filter or braking chopper. This 0UP0 omits them to hit the lowest cost — choose it only when cable runs are short and will stay short.
