Synchronized actions
Formulate trigger condition as static synchronous action(s), e.g.:
; dependent on intervention of generator axis:
IDS=01 WHENEVER $AA_ESR_STAT[A]>0 DO $AC_ESR_TRIGGER=1
; and/or dependent on alarms that trigger tracking mode
; activate (Bit13=2000H):
IDS=02 WHENEVER ($AC_ALARM_STAT B_AND 'H2000')>0 DO $AC_ESR_TRIGGER=1
; and also dependent on EG synchronized operation (if, for example, Y is defined as EG
following axis and if the maximum allowed deviation of synchronized operation shall be 100
mm):
IDS=03 WHENEVER $VA_EG_SYNCDIFF[Y]>0.1 DO $AC_ESR_TRIGGER=1
4.5.3 Fast retraction of an axis on stop thread cutting
Suppressing path interpolation for an axis
During thread cutting, the path interpolation of X is suppressed for a stop and a movement at
maximum speed to position POLF[X] is interpolated instead. The motion of the other axes
continues to be determined by the programmed contour or the thread lead and spindle
speed.
