System position and limits

The Yaskawa DX100 NSU01 manual identifies JZNC-NSU01 as the Functional Safety Unit (NSU01) for the DX100 system.

The manual states that the unit limits robot operating range, monitors speed and position, and cuts off contactors when a monitoring error is detected.

Inferred system position: The unit sits in the DX100 control panel between robot-motion monitoring signals and safety contactor shutdown.

Unknown: installed wiring, safety configuration, certification basis, and compatibility with a specific controller require separate evidence.

System role

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

Function: Monitors robot-axis range and speed for the DX100 functional-safety system.
System position: The unit sits in the DX100 control panel between robot-motion monitoring signals and safety contactor shutdown.
Upstream / inputs: Receives robot-axis position and speed information from the DX100 system.
Downstream / outputs: Triggers the documented contactor shutdown when a monitoring error is detected.
Limitations: Unknown: installed wiring, safety configuration, certification basis, and compatibility with a specific controller require separate evidence.
