7 Parameter setting
The EtherCAT interface is parameterised under the menu Parameters
W Fieldbus W
EtherCAT
W Operating parameters:
931K_100
For activating the EtherCAT interface the following parameter has to be set:
ƒ Basic node number
In order to unambiguously identify the nodes in the network, a node number which may
only appear once in the network must be assigned to each node. Via this node number the
device is addressed.
As an additional option there is the possibility of basing the node number of the 931K servo
position controller on the external configuration. After the reset the input combination of
the digital inputs DIN0...DIN3 is added once to the basic node number.
Finally the EtherCAT protocol in the 931K servo position controller can be activated. Please
note that you can only alter the parameters mentioned when the protocol is deactivated.
)
Note!
Please note that the parameterisation of the EtherCAT functionality is only
preserved after a reset if the parameter set has been saved in the 931K servo
position controller.
EtherCAT communication can also be monitored in the Small Drives Control via the PDO
editor Parameters
W Fieldbus W EtherCAT W PDO editor.
In a first step only communication should be monitored via this field. During the
initialisation the control defines the PDO data transfer area and, depending on the XML
device description and start−up settings of the control, assigns a data area (different
objects).
The following graphic representation shows the PDO area which is displayed when the ex
works settings are maintained.
In the NMT status field it can be viewed that the device is in the "Pre−operational" state. It
is not connected to a control and is not "activated".
