SIMOVERT MASTERDRIVES
The optional CBC board (Communication Board CAN) is used for
connecting drives to higher-level automation units and other field units
by means of the CAN (Controller Area Network) protocol.

Fig. 8.4-1 View of the optional CBC board
The optional board has three LEDs (green, yellow and red) for
providing information on the current operating status.
It is supplied with voltage via the basic unit.
The CBC can be simply plugged into the electronics box of the
converter and works with all software and hardware output-states of the
MASTERDRIVES converters.
The CBC has a 9-pole Sub-D connector (X458) and a 9-pole Sub-D
socket (X459) for connecting it to the CAN bus. The pins of these
connecting elements are identically assigned and connected through
internally. They are also short-circuit proof and floating.
The CAN (Controller Area Network) protocol is permanently specified in
the international standards recommendation, ISO-DIS 11898. Here,
however, only the electrical part of the physical and the data link layers
are specified (layer 1 and layer 2 in the ISO-OSI-7 layer reference
model). The CiA, with its DS 102-1 recommendation, defines the bus
interface and the bus medium for use as an industrial field bus.
The CBC complies with the specifications in ISO-DIS 11898 and in
DS 102-1.
A data profile for variable-speed drives similar to the VDI/VDE guideline
3689 "PROFIBUS profile for variable speed drives" has not yet been
defined. The specifications of the "PROFIBUS profile for variable speed
drives" are therefore used for the net data.
