Module response to 9400 standard device loss

Corrected from:
EtherCAT E94AYCET Firmware Version 3.00 communication module

Behaviour of the new version?
All Lenze EtherCAT modules (9400, 8400 and EMF 2192) externally supplied with 24V change to the ErrSafeOP EtherCAT state in the event of a standard device loss.



What happens?
The module remains in the OP EtherCAT state in spite of the 9400 standard device loss.

When does the problem occur?
If the communication between the Lenze standard device and the EtherCAT module is interrupted (e.g. mains switching of the 400V standard device supply).

Which products are affected?
EtherCAT E94AYCET FV 2.0 communication module
EtherCAT E94AYCET FV 1.01 communication module

Diagnostics options?
The module indicates the OP state even though no standard device exists at the moment.

Short-term measures/recommendations?
None
