9.3.5. Supported PDO Transmission Types
Various transmission modes can be selected for each PDO.
For RX PDO, the following modes are supported:
Table 3: RX PDO Transmission Mode
Transmission Type
Mode
Description
0 – 240
Synchronous
The received data will be transferred to the drive active control register when the
next sync message is received.
254, 255
Asynchronous
The received data will be transferred to the drive active control register
immediately without delay.
For TX PDO, the following modes are supported:
Table 4: TX PDO Transmission Mode
Transmission Type
Mode
Description
0
Acyclic synchronous
TX PDO will only be sent out if the PDO data has changed and PDO will be
transmitted on reception of SYNC object.
1 - 240
Cyclic synchronous
TX PDO will be transmitted synchronously and cyclically. The transmission type
indicates the number of SYNC object that are necessary to trigger TX PDO.
254
Asynchronous
TX PDO will only be transferred once corresponding RX PDO has been received.
255
Asynchronous
TX PDO will be transferred at anytime following a PDO data value change.
