TM (Time Base)
[Configuration]
DESCRIPTION:
The TM command sets the sampling period of the control loop. Changing the sampling period will
uncalibrate the speed and acceleration parameters. A negative number turns off the internal clock allowing
for an external source to be used as the time base. The units of this command are
µsec. If a multi-axis
system is configured the TM value is set in all controllers if set in the master.
ARGUMENTS: TM n
where
n is an integer in microseconds with a resolution of 125 microseconds.
USAGE:
OPERAND USAGE:
_TM contains the value of the sample time.
EXAMPLES:
NOTE: Although this manual refers to times in msec, think in terms of servo cycles. This includes
everything from a WT command to SP commands.

speeds by four and all acceleration by eight)
