Documented product role

Rebuilt from individual evidence

ADEGIS lists 6SN1118-0DG11-0AA0 as a SIMODRIVE 611-D closed-loop plug-in control unit for one axis of digital feed and main-spindle drives without a direct measuring system.

The plug-in unit closes the control loop between the digital drive electronics and one feed or main-spindle axis.

Unknown: installation-specific compatibility, firmware, wiring, and unit condition require separate verification.

System role

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

Function: Controls one digital feed or main-spindle axis in the SIMODRIVE 611-D drive.
System position: Sits as a plug-in control stage between the digital drive electronics and the controlled axis.
Upstream / inputs: Receives control commands and feedback signals from the digital drive system.
Downstream / outputs: Regulates one feed or main-spindle axis through the SIMODRIVE 611-D power stage.
Limitations: Unknown: installation-specific compatibility, firmware, wiring, and unit condition require separate verification.
