4. Set Parameter 25 - [COS Status Mask] for the bits in the Logic Status

word that should be checked for changes. The bit definitions for the
Status Mask will depend on the drive to which the adapter is connected.
Refer to

Appendix D

or the drive documentation.

5. Set Parameter 26 - [COS Fdbk Change] for the amount of change to

the Feedback that is required to trigger a Change of State message.

Using Cyclic Data Exchange

With cyclic data exchange, a PDO is sent periodically.

1. With the CANopen configuration tool, set the transmission mode of the

TPDO1 (Transmit PDO) of the adapter to “0” (synchronous) or “254”
(asynchronous).

2. Set Parameter 24 - [PDO1 Trigger] to “1” (Cyclic).

3. Set Parameter 27 - [Cyclic Interval] for the desired time interval

between two transmissions.
