MF (Motion Forward)
[Trippoint]
DESCRIPTION:
The MF command is a trippoint used to control the timing of events. This command will hold up the
execution of the following command until the specified motor moves forward and crosses the position
specified. The units of the command are in quadrature counts. The MF command can also be used when
the encoder is the master and not under servo control, because the actual position is monitored.
ARGUMENTS: MFx, y, z, w or MFX=x or MFa, b, c, d, e, f, g, h where
x, y z, w, or a, b, c, d, e, f, g, h are signed integers
USAGE:
RELATED COMMANDS:
EXAMPLES:
NOTE: The accuracy of the MF command is the number of counts that occur in 2 msec. Multiply the speed by 2 msec to
obtain the maximum error. MF tests for absolute position. The MF command can also be used when the specified motor is
driven independently by an external device.
