9.4 Servo drive messages
9.4.1 Status of messages
Messages can have the following statuses:
Status Description
Active The triggering diagnostic event is still active.
Cancelled The triggering diagnostic event is no longer active. The message was therefore
cancelled internally.
Acknowledged The triggering diagnostic event is no longer active. The message was therefore
cancelled internally. The message was then acknowledged by an external com-
mand or an external signal.
Tab. 422 Status of messages
The messages remain active as long as the diagnostic event is active (e. g. high temperature of power
unit). Once the diagnostic event is no longer active, the message is cancelled by the firmware and can
be acknowledged. The acknowledgement resets the error response of the device again (e. g. LED dis-
play). The device switches to the error status when errors occur. The error status remains active until
all of the errors have been cancelled by the firmware and have then been acknowledged by an external
command or an external signal. The error status is quit again once all of the error messages have been
acknowledged.
