CANopen communication parameter settings
Select the menu Parameters W Fieldbus W CANopen to adapt the CANopen
communication parameters of the 931E/K servo positioning controller to your CAN−bus
network.
931e_330
You can select the following communication parameters:
ƒ Baud rate:
This parameter determines the baud rate for the CANopen bus.
ƒ Basic node number:
This parameter determines the "basic node number" of the device which is used to
calculate the "effective" node number. In addition, the digital inputs can be considered
in the calculation of the effective node number (see below).
The identifiers of the individual messages are based on the node number. In a CANopen
network, all node numbers may only be assigned once.
ƒ Adding DIN0 ... DIN3 to the node number:
The value of the digital inputs DIN0 ... DIN3 is added to the basic node number. The
input combination is only read when the CANopen interface is activated or after a reset
of the 931E/K servo positioning controller.
In this way, it is possible to assign up to 16 different device numbers at the digital inputs
through simple bridges after 24V.
If you want to use this function, the digital inputs must be parameterised accordingly.
Click the "..." button to open the menu for the digital input settings.
The Effective node number field displays the node number resulting from basic node
number and offset.
Use the CANopen active checkbox to activate and deactivate the fieldbus communication
with the set parameters. The setting will be accepted immediately, i.e. there is no reset
required to activate or deactivate the CANopen interface.
