MC-Basic:axis.NODEID
| Language: | English |
|---|
* EtherCAT:
This property is meant for use with Multi Axis drives, that is, a motion drive that appears as a single EtherCAT slave but can drive more than one motor.
In this case multiple axes can share the same Drive Address but are distinguished by Node ID.
For example, if MC is connected to 4 motion drives and the second drive is connected to 3 motors, the axes properties can be assigned as follows:
A1.Dadd = 1, A1.NodeID = 1
A2.Dadd = 2, A2.NodeID = 1
A3.Dadd = 2, A3.NodeID = 2
A4.Dadd = 2, A4.NodeID = 3
A5.Dadd = 3, A5.NodeID = 1
A6.Dadd = 4, A6.NodeID = 1
see EC_SETUP for details
 | IMPORTANT |
| Property can be set only after Ax.Dadd is already set (different from zero) |
| IMPORTANT |
| NodeID MUST be set to a value different from zero in order to enable the axis |
| IMPORTANT |
| In case of a regular single axis drive, the user must assign NodeID to 1. It is NOT done by default due to safety considerations |
