SP — Set trace sample rate
Usage • IMM
■
PGM
■
MIP
Syntax S P n n or SP?
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 trace 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 trace function. Refer to the
trace command TM for the description on how to use the 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 SP? command to read the
actual trace sample interval used.
The value returned with SP? usually differs from the one preset in the
SPnn 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 trace sample
rate value.
Errors C — Parameter out of limits.
Rel. Commands T M — S e t trace mode.
Example
SP0.002 I S e t trace period to 2 ms.
SP? I R e a d actual trace period.
SP0.0020013744 78 I Controller returns actual trace period.
2TM500 I S e t trace mode for axis #2 and 500 data points.
2PRO.1, WS I P e r f o r m a motion of 0.1 units on axis #2 and wait for stop.
TT I R e a d trace data.
