S ignal s ource for F-DO (p10042)
A six-way AND logic operation is connected downstream of the output terminal pair of the F-
DO; the signal sources for the inputs of the AND can be selected:
● 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 Section "Function of the F-DO" in
Section "Control via TM54F/CU310-2".
S election of the test s ensor f eedback (p10046) and s election of t est mode for forced
dormant error detection (test s top) (p10047)
On the F-DO, testing the readback cable can be activated with dynamic operation and the
test mode for the test stop can be selected (for more information, see Chapter "Forced
dormant error detection (test stop) (Page 160)").
