F.2 Diagnostic messages
F.2.1 Error management
Error management makes it possible to parameterise the reaction to diagnostic messages of the EMCA.
These diagnostic messages can be classified as error, warning or information. The reactions to the dia­
gnostic messages can be established dependent on the classifications made.
Elimination of the malfunction is described in the corresponding diagnostic message
è
page 385.
F.2.2 Reactions to messages
Depending on the message, the following reactions can be configured:

Description PNU Page
Error
(Error)
When an error occurs (SCON.FAULT, B3 = 1), the EMCA
changes to the status “Malfunction recognised (T7)” of the
FHPP finite state machine
è
page 117. Errors always generate
a reaction to the malfunction (S6) that has an effect on the
behaviour of the drive, e.g. stop behaviour, switching off of the
output stage
è
Tab. F.9. Steps required to restore the ready
status:
– Remedy the cause of the error and then acknowledge the
error (CCON.RESET, B3)

Warning
(Warning)
Warnings (SCON.WARN, B2 = 1) have no influence on the be­
haviour of the EMCA and do not need to be acknowledged. To
avoid a subsequent error, the cause of the warning must be
eliminated (SCON.WARN, B2 = 0). Warnings are displayed via
the status LED “ERROR”
