Start-up

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 rege-

neration 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.

cS.03 mains frequency max. tolerance

If the current mains frequency deviates to the adjusted percentage value of the recognized line frequency

(ru.03), error message „F.nEt“ is displayed. A change of the default value is not necessary.

cS.04 Control angle (degree)

By the control angle (cS.04) the regenerative current can be optimized with an oscilloscope.

The parameter is preset with Pn.19.

Deactivate regeneration

cS.05 Puls off delay, cS.06 puls off level (CP.32)

If the actual power (ru.81/CP.13)exceedsthedenedvalueincS.06 (CP.32), the modulation is switched off

after expiration of the adjusted time in cS.05.

The parameter settings can usually be left at the default settings!

4.2.2 R6-S operation only as regenerative unit

Generally also for operating mode regeneration all relevant parameters of the regenerative unit are preset

whenusingaR6-SunitandKEBcommutationchokeorharmoniclterbasedondefault values, power unit

code and the operating mode Pn.19 (CP.33).

With the interconnection of the R6 for the operation only as regenerative unit, in regenerative operation not only

the regenerative currentowsbackintothemainsbutalsocirculatingcurrentsfromtheinverterviaR6intothe

mains.

These circulating currents are also measured by the R6 and they are detected as regenerative current and thus

also as regenerative power.

In order that the modulation of the regenerative unit is switched off again, parameter cS.06 (CP.32) puls off level

must be parameterized according to the application case after changing from regenerative operation to motor

operation of the drive (incl. non-operation).
