ABS

Function

Select absolute position mode for axes in addressed coordinate system.

Scope

Coordinate-system specific

Syntax

ABS

ABS ({axis}[,{axis}...])

where:

• {axis} is a letter (X, Y, Z, A, B, C, U, V, W) representing the axis to be specified, or

the character R to specify radial vector mode

Note:

No spaces are permitted in this command.

Remarks

This command, without any arguments, causes all subsequent positions for all axes in the

coordinate system in motion commands to be treated as absolute positions (this is the default

condition). An ABS command with arguments causes the specified axes to be in absolute

mode, and all others to remain unchanged.

If R is specified as one of the ‘axes’, the I, J, and K terms of the circular move radius vector

specification will be specified in absolute form (i.e. as a vector from the origin, not from the

move start point). An ABS command without any arguments does not affect this vector

specification. The default radial vector specification is incremental.

If a motion program buffer is open when this command is sent to PMAC, the command will

be entered into the buffer for later execution.

Example

ABS(X,Y) ........ ; X & Y made absolute – other axes and radial vector left unchanged

ABS .................... ; All axes made absolute – radial vector left unchanged

ABS(R) ; Radial vector made absolute – all axes left unchanged
