Preset actual value memory for special axes only
Comment
; Offset between WCS and ENS
; WCS(x) = 0; ENS(x) = 10
; Set all input variables to invalid
; Measuring type for preset actual value mem-
ory
; Measuring plane is G17
; ENS_REL for 1st measuring point
; Pick up all axis positions
; Setpoint position is relative to ENS
; Setpoint position in the relative ENS co-
ordinate system
; $P_RELFR
; Calculation of $P_RELFR; PI SETUDT(6)
; Activation; PI SETUDT(7)
Meaning
Validity bits for input variables
Actual values of the axes
Setpoint position of the individual axes *
0: Coarse offset, 1: Fine offset *
