Fail-safe digital input
To enable a safety function via the terminal strip of the inverter, you need a fail-safe digital
input.
For specific default settings of the terminal strip, e.g. default
setting 2, the inverter combines two digital inputs to form one
fail-safe digital input FDI 0.
Which devices are you allowed to connect?
The fail-safe digital input is designed for the following devices:
●
Connection of safety sensors, e.g. emergency stop command devices or light curtains.
●
Connection of pre-processing devices, e.g. fail-safe control systems and safety relays.
Signal state
The inverter expects signals with the same state at its fail-safe digital input:
●
High signal: The safety function is deselected.
●
Low signal: The safety function is selected.
