Use the
command to define the rate at which the virtual master internal count frequency may

Use the
command to define the virtual master count frequency. The "virtual master" is an internal
FVMFRQ
count source, intended to mimic the counts which might be received on an external encoder port. Just as
may be encountered with an external encoder, this count source may speed up, slow down, stop, or count
backwards.
The count source has a variable count frequency, defined by the user. The count source is always enabled,
counting at the signed rate specified by this command. To start and stop the count source, specify non-zero
or zero values, respectively, for the
The rate at which the count frequency may change is specified in counts per second per second with the
command, allowing smooth changes in master velocity and direction.
