SQ S e t global sample rate
Usage I I I IMM • PGM • MIP
Syntax S Q n n or SQ?
Parameters
Description n n [float] T r a c e sample period.
Range n n 0 . 0 0 0 3 to 9.
Reading of the global sample rate value.
Units n n S e c o n d s .
Defaults n n M i s s i n g : 0.0003.
Out of range: Nearest range limit.
Non-increment: Rounded to nearest increment.
Description T h i s command sets the sample period for the global trace function. The
global trace mode is similar to the trace mode but it samples all four axes
in the same time. Refer to the global trace command GQ for the description
on how to use the global trace mode.
NOTE
The sampling is done in increments of the servo loop cycle. Since the
servo cycle is not exactly 0.0003 sec, use the SQ? command to read the
actual global trace sample interval used.
The value returned with SQ? may differ slightly from the one preset with
the SQnn command because it reflects the real clock used for the timer.
For that reason, the sample period is reported with at least 10 decimal
points.
Returns I f the sign "?" takes place of nn, this command returns the global sample
rate value.
Errors C — P a r a m e t e r out of limits.
Rel. Commands G Q — S e t global trace mode.
Example
SQ0.002 S e t global trace period to 2 ms.
SQ? R e a d actual global trace period.
SQ0.0020013744 78 C o n t r o l l e r returns actual global trace period.
2GQ500 S e t global trace mode for axis #2 and 500 data points.
2PRO.1, 3PRO.1, WS P e r f o r m a motion of 0.1 units on axis #2 and #3 and wait for stop.
