Operation of the Unit
7. Operation of the Unit
7.1 Operation with PC und system software COMBIVIS
Instructions for the installation and operation of the system software COMBIVIS can be taken
from the appropriate software instruction.
7.2 Switch-on procedure
The COMBIVERT R6-S is initialized after connection of the power supply. The power circuit
identicationischeckedrst.Ifaninvalidpowerunitisrecognized,error„E.Puci”(Powerunit
codeinvalid)isreleasedanddisplayedintheoperator.Thiserrorcannotbereset,thepower
circuit must be checked.
The COMBIVERT R6-S changes into synchronisation phase if a valid power circuit is rec-
ognized. The following procedures happens one after another during this synchronisation
phase:
• Inspectionofcorrectsynchronisationconnection(error"E.nEt"isreleased,ifthesynchro-
noussignalismissing)
• Inspection of the phase allocation of synchronous signals to the mains phases. Error
"E.SYn" is released if a phase is missing or in case of phase allocation failure.
The actual line frequency and the mains voltage is determined after successful synchronisa-
tion. The correct connection of the COMBIVERT R6-S is now ensured. If the control release
(terminalST)isset,theCOMBIVERTR6-Sstartsindependentlywiththenormaloperation.
Depending whether regenerative requirement is available, the COMBIVERT R6-S is in status
„rEGEn”or„Stb”.
Status „Stb“
COMBIVERT R6-S detects a typical voltage level in the DC link circuit of the connected fre-
quencyinverter(motoroperation)andkeepsthemodulationsignalsoftheregenerativeunit
deactivated.
Status „rEGEn”
If the DC voltage in the DC link (CP.09 or ru.19) exceeds the value of the regeneration
level(CP.34orcS.02)referringtothereferencevalueru.18,themodulationsignalsareac-
tivated and the unit changes into regenerative operation. Furthermore the regenerative unit
is switched active, if regenerative operation is requested by an additional installed COMBI-
VERTR6-Sinthesystem(master/slaveoperation).
