Soft-Starter SSW-06 Characteristics on Fieldbus Network

2.2.5 Drive Connection to the DeviceNet Network
To interconnect the different network nodes, we recommend realizing the equipment connection direct to the
main line without the use of shunts.

The passage of the DeviceNet network cable must be laid separately (and if possible distant) from the power
supply cables. All drives shall be grounded properly, preferably on the common grounding connection. Also the
DeviceNet cable shield must be grounded in an only point to the source that supplies the bus.
2.2.6 Termination Resistor
The DeviceNet network must be fitted with terminations resistors at the ends of the main bus. The termination
resistor must provide a resistance of 121Ω / 0,5W. Each resistor must connect the CAN_H and CAN_L signal
(pins 2 and 4 of the connector), and they can be disposed on the same connector that connects the equipment
to the network.
2.2.7 Data Types Communicated to the Master
The DeviceNet Network allows different types of connection for the data exchange between the network master
and the other equipments. For the SSW-06 soft-starter, the connection types available for I/O data transmission
depend on the used communication kit:
■ DeviceNet Fieldbus Kit: Only messages of the Polled type can be transmitted.
■ DeviceNet Drive Profile Fieldbus Kit: Messages of the Polled type, as well as Change of State & Cyclic
can be transmitted.
Those connection types are programmed by means of the DeviceNet network master configuration tool, in
order that the soft-starter be able to communicate properly with the master. The amount of data that must be
programmed depends on the value programmed at the parameter P309, as indicated in the section 3.2.
