Protective functions
3.6.1.7 Bus error
The COMBIVERT contains two watchdogs that monitor the communication between an external bus, the ope-
rator, and the inverter control.
With parameter Pn.05 „Response to E.bus“,theresponsetoawatchdogerrorisdened.Dependentonthe
chosen adjustment, either „Error! Watchdog“ (E.buS) or „Warning! Watchdog error“ (A.buS), is issued or a war-
ning message via a digital output is generated.
Watchdog-time (Pn.06)
This watchdog monitors the communication at the operator interface. With an activated watchdog, the response
set under Pn.05 is triggered after expiration of an adjustable time (0.01...40 s) without received telegrams.
Byinputofthevalue„0:off“thefunctionisdeactivated.
HSP5 Watchdog-time (SY.09)
The HSP5 watchdog function monitors the communication of the HSP5 interface (control card - operator; or
control card - PC). The adjusted response in Pn.05 is released if no telegrams after expiration of an adjustable
time (0.01...10 s) arereceived.Value„0:off“deactivates the function.
3.6.1.8 Set selection error
Sets can be locked with Fr.03 „Parameter set lock“. If a disabled set is selected, the inverter remains in the old
set, i.e., no set change occurs.
TheresponsetotheselectionofalockedsetisdenedviaPn.18„E.Setstopping mode“. In the factory setting,
the error „39:Error!Parametersetselection“ (E.Set) is triggered. For Pn.18 = 1...5 a malfunction„102:Warning!
Setselectionerror“(A.Set)isgenerated.ForPn.18=„6:Function disabled“, the drive continues running in the
old set without message.
3.6.1.9 Hardware error
On some inverter types monitorings for the internal hardware (e.g., switch-mode power supply or loading shunt
relay)areintegrated.Ifoneofthesemonitoringcircuitsreportsanerror,„12:generalpowercircuiterror“(E.
PU) is triggered.

error can be reset by writing to SY.3. If the value displayed in SY.03 is
written, only the power-circuit dependent parameters are reinitialized.
If any other value is written, then the default set is loaded. On some
systems after writing Sy.03 a Power-On-Reset is necessary.
