Additional capacitance C
DC_ext
required for HCS02!
For operation as a supply unit with low load at the motor output
(P
out
≤ 10 % × P
DC_cont
; I
out
≤ 10 % × I
out_cont
, where P
out
refers to
KCU02/KSM02/KMS02 and P
DC_cont
to HCS02), the performance
data are available without additional capacitance C
DC_ext
at the
DC bus.
Use additional capacitors C
DC_ext
at the DC bus, if the load at the
motor output is higher.
If the DC bus capacitor unit HLC01.1 is used, the following guide
value applies when determining the additional capacitance
C
DC_ext
:
●
50 μF per kW of installed continuous power KSM/KMS, thus
700 μF for a KCU02 operated at rated power.
The power supply monitoring of KSM/KMS can be set.

7.1.3
Power supply by HCS01
HCS01.1E-W0054 drive controllers can be used to supply power to KSM0x
motor-integrated servo drives or KMS0x near motor servo drives. In this
case, the KCU drive connection box is not required.
See
fig. 9-8 "Rexroth IndraDrive Mi system with HCS01.1E-W0054" on page
.
7.1.4
Power supply by KMV03 and KNK03
KMV03 supply unit, KNK03 mains filter
KMV03 supply units can be used together with KNK03 mains filters to supply
power to KSM0x motor-integrated servo drives or KMS0x near motor servo
drives.
