A six-way AND is connected downstream of the output terminal pair of the F-DO; the
signal sources for the inputs of the AND can be selected:
– No function (input set to logical HIGH; default)
If a signal source is not connected to an input, then the input is set to HIGH (default),
exception: If a signal source is not connected at any input, then the output signal = 0.
– Status signals of the drive
For additional information on status signals, see "F-DO overview" in the "Control
signals by way of terminals" chapter.
At the F-DO, the test for the read-back cable can be activated during dormant error
detection and the test mode for the test stop can be selected (for further information, see
Extended Functions in the "Forced dormant error detection" chapter).
Enter a test time. The test time specifies the maximum waiting time for the transient
condition of an external actuator.
