Exact reference: 6SE7022-6TC61-ZG91
Category: Drives / VFD
Evidence checked: 2026-09-12

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Controls motor power using the documented vector-control inverter and PROFIBUS communication option.
System position: Sits between the upstream PROFIBUS machine controller and the downstream motor power circuit.
Upstream / inputs: Receives control data from the upstream machine controller through the documented PROFIBUS option and drive power through the DC link.
Downstream / outputs: Delivers controlled electrical output to the downstream motor circuit.
Limitations: Unknown: installation compatibility and current commercial status require separate confirmation.
