15 Emergency messages
Emergency messages are messages that are actively sent from the device to the EtherCAT
®
master if certain events/prob-
lems occur. They are an unverified service which is based on CoE. In this way, all errors can be indicated to the master by
the slave. This takes the form of messages which are specified in ETG.1000.6.
An emergency message is structured as follows:
The following emergency messages are supported by the device:
CoE emergency message
2 bytes 1 byte 5 bytes
Error code Error register Diagnostic data
Error code (hex) Error register Diagnostic data (hex) Localization Meaning
3001 Bit 2 set 00, 01, 00, 00 Device level Supply voltage overcurrent
3002 Bit 2 set 00, 02, 00, 00 Device level Supply surge voltage
3003 Bit 2 set 00, 03, 00, 00 Device level Supply undervoltage
3004 Bit 2 set 00, 04, 00, 00 Device level Surge voltage of actuator supply
3005 Bit 2 set 00, 05, 00, 00 Device level Undervoltage of actuator supply
4001 Bit 4 set 00, 06, 00, 00 Device level Overtemperature
The device sends emergency messages for an incoming and outgoing error. Once the problem has been
solved, an emergency message with the error code 0000
hex
(reset error) is sent by the slave.
The value of the corresponding bit in the error register is then 0. The diagnostic data value does not change.
