Trace Settings (Drive) - Siemens SINUMERIK 828D Commissioning Manual

Trace settings (drive)

In the "Trace Settings (Drive)" window, you define the conditions for starting and stopping the
trace session:
Condition for Start trace
With "Start trace" softkey
If variable
Preprocessing time [s]:
Data storage on CU
Drive trace rate [μs]:
Condition for Stop trace

Commissioning Manual, 10/2015, 6FC5397-3DP40-5BA3
The recording is started immediately after pressing the "Start
trace" softkey.
The recording is activated after pressing the "Start trace"
softkey when the selected variable clearly satisfies the con‐
dition and the specified value.
The following conditions are offered:
● Positive edge
● Negative edge
● With bit mask
The "Bit mask" softkey is displayed when the "Bit mask" con‐
dition is selected in order to select the desired bits. Irrespec‐
tive of the maximum value (hexadecimal) which is possible
through the bit mask, a "Value" (decimal) can be entered at
which the trace recording starts precisely.
Example:
The trace recording is started when the following bits are set:
Bit 0 = 0; bit 1 = 1; bit 2 = 0; bit 3 = 1
Bit mask = fH Condition
Variable: CU/ With bit mask
r722/3.3.1
☑ Bit 0
☑ Bit 1
☑ Bit 2
☑ Bit 3
The input of a preprocessing time corresponds to the func‐
tional parameter p4722 "Trace trigger delay":
● A positive preprocessing time starts the recording before
the trigger event.
● A negative preprocessing time starts the recording after
the trigger event.
When entering a preprocessing time, the entire duration of
the recording must be taken into account:
● If the preprocessing time is greater than the entire
duration of the recording, the entry is rejected.
● If too large a preprocessing time is entered, the trigger
event may not be recorded.
Enter a factor with the "Sampling rates" softkey to set the
effective sampling rate. With a higher sampling rate, the re‐
cording duration is also longer.
