PSET

Function: Redefine current axis positions (Position SET)

Type: Motion program

Syntax: PSET{axis}{data} [{axis}{data}...]

where:

 {axis} is the character specifying which axis (X, Y, Z, A, B, C, U, V, W);

 {data} is a constant or an expression representing the new value for this axis position

This command allows the user to re-define the value of an axis position in the middle of the program. It

is equivalent to the RS-274 G-Code G92. No move is made on any axis as a result of this command – the

value of the present commanded position for the axis is merely set to the specified value.

Internally, this command changes the value of the position bias register for each motor attached to an axis

named in the command. This register holds the difference between the axis zero point and the motor zero

(home) point.

This command automatically forces a temporary pause in the motion of the axes; no moves are blended

through a PSET command. For more powerful and flexible offsets that can be done on the fly (X, Y, and

Z axes only), refer to the matrix manipulation commands such as ADIS and IDIS.

Examples:

X10Y20

PSET X0 Y0 ; Call this position (0,0)

N92000 READ(X,Y,Z) ; To implement G92 in PROG 1000

PSET X(Q124)Y(Q125)Z(Q126) ; Equivalent of G92 X..Y..Z..
