Advantages Disadvantages
· sine-wave regeneration · high purchase cost

Here,adevicemustbespeciedasmaster.Allfurther
are adjusted as slave. Single units are always master.

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.
