4.4.6 Sizing for Wiring Scheme A

Below is regen system sizing for Wiring Scheme A (Sections 4.4.2.1, 4.4.2.2, and 4.4.3)
by horsepower according to line voltage, motor type, and whether a commutation choke or
harmonic fi lter is used in conjunction with the R6 unit.
i
KEB R6 regen units may be used with third-party drives. When sizing a KEB R6 regen
unit, it may be necessary to know the DC bus capacitance of the drive for proper
regen sizing. The drive DC bus capacitance should not exceed the max. permissable
DC bus capacitance of the R6 unit, according the Technical Data Section 3.1. The
max. permissible DC bus capacitance for mulitple R6 regen units in parallel is added
(e.g. the max. permissible DC bus capacitance of a drive for a single R6 unit is 5,000
uf for 480V operation or 21,500 uf for 230V operation, whereas the max. permissible
DC bus capacitance of a drive when two R6 units in parallel is 10,000 uf for 480V
operation or 43,000 uf for 230V operation).
i
The maximum suggested number of regen units in parallel is three. For larger sizings,
it may be possible to utilize Wiring Scheme B (Sections 4.4.4 and 4.4.5) or a larger
regen size. Contact KEB applications engineering.
i
Sizings with harmonic fi lters must utilize Wiring Scheme A (Sections 4.4.2 and 4.4.3)
and should only be used in combination with harmonic fi lters from KEB.
