MC
FUNCTION: Motion Complete - "In Position"
DESCRIPTION:
The MC command is a trippoint used to control the timing of events. This command will
hold up execution of the following commands until the current move on the specified axis
or axes is completed and the encoder reaches or passes the specified position. Any
combination of axes may be specified with the MC command. For example, MC AB
waits for motion on both the A and B axis to be complete. MC with no parameter
specifies that motion on all axes is complete. The command TW sets the timeout to
declare an error if the encoder is not in position within the specified time. If a timeout
occurs, the trippoint will clear and the stopcode will be set to 99. An application program
will jump to the special label #MCTIME.
When used in stepper mode, the controller will hold up execution of the proceeding
commands until the controller has generated the same number of steps as specified in the
commanded position. The actual number of steps that have been generated can be
monitored by using the interrogation command TD. Note: The MC command is
recommended when operating with stepper motors since the generation of step pulses can
be delayed due to the stepper motor smoothing function, KS. In this case, the MC
command would only be satisfied after all steps are generated.
ARGUMENTS: MC nnnnnnnn
where
n is A,B,C,D,E,F,G or H or any combination to specify the axis or axes
