Illustration 6.49 Behavior When an Error Occurs During Abort
of Functionality
A value of 0 is not allowed for the inputs pTraceBuffer,
TraceBufferSize, SampleCount, and SubSampling. For the
input SignalIDs, at least the 1
be >0, otherwise the function block signals an error.
For the input SampleCount, the value, multiplied by the
number of valid SignalIDs, must not exceed the TraceBuf-
ferSize and must not exceed the maximum available trace
buffer size of the servo drive (see chapter 2.7.2 Trace).

Data Default Description
type value
BOOL FALSE Starts the trace
functionality at rising edge
and keeps on polling until
the data is available.
BOOL FALSE Abort the ongoing trace.
New values are only
evaluated on a rising edge
of Execute.
UDINT 0 Reference to a buffer
where the read trace data
will be placed; Use ADR()
function
UDINT 0 Size of the trace buffer;
use SIZEOF() function.
Size of the provided buffer
given in Byte.
ddFastTas Sampling rate of the trace.

ARRAY[0.. [0, 0, 0, 0, IDs of the signals to be

UDINT of constants: AxisTrace-
Signals.
UDINT 0 ID of the signal used for
triggering. Available in the
list of constants: AxisTrace-
Signals.
Set the value to 0 for
instant tracing.
USINT 10 Amount of pre-trigger
history [in percentage].
Value range: 0–100
REAL 0.0 Level at which the device
triggers (in trigger signal
units).
BOOL TRUE TRUE: Triggers on rising
slope.
FALSE: Triggers on falling
slope.
BOOL The trace has successfully
been recorded and read
from the device.
BOOL The function block is not
finished and new output
values are to be expected.
