Subfault: 61.72
Description: F-DO 01 Inductive load
Fault class: Output fault
Cause
Measure
Inductance of load connected to safe digital out-
put F-DO 01 too large, or no freewheeling diode
present.
Check the external wiring at safe digital output
F‑DO 01:
– If the load has an inductance, make sure that a
freewheeling diode is present.
– Check the freewheeling diode for proper func-
tioning.
Subfault: 61.81
Description: F-DO 00 Excessive cyclic switching
Fault class: Output fault
Cause
Measure
Failed to complete self-tests at safe digital output
F-DO 00 because of excessive cyclic switching.
Make sure that safe digital output F-DO 00 is
open or closed at least once for at least
2 seconds within 60 seconds.
Subfault: 61.82
Description: F-DO 01 Excessive cyclic switching
Fault class: Output fault
Cause
Measure
Failed to complete self-tests at safe digital output
F-DO 01 because of excessive cyclic switching.
Make sure that safe digital output F-DO 01 is
open or closed at least once for at least
2 seconds within 60 seconds.
Subfault: 61.87
Description: F-DO 00 Undervoltage DC 24 V during diagnostics
Fault class: Output fault
Cause
Measure
Undervoltage of DC 24 V supply voltage detected
during diagnostics of safe digital output F‑DO 00.
– Check the DC 24 V supply voltage (permitted
voltage range, voltage dips).
– If the fault occurs repeatedly, replace the safety
card and send it together with the fault number to
SEW‑EURODRIVE. For further support, contact
SEW‑EURODRIVE Service.
