Emergency messages
Emergency messages are generated in the EtherCAT slave when device-internal
errors or malfunctions occur and are sent via the mailbox mechanism to the
EtherCAT master. No Emergency messages can be generated in STÖBER
devices by:
•
Incorrect sync manager parameterization during EtherCAT system start
•
Entering or leaving the malfunction device state (as with CANopen
®
)
•
Error during change of state of the EtherCAT state machine
8.1
Error Device State
To implement the mechanism described in CANopen
®
, the inverter continuously
monitors the device state. If this state changes to the fault or malfunction reaction
active state, the emergency message is sent exactly once with one of the error
codes described below. When the fault state is exited with an acknowledgment,
an emergency message is sent with the "no error" error code. This procedure
automatically keeps the master informed of the occurrence of a fault and when
this fault state was exited, and what the precise cause of the fault was.
The inverter specifies three pieces of information on the type of malfunction in the
message as required by CANopen
®
:
The inverter changes to fault 41:Temperature motor TMS:
The inverter exits the fault:
Coding of the error code in the first and second bytes and the error register in the
third byte corresponds to specifications from the CiA
®
/DS-301 and CiA® DSP402
profiles. The fourth byte contains the value of the STÖBER parameter
E82 event
type
. The fifth byte contains the contents of
E43 event cause
.
