Diagnostics and error handling

6.4

Faults and warnings

The CMAX permanently monitors the operating status and issues corresponding diagnostic messages

in the event of deviations from the nominal status.

Diagnostic messages for malfunctions are categorised as faults or warnings, depending on the cause

and effect, and can be evaluated in detail and processed.

Malfunctions

Effect

Acknowledge

Faults

Events and statuses that jeo­

pardize or prevent correct op­

eration of the CMAX.

 Section 6.4.1

Required

è

 Section 6.4.2

Warnings

Events and statuses that may

impair operation.

–

SCON.WARN = 1 is set

–

The sequence control and the axis are not

affected

Not required

Tab. 6.5

Faults and warnings

List of faults and warnings 

è

 Section 6.4.4.

Some diagnostic messages can be classified optionally as warning or fault with FCT or

PNU 228:03. Section 6.4.4 shows the step assigned at the plant (e.g. F2). Alternative

steps that can be set are listed in brackets. F2 (W) therefore means “factory setting step

F2, alternative step W”.

6.4.1

Effect on the sequence control and axis – error level

Dependent on the error level, faults and warnings have the following effect:

Status of status bits:  – = no effect;  0 = logic 0, 1 = logic 1; x = no updating

Tab. 6.6

Error levels

–

F1 (fault 1): The axis is stopped. Behaviour with stop 

è

 Communication profile description.

–

F2 (fault 2): Controller inactive, the drive moves using residual energy until it comes to rest. If com­

munication with the displacement encoder/sensor interface fails, the possibility exists that homing

may be lost (SPOS.REF = 0).

–

FS (system fault): It may no longer be possible to update the I/O data. 

Switching off/on required.
