7.1 Diagnostic messages
7.1.1 Classification and error responses
The diagnostic messages of the motor controller are classified as errors, warnings or information.
Type Description FHPP
Error
(Error)
When an error occurs, the motor controller changes to the
error status (DOUT READY 1
è
0). Errors always generate an
error reaction that has an effect on the behaviour of the
drive, e.g. stop behaviour, switching off the output stage
(
è
Tab. 7.2). To restore the ready status, errors require:
– elimination of the error cause
– an acknowledgment or a restart (reset)
SCON.FAULT bit is set
Warning
(Warning)
Warnings have no influence on the behaviour of the drive
and do not need to be acknowledged. To avoid a sub­
sequent error: Clarify the cause of the warning and elimin­
ate it.
The SCON.WARN bit
is set. If the cause
has been eliminated,
the bit is automatic­
ally deleted again.
Information
(Information)
Information messages have no influence on the behaviour
of the drive and do not need to be acknowledged.
