Wrong handwheel reading (counting).

Error when initializing the chip. The CNC does not detect the Sercos board or overflow at the DPRAM of the SERCON due to too many axes and data to be transmitted in the cyclic channel.

Timeout when requesting Sercos ring initialization.

Failed Sercos ring initializing process due to fiber optics connection problems, wrong CNC and drive parameter settings, problems on Sercos or drive boards, etc.

Timeout when resetting errors after initializing the Sercos ring.

Error when resetting errors after initializing the Sercos ring.

Depending on the type of handwheel (CAN keyboard, CAN counter, local, RCS-S module, etc.), check for coherence and communication level of the corresponding bus as well as the feedback input connection.
