Axes assignment
The GX-EC0211 and GX-EC0241 encoder input slaves will introduce 2 axes
(ATYPE=69) to the Trajexia system. The axis numbers assigned depend on
the node address setting and the AXIS_OFFSET parameter, using the
following rule:
Axis No. 1 = (Node Address -1) + AXIS_OFFSET
Axis No. 2 = (Node Address - 1) + AXIS_OFFSET + 1
This offset (AXIS_OFFSET) needs to be specified per TJ2-ECT__. Please
note that the node addresses per TJ2-ECT__ need to be unique and the
resulting axis numbers must be unique in the system.
Example:
TJ2-MC__ + TJ2-ECT16 + GX-EC0241
• Node address: 02
• AXIS_OFFSET SLOT(0) = 0
• Assigned node addresses: 2 and 3
• Assigned axis numbers: 1 and 2
Note
An Encoder Input Slave Unit will get 2 axes assigned. These will
always be sequential and should not conflict with other axes in the
system.
