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 $AN_ESR_TRIGGER=1– and/or dependent on alarms that trigger follow-up mode (bit13=2000H):IDS=02 WHENEVER ($AC_ALARM_STAT B_AND 'H2000')>0 DO$AN_ESR_TRIGGER=1– and also dependent on EG synchronized operation (if, for example, Y is defined as EGfollowing axis and if the maximum allowed deviation of synchronized operation shallbe 100 mm):IDS=03 WHENEVER ABS($VA_EG_SYNCDIFF[Y])>0.1 DO $AN_ESR_TRIGGER=1– or (summarized) dependent on all three trigger preconditions + PLC + input:IDS=01 WHENEVER ($AA_ESR_STAT[A] > 0) AND(($AC_ALARM_STAT B_AND 'H2000')> 0) AND(ABS($VA_EG_SYNCDIFF[Y]) > 0.1) OR($A_DBB[0] > 0) OR($A_PBB[0] > 0) DO $AN_ESR_TRIGGER=14.5.2 NC-controlled reactionsExample using NC-controlled reactions. The important details are specified.ExerciseThe A axis is to operate as the generator drive, while the X axis should retract 10 mm atmaximum speed in the event of a fault, and axes Y and Z should stop after a delay of 100ms so that the retraction axis has time to cancel the mechanical coupling.PreconditionsThe "Extended stop and retract", "Static synchronous actions" and "ASUB" options must beavailable.
