<GMA> array in masks


The predefined <GMA> array is used to conveniently program the <MULTIGOTO> command postprocessor either as a technology command program or as a mask. The <GMA> array like the <CLD> array is initialized before the command is processed. Every item of the <GMA> array corresponds to an axis in the machine scheme.

The <GMA> array usage syntax in masks is different from the postprocessor program's code: when used in a mask the "GMA" keyword and brackets are omitted. To access a <GMA> array item's property when programming a mask for the <MULTIGOTO> command use the quoted name of the axis and the property name without quotes separated by a point. For example to put the current value of the coordinate named <AxisXPos> into a NC-program the mask <X[“AxisXPos”.Vn]> should be used.

The following are examples of accessing <GMA> arrays items:

  • <"<AxisName>".OutFlag> – whether the coordinate is present in current <MULTIGOTO> command.
  • <"<AxisName>".Vn> – current value of the coordinate.
  • <"<AxisName>".Vp> – previous value of the coordinate.
  • <"<AxisName>".Axis> – coordinate name in the machine scheme.
  • <"<AxisName>".Reg> – name of the register bound to the coordinate.
  • <"<AxisName>".TurnCount> – number of full revolutions (360 degrees) of the current movement of rotatable axis.
  • <"<AxisName>".Dir> – direction of rotation.

<AxisName> – name of the machine coordinate.

The following example writes the <X>, <Y> and <Z> coordinates values into the NC-program passed through the <MULTIGOTO> command for the axes <AxisXPos>, <AxisYPos> and <AxisZPos> respectively.

 

X[“AxisXPos”.Vn] Y[“AxisYPos”.Vn] Z[“AxisZPos”.Vn]
