2-dimensional setpoint value ($AC_MEAS_TYPE = 20)
Setpoints for two dimensions can be defined using this measuring method. Any combination
of 2 out of 3 axes is permissible. If three setpoints are specified, only the values for the abscissa
and the ordinate are accepted. The tool is not taken into account.
This is a purely actual value memory preset.
