Start-up

4.2 Start-up

After all preparatory measures have been carried out and checked the

KEB COMBIVERT can be switched on.

AllcontrolreleasesST(X2A.12)mustbedeactivatedwhenswitchingonthersttime,sincetheCOMBIVERT

R6-Sisnotcustom-specicparameterized.

The following descriptions suppose that the COMBIVERT is on the password level "application mode" (ud.01

= application mode). The selection of the password level is described in the manual chapter 2.2. The start-up

should be executed with COMBIVIS in order to have a short start-up time.

Operating lists are available on the KEB homepage (www.keb.de). This lists contain the necessary parameters

for start-up.

Attention:Thestart-upinstructionmanualcanonlygiveashortoverviewoftheparameteradjustmentswhich

are mandatory necessary to start-up the COMBIVERT.

Thus it represents a check list and not a complete parameter description.

The appropriate chapters of the application manual must be read carefully for exact information about the pa-

rameters,additionallypointstoconsiderandapplication-specicadjustments!

The units are not short-circuit proof without corresponding dimensioned fuses!

Exceeding of the max. rechargeable DC link capacity can lead to a defect!

A load removal in the DC link circle may be done only after the message „ready“.

The wiring must be checked before start-up, particularly the wiring of the control release of the connected

inverters (see page 1.3-8). No parameterizations are needed for power supply operation. A vew parameter

settings are necessary only for regenerative operation.

Activate regeneration

cS.02 Regeneration level (CP.34)

The activation of the regeneration is dependent on the reference value of the DC voltage (ru.18) and the regen-

eration level cS.02 (CP.34).

The regenerative units starts to modulate if the actual DC voltage exceeds the adjusted percentage in cS.02

(CP.34) related to ru.18.

Normally the default value of cS.02 (CP.34) can remain unchanged. A reduction of the level may be necessary

only for very high and very fast increasing regenerative loads.
