6.1 Digital terminals
The digital input terminals together with the digital output terminals are located on the X4 plug
connector.
Digital input terminals
The drive controller has 4 parameterisable input terminals (DI1 ... DI4) for detecting digital signals.
The RFR control input for enabling the controller is permanently connected to the device control
unit.
Digital output terminals
The controller has
• a parameterisable output terminal (DO1) for outputting digital signals,
• a relay output (terminal strip X101),

Note!
Initialisation behaviour:
• After mains switching up to the start of the application, the digital output remains set
to FALSE.
Exception handling:
• In case of a critical exception in the application (e.g. reset), the digital output is set to
FALSE considering the terminal polarity parameterised in C00118 .
Switching cycle diagnostics of the relay:
• A reference for evaluating the wear limit can be obtained via the number of switching
cycles of the relay displayed in C00177/2 .
