3.6.11 RFS (Reference Search)
The TMCM-3212 has a built-in reference search algorithm. The reference search algorithm provides
different refrence search modes. This command starts or stops the built-in reference search algorithm.
The status of the reference search can also be queried to see if it already has finished. (In a TMCL program
it mostly is better to use the WAIT RFS command to wait for the end of a reference search.) Please see the
appropriate parameters in the axis parameter table to configure the reference search algorithm to meet
your needs (please see chapter 4).
Internal function:
The internal reference search state machine is started or stoped, or its state is queried.
Related commands: SAP, GAP, WAIT.
Mnemonic: RFS <START|STOP|STATUS>, <motor>
