Serial interfaces
There are various serial interface options availa-
ble for operation, commissioning and diagnosis,
plus for controlling. For the control and display
panel CDP 312 there is a serial connection X33:/
X34: on the SDCS-CON-2. Three further serial
interfaces are available on the SDCS-AMC-DC
board.
These interfaces use plastic or HCS optical fibres.
One channel is used for drive/PC interfacing.
Another for fieldbus module interfacing. The
third channel is provided for Master-Follower
link or for I/O extension. All three serial interfac-
es are independent from each other.
Fig. 2.5/5: Options for serial communication
Some different SDCS-AMC boards are available to
adapt optical cables, cable length and serial
interfaces. The different SDCS-AMC boards are
equipped with 10 or 5 Mbaud optical transmitter
and receiver devices.
A few basic rules must be considered:
Never mix of 5 Mbd and 10 Mbd devices at the
same cable
5 Mbd can handle only plastic fibre optic
10 Mbd can handle plastic or HCS silicat cable
The branching unit NDBU 95 can enlarge the
maximum distance
The maximum distance and suitable configu-
ration can be select in the manual Configura-
tion instructions NDBU 85-95 - Doc no.:

LED Monitoring Display
If the MultiDrive door Mounting kit is used it is
possible to insert up to three LED monitoring
displays for indicating status as Run, Ready and
Fault and a selectable parameter indicator
(0...150%) per drive. The display is connected to
the SDCS-CON-2 board X33:/X34: or to panel
socket NDPI through a universal Modbus link.
Panel location
There are different possibilities for mounting the
panel:
in the provided aperture of the converter
module
with MultiDrive door mounting kit

Remark:
Fieldbus modules NxxA
(CH0) require the
SDCS-AMC-DC
Classic
board - all others (FCI,
APC2...) require the
SDCS-AMC-DC or SDCS-
AMC-DC Drive Bus board.
