11.3 Emergency requests / Emergency messages
Emergency messages are sent to the EtherCAT master once when the error status of the inverter
changes, i.e. ...
• when an error in the inverter or in the communication module occurs;
• when an internal error of the communication module is eliminated.
An "Emergency Request" on the fieldbus consists of the components "Mailbox Header", "CANopen
Header" and the actual "Emergency Message":
The emergency message last sent by the Inverter Drive 8400 is displayed in code C13867 .
Code C13887 serves to select the error responses where no emergency messages are to be sent to
the EtherCAT master.
