Error
code
Designation Response Cause Measure
25 EEPROM SBus communication
stopped
Error while accessing EEPROM Restore factory settings, perform
reset and parameterize DFE again.
Consult SEW service if the error reoc-
curs
28 Fieldbus timeout Default: PO data = 0
Error response
adjustable via P831
No communication between master
and slave within the projected response
monitoring.
• Check communications routine of
the master
• Extend the fieldbus timeout inter-
val (response monitoring) in the
project planning for the master or
deactivate monitoring
37 Watchdog error SBus communication
stopped
Error while executing system software Consult SEW Service.
38 Internal error SBus communication
stopped
Inverter electronics is faulty, possibly
due to EMC influence
Check ground connections and
shielding and correct, if necessary.
Consult SEW service if this error reoc-
curs.
45 Error initializa-
tion
SBus communication
stopped
Error after self-test during reset Perform a reset. Consult SEW service
if the error occurs again.
111 Device timeout
system error
None Check the red system error LED (H1) of
the DFE. If this LED is on, one or sev-
eral nodes on the SBus could not be
addressed within the timeout interval. If
the red system error LED (H1) flashes,
the DFE itself is in an error state. In this
case, error F111 was only reported to
the controller via fieldbus.
Check voltage supply and SBus
cabling, check SBus terminating
resistors. Check the project planning
if the DFE was configured with the
PC. Switch DFE off and on again. If
the error is still present, query the
error via diagnostic interface and per-
form the action described in this table.
