Handling, Diagnostic and Service Functions
Parameter P-0-0031, Oscilloscope: time resolution determines the time
intervals in which measured values are recorded (sampling rate). It is
possible to select the time resolution on the time base of the position loop
clock (T
= N*T
).

The position loop cycle time depends on the control performance
(Advanced: T
= 250µs; Basic: T
pos
The control performance in turn depends on the hardware design of the
controller and the setting in P-0-0556, Control word of axis controller
(bit 2).
Status of the Oscilloscope Function
The parameter P-0-0029, Oscilloscope: status word displays the
current status of the oscilloscope function.
Parameter P-0-0029 contains, for example, status information on:
• start/end of recording
• trigger function
• status of trigger signal
• delay function
See also Parameter Description "P-0-0029, Oscilloscope: status
word"
Via parameter P-0-0037, Oscilloscope: internal trigger signal the
master is informed of the status of the internal trigger. As real-time control
information, this parameter can be parameterized both in the real-time
channel of the interface and as hardware output.
Displaying the Number of Valid Measured Values
After a measurement the parameter P-0-0150, Oscilloscope: number of
valid measured values displays the number of detected measured
values in the ring buffer. When the ring buffer has been completely filled
with the length determined in parameter P-0-0032, Oscilloscope: size of
memory, the size of memory is displayed in this parameter.
