TIME (Time Keyword)
[General]
DESCRIPTION:
The TIME operand contains the value of the internal free running, real time clock. The returned value
represents the number of servo loop updates and is based on the TM command. The default value for the
TM command is 1000. With this update rate, the operand TIME will increase by 1 count every update of
approximately 1000usec. Note that a value of 1000 for the update rate (TM command) will actually set an
update rate of 1/1024 seconds. Thus the value returned by the TIME operand will be off by 2.4% of the
actual time.
The clock is reset to 0 with a standard reset or a master reset.
The keyword, TIME, does not require an underscore (_) as with the other operands.
