3.5 Regenerative adjustments
3.5.1 Operating mode
OperatingmodePn.19determines:
- if the unit is a master or a slave
- Unitisoperatedwithcommutationchokeorharmoniclter
Commutation reactor
Advantages Disadvantages
· cheap purchase · only for area of industry
harmoniclter
Advantages Disadvantages
· sine-wave regeneration · high purchase cost
Pn.19: Operating mode
Value Default Note
0:Masterwithcommutationchoke X
For high power regenerative units can be parallel con-
nected.
Here,adevicemustbespeciedasmaster.Allfurther
are adjusted as slave. Single units are always master.

Only one input shall be selected.

ter via input I1, I2 or I3
The input query at 4 or 5 will once held by power on reset.
TheparameterizationfortheKEBstandardcommutationchokeortheKEBstandardharmoniclterispresetby
changing the setting of Pn.19. When using KEB products no further parameter setting is necessary.
3.5.2 Activate regeneration
The activation of the regeneration is dependent on the reference value of the DC voltage (ru.18) and the re-
generation level cS.02.
TheregenerationunitstartstomodulateiftheDCvoltageexceedsthespeciedvalueincS.02,whichisper-
cental related to the reference voltage.
