Lust SMARTDRIVE VF1205M - Communication Bus Connections

2-20
2.4.7 LUSTBUS connection (Design C9/ C12)
C9 design:
The VF1000 Series M inverters in this design have a potential-free interface
connection RS485. The inverters can be operated via this interface
according to the LUSTBUS data transmission protocol.
Terminal assignment see Fig.:
An external 24 V DC supply (V
DD
)
is necessary to operate the
interface.
Technical data:
Des. RS485
Voltage supply ext. V
DD
24 VDC ±15%
Current intake I approx. 50 mA
Isolation - corresponds to VDE 0884, Protective low voltage
Driver power - RS485: 31 participants, removal < 1000 m
Bus termination - not installed
Transmission rate - fixed 9600 Baud
C12 design:
The VF1000 Series M inverters
in this design have a potential-
free interface connection
RS232. The inverters can be
operated via this interface
according to the LUSTBUS data
transmission protocol.
Terminal assignment see Fig.:
An external power supply is not
necessary for the operation of
the interface.
