MM4005 XS — Read trace sample rate
Usage IMM PGM MIP
Syntax XS
Parameters
None.
Description This command reads the trace acquisition period. This is the period that
will be used to sample the real and desired positions of a motion device
and store the values in memory.
NOTE
The returned value usually differs from the one preset in the SP com-
mand because it reflects the real clock used for the timer. For that rea-
son, the sample period is reported with at least 10 decimal points.
Returns XSnn
xx
— Real trace sample period, in seconds.
.
Errors S — Communication time-out.
Rel. Commands SP — Set trace sample rate.
TM — Set trace mode.
Example
SP0.005 | Set global trace sample period to 5 ms.
GQ1000 | Enable global trace mode and acquire 1000 samples.
2PR0.2 |
Start a relative motion on axis #2 and the acquisition process.
XS | Read the global trace sample period.
XS0.005003436196
| Controller returns the real sample rate, in seconds.
XT — Tell number of elements in the trajectory
Usage IMM PGM MIP
Syntax XT
Parameters
None.
Description This command retrieves from the controller the number of valid elements
that have been loaded into the trajectory.
Returns XTnn
nn
— Number of elements.
Errors S — Communication time-out.
Rel. Commands AT — Tell the element number under execution.
LT — Extended list of the trajectory.
Example NT | Reset trajectory buffer.
XT | Read number of elements.
XT0 | Controller returns 0.
