Emergency requests / Emergency messages
Emergency messages are sent to the EtherCAT master once when the error status of the controller
changes, i.e. ...
• when an error in the inverter or in the communication module occurs or
• 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 Servo Drive 9400 is displayed in code
.
