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.
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 (Wait) command to SP (Speed) commands.
While Moving Yes Minimum n Value 250
In a Program Yes Maximum n Value 20,000
Command Line Yes Default Value 1000
Can be Interrogated Yes Default Format 5.0
Used as an Operand Yes
TM 250 Set sample rate to 250 µsec (This will multiply all
speeds by four and all acceleration by eight)
TM 1000 Return to default sample rate
