RxPDO
When any change in the mapped data happens,
RxPDO data is sent out immediately. The data
the slave receives is valid only when receiving
the next SYNCH message. RxPDO data is not
sent out if there is no change in the data.
SYNCH
non-cycle
TxPDO
When any change in the mapped data happens
and the slave receives the SYNC message, the
data are sent out immediately. The TxPDO data
are valid immediately after master receives them.
TxPDO data is not sent out if there is no change
N
（N:1–240）
RxPDO
After N messages are sent out, and regardless of
whether the mapped data changes, the data that
the slave receives is valid only when receiving
SYNCH
cycle
TxPDO
After N messages are sent out and regardless of
whether the mapped data is changed, the data
that the master receives is valid at once.
254
RxPDO
The mapped data is sent out immediately when it
changes and is valid when the slaves receives it.
RxPDO data is not sent out if there is no change
ASYNCH
TxPDO
The slave sends out the data once every one
Event timer time. After that, the TxPDO data is
not allowed to be sent out within an inhibit timer
time.
When the Event timer and Inhibit timer are both
equal to 0, the slave sends TxPDO data to the
master immediately when the data changes, and
the data that master receives is immediately
Note:
Synchronous transmission type can fulfill multi-axis motion at the same time.
If you monitor a real-time changing parameter such as the actual rotation speed of the motor, set
the TxPDO to the synchronous transmission type; otherwise the frequent change in the slave data
can block the CANopen network.
After you finish setting the above parameters, double click the master device to display the Node List Setting
dialog box. Select ASDA-A2 Drive, and click > to move the A2 drive to the right-side list, and then download
the configured data.
