System role

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

Function: Monitors drive readiness, group fault signals, and enable conditions in a SIMODRIVE 611 infeed assembly.
System position: Sits in the SIMODRIVE 611 infeed assembly between the control signals and the drive power interfaces.
Upstream / inputs: Receives relay, enable, reset, and supply signals from the SIMODRIVE 611 infeed path.
Downstream / outputs: Reports readiness and group status while connecting the documented control and DC-link interfaces.
Limitations: Unknown: installation-specific compatibility, firmware, wiring, and unit condition require separate verification.
