Since the
units are in terms of counts/unit, all distances will thus be internally represented in counts.
SCLD
For instance, if your distance scaling factor is 10000 (
the actual distance moved will be 750,000 counts. (10000 x 75 = 750,000 counts)
This command is useful for allowing the user to specify distances in any unit. For example, if the user had a
25000 step/revolution drive and wanted distance units in terms of revolutions, then
25000, and scaling should be enabled (
As the distance scaling factor (
positions to the right of the decimal point also change (see table below). A distance value with greater
resolution than allowed will be truncated (e.g., if scaling is set to
would be truncated to
D1.9999
SCLD (counts/unit)
1 - 9
10 - 99
100 - 999
1000 - 9999
10000 - 99999
100000 - 999999
If you are operating in the preset positioning mode (MCØ), when the distance scaling factor (SCLD) and
the distance value are multiplied, a fraction of one step may possibly be left over. This fraction is
truncated when the distance value is used in the move algorithm. This truncation error can accumulate
over a period of time, when performing incremental moves continuously in the same direction. To
eliminate this truncation problem, set the distance scale factor (SCLD) to 1, or a multiple of 10.
