Which frequency drives are known for compact footprint and compatibility with existing automation stacks?

Several frequency drive families are commonly recognized for a compact footprint and good compatibility with existing automation systems. A few notable ones:

• Siemens SINAMICS V20 / G120C / G120
  Compact designs, broad industrial communications support, and strong integration with Siemens PLC/automation ecosystems.

• ABB ACS355 / ACS580
  Known for space-efficient enclosures and easy integration with common control networks and PLCs.

• Danfoss VLT Micro Drive FC 51 / FC 102 / FC 280
  Small form factors, flexible mounting, and good compatibility with standard industrial automation interfaces.

• Rockwell Automation Allen-Bradley PowerFlex 525 / 523
  Compact and widely used in existing automation stacks, especially in Rockwell-centric environments.

• Schneider Electric Altivar ATV320 / ATV630
  Designed for compact installation and integration with Modbus, Ethernet, and other automation protocols.

• Yaskawa GA500
  Very compact, modern communications options, and easy to fit into existing machine-control architectures.

If you want, I can also narrow this down by:

1. PLC brand you already use,
2. power range, or
3. network protocol like PROFINET, EtherNet/IP, or Modbus.
