Node Address settings
fig. 122
Set the address selector of the 3G3AX-MX2-ECT to the required node
address by using the X1 (right) and X10 (left) rotary switches.
The setting range for the node address setting rotary switch is 00 to 99.
When the rotary switches are set to 00, the node address will be assigned
automatically, depending on the position in the network, starting from 1
sequentially.
The axis assigned depends on the node address setting and the
AXIS_OFFSET
parameter, using the following rule:
Axis No. = (Node Address -1) +
AXIS_OFFSET
This offset (
AXIS_OFFSET
) needs to be specified per TJ2-ECT__. Please
note that the node address per TJ2-ECT__ needs to be unique.
Example:
TJ2-MC__ + TJ2-ECT16 + 3 MX2 Inverters
•
Node address setting: 01, 04 and 07
•
AXIS_OFFSET SLOT(0) = 4
Assigned axis numbers: 4, 7 and 10.

Note
The set node address is read only once when the inverter power
supply is turned ON. If the setting is changed after the power sup-
ply is turned ON, the new setting will not be used until the next
time that the power is turned ON.
Do not change the setting on the rotary switches after the power
supply has been turned ON.
Note
When using an MX2 Inverter through the EtherCAT interface it will
get assigned an axis number and is controlled through axis com-
mands and parameters. The Inverter commands like
INVERTER_READ
and
INVERTER_WRITE
are not applicable.
This is different compared to interfacing an Inverter through the
MECHATROLINK-II network.
