PMAC Program Command Specification 339
Example
PRELUDE1 CALL10 ; Insert a CALL10 before subsequent moves
X10 Y20 ; Implicit CALL10 before this move
X20 Y30 ; Implicit CALL10 before this move
...
OPEN PROG 10 CLEAR ; Subprogram
Z-1 ; Move down
DWELL 500 ; Hold position
Z1 ; Move up
RETURN
...
G71 X7 Y15 P5 ; G71 calls PROG 1000 N71000
X8 Y16 P5 ; With PRELUDE, G71 is implied (modal)
X9 Y15 P8 ; With PRELUDE, G71 is implied (modal)
G70 ; Stop modal canned cycles
...
OPEN PROG 1000
...
N70000 ; G70 subroutine
PRELUDE0 ; Stop PRELUDE calls
RETURN
N71000 ; G71 subroutine
PRELUDE1 G71.1 ; Make G71 modal by using PRELUDE
RETURN
N71100 ; G71.1 routine is what executes G71 modally
READ(X,Y,P) ; Read values associated with X, Y, and P
{action based on parameters}

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.
Remarks
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.
