Additional capacitance C
DC_ext
required for HCS02!
For operating HCS02 as a supply unit with low load at the motor
output (P ≤ 10 % × P
DC_cont(HCS02)
; I ≤ 10 % × I
out_cont(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 KCU02 operated at rated power.
KSM/KMS feature power supply monitoring that can be set.

7.1.4 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 "IndraDrive Mi system with HCS01.1E-W0054" on page 293.
7.1.5 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.
