1.2 IndraDrive Mi drive system
1.2.1 Components
KCU02 drive connection box
The KCU02 drive connection box
● supplies the KSM motor-integrated servo drives and the KMS near
motor servo drives
– with power (from the DC bus connection to an HMV supply unit or
HCS converter)
– with 42V control voltage
● with integrated fuses protects the RKH hybrid cable against electric
overload
● allows the higher-level control unit to communicate with the KSM motor-
integrated servo drives and KMS near motor servo drives

⇒ chapter "KMS02 near motor servo drive" on page 3
KMV03 supply unit
The KMV03 supply unit
● supplies the KSM motor-integrated servo drives and KMS near motor
servo drives
– with power
– with 42V control voltage
● allows the higher-level control unit to communicate with the KSM motor-
integrated servo drives and KMS near motor servo drives
